Requirements
</h2>
<p>
You will need access to a Redis server to use these libraries.
You can experiment with a local installation of Redis Stack
(see
<a href="/docs/latest/operate/oss_and_stack/install/install-stack/">
Install Redis Stack
</a>
) or with a free trial of
<a href="/docs/latest/operate/rc/">
Redis Cloud
</a>
.
To interact with a Redis server without writing code, use the
<a href="/docs/latest/develop/tools/cli/">
Redis CLI
</a>
and
<a href="/docs/latest/develop/tools/insight/">
Redis Insight
</a>
tools.

</strong>
: the consumer group's name
</li>
<li>
<strong>
last-delivered-id
</strong>
: the ID of the last entry delivered to the group's consumers
</li>
<li>
<strong>
entries-read
</strong>
: the logical "read counter" of the last entry delivered to the group's consumers
</li>
<li>
<strong>
lag
</strong>
: the number of entries in the stream that are still waiting to be delivered to the group's consumers, or a NULL when that number can't be determined.
</li>
<li>
<strong>
pel-count
</strong>
: the length of the group's pending entries list (PEL), which are messages that were delivered but are yet to be acknowledged
</li>
<li>
<strong>
pending
</strong>
: an array with pending entries information (see below)
</li>
<li>
<strong>
consumers

</li>
<li>
The name of the consumer that fetched the message and has still to acknowledge it. We call it the current
<em>
owner
</em>
of the message.
</li>
<li>
The UNIX timestamp of when the message was delivered to this consumer.
</li>
<li>
The number of times this message was delivered.
</li>
</ol>
<p>
The following information is provided for each consumer:
</p>
<ul>
<li>
<strong>
name
</strong>
: the consumer's name
</li>
<li>
<strong>
seen-time
</strong>
: the UNIX timestamp of the last attempted interaction (Examples:
<a href="/docs/latest/commands/xreadgroup/">
<code>
XREADGROUP
</code>
</a>
,
<a href="/docs/latest/commands/xclaim/">
<code>
XCLAIM
</code>
</a>
,
<a href="/docs/latest/commands/xautoclaim/">
<code>
XAUTOCLAIM
</code>
</a>
)
</li>
<li>
<strong>
active-time
</strong>
: the UNIX timestamp of the last successful interaction (Examples:
<a href="/docs/latest/commands/xreadgroup/">
<code>
XREADGROUP
</code>
</a>
that actually read some entries into the PEL,
<a href="/docs/latest/commands/xclaim/">
<code>
XCLAIM
</code>
</a>
/
<a href="/docs/latest/commands/xautoclaim/">
<code>
XAUTOCLAIM
</code>
</a>
that actually claimed some entries)
</li>
<li>
<strong>
pel-count
</strong>
: the number of entries in the PEL: pending messages for the consumer, which are messages that were delivered but are yet to be acknowledged
</li>
<li>
<strong>
pending
</strong>
: an array with pending entries information, has the same structure as described above, except the consumer name is omitted (redundant, since anyway we are in a specific consumer context)
</li>
</ul>
<p>
Note that before Redis 7.2.0,
<strong>
seen-time
</strong>
used to denote the last successful interaction.
In 7.2.0,
<strong>
active-time
</strong>
was added and
<strong>
seen-time
</strong>
was changed to denote the last attempted interaction.
</p>
<p>
The
<code>
COUNT
</code>
option can be used to limit the number of stream and PEL entries that are returned (The first
<code>
<count>
</code>
entries are returned).
The default
<code>
COUNT
</code>
is 10 and a
<code>
COUNT
</code>
of 0 means that all entries will be returned (execution time may be long if the stream has a lot of entries).

<h1>
Prometheus and Grafana with Redis Cloud
</h1>
<p class="text-lg -mt-5 mb-10">
Use Prometheus and Grafana to collect and visualize Redis Cloud metrics.
</p>
<p>
You can use Prometheus and Grafana to collect and visualize your Redis Cloud metrics.
</p>
<ul>
<li>
<a href="https://prometheus.io/">
Prometheus
</a>
is an open source systems monitoring and alerting toolkit that can scrape metrics from different sources.
</li>
<li>
<a href="https://grafana.com/">
Grafana
</a>
is an open source metrics visualization tool that can process Prometheus data.
</li>
</ul>
<p>
Redis Cloud exposes its metrics through a Prometheus endpoint. You can configure your Prometheus server to scrape metrics from your Redis Cloud subscription on port 8070.
</p>
<p>
The Redis Cloud Prometheus endpoint is exposed on Redis Cloud's internal network. To access this network, enable
<a href="/docs/latest/operate/rc/security/vpc-peering/">
VPC peering
</a>
or
<a href="/docs/latest/operate/rc/security/private-service-connect/">
Private Service Connect
</a>
. Both options are only available with Redis Cloud Pro. You cannot use Prometheus and Grafana with Redis Cloud Essentials.
</p>
<p>
For more information on how Prometheus communicates with Redis Enterprise clusters, see
<a href="/docs/latest/integrate/prometheus-with-redis-enterprise/">
Prometheus integration with Redis Enterprise Software
</a>
.
</p>
<h2 id="quick-start">
Quick start
</h2>
<p>
You can quickly set up Prometheus and Grafana for testing using the Prometheus and Grafana Docker images.
</p>
<h3 id="prerequisites">
Prerequisites
</h3>
<ol>
<li>
<p>
Create a
<a href="/docs/latest/operate/rc/databases/create-database/create-pro-database-new/">
Redis Cloud Pro database
</a>
.
</p>
</li>
<li>
<p>
Set up
<a href="/docs/latest/operate/rc/security/vpc-peering/">
VPC peering
</a>
.
</p>
</li>
<li>
<p>
Extract the Prometheus endpoint from the private endpoint to your database. The private endpoint is in the
<a href="https://cloud.redis.io/">
Redis Cloud console
</a>
under the
<a href="/docs/latest/operate/rc/databases/view-edit-database/#configuration-tab">
Configuration tab
</a>
of your database. The Prometheus endpoint is on port 8070 of the internal server.
</p>
<p>
For example, if your private endpoint is:
</p>
<div class="highlight">
<pre class="chroma"><code class="language-sh" data-lang="sh"><span class="line"><span class="cl">redis-12345.internal.<cluster_address>:12345
</span></span></code></pre>
</div>
<p>
The Prometheus endpoint is:
</p>
<div class="highlight">
<pre class="chroma"><code class="language-sh" data-lang="sh"><span class="line"><span class="cl">internal.<cluster_address>:8070
</span></span></code></pre>
</div>
</li>
<li>
<p>
Create an instance to run Prometheus and Grafana on the same cloud provider as your Redis Cloud subscription (for example, Amazon Web Services or Google Cloud). This instance must:
</p>
<ul>
<li>
Exist in the same region as your Redis Cloud subscription.
</li>
<li>
Connect to the VPC subnet that is peered with your Redis Cloud subscription.
</li>
<li>
Allow outbound connections to port 8070, so that Prometheus can scrape the Redis Cloud server for data.
</li>
<li>
Allow inbound connections to port 9090 for Prometheus and port 3000 for Grafana.
</li>
</ul>
</li>
</ol>
<h3 id="set-up-prometheus">
Set up Prometheus
</h3>
<p>
To get started with custom monitoring with Prometheus on Docker:
</p>
<ol>
<li>
<p>
Create a directory on the Prometheus instance called
<code>
prometheus
</code>
and create a
<code>
prometheus.yml
</code>
file in that directory.
</p>
</li>
<li>
<p>
Add the following contents to
<code>
prometheus.yml
</code>
. Replace
<code>
<prometheus_endpoint>
</code>
with the Prometheus endpoint.

<p class="text-lg -mt-5 mb-10">
Describes when data is encrypted at rest.
</p>
<p>
Redis Cloud databases write their data to disk whenever
<a href="/docs/latest/operate/rc/databases/configuration/data-persistence/">
persistence
</a>
is enabled.
</p>
<p>
Redis Cloud deployments are always encrypted at rest.

<p>
Persistent data is written to encrypted EBS volumes. For more information, see
<a href="https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/EBSEncryption.html">
Amazon EBS encryption
</a>
.

Disk encryption on Google Cloud
</h2>
<p>
All data written to disk on Google Cloud-based Redis Cloud deployments is encrypted by default. When deploying
a Redis Cloud database on Google Cloud, you don't need to take any actions to enable this encryption.

<p class="text-lg -mt-5 mb-10">
Introduction to Redis lists
</p>
<p>
Redis lists are linked lists of string values.
Redis lists are frequently used to:
</p>
<ul>
<li>
Implement stacks and queues.
</li>
<li>
Build queue management for background worker systems.
</li>
</ul>
<h2 id="basic-commands">
Basic commands
</h2>
<ul>
<li>
<a href="/docs/latest/commands/lpush/">
<code>
LPUSH
</code>
</a>
adds a new element to the head of a list;
<a href="/docs/latest/commands/rpush/">
<code>
RPUSH
</code>
</a>
adds to the tail.
</li>
<li>
<a href="/docs/latest/commands/lpop/">
<code>
LPOP
</code>
</a>
removes and returns an element from the head of a list;
<a href="/docs/latest/commands/rpop/">
<code>
RPOP
</code>
</a>
does the same but from the tails of a list.
</li>
<li>
<a href="/docs/latest/commands/llen/">
<code>
LLEN
</code>
</a>
returns the length of a list.
</li>
<li>
<a href="/docs/latest/commands/lmove/">
<code>
LMOVE
</code>
</a>
atomically moves elements from one list to another.
</li>
<li>
<a href="/docs/latest/commands/lrange/">
<code>
LRANGE
</code>
</a>
extracts a range of elements from a list.
</li>
<li>
<a href="/docs/latest/commands/ltrim/">
<code>
LTRIM
</code>
</a>
reduces a list to the specified range of elements.
</li>
</ul>
<h3 id="blocking-commands">
Blocking commands
</h3>
<p>
Lists support several blocking commands.
For example:
</p>
<ul>
<li>
<a href="/docs/latest/commands/blpop/">
<code>
BLPOP
</code>
</a>
removes and returns an element from the head of a list.
If the list is empty, the command blocks until an element becomes available or until the specified timeout is reached.
</li>
<li>
<a href="/docs/latest/commands/blmove/">
<code>
BLMOVE
</code>
</a>
atomically moves elements from a source list to a target list.
If the source list is empty, the command will block until a new element becomes available.
</li>
</ul>
<p>
See the
<a href="/docs/latest/commands/?group=list">

<h3 id="what-are-lists">
What are Lists?
</h3>
<p>
To explain the List data type it's better to start with a little bit of theory,
as the term
<em>
List
</em>
is often used in an improper way by information technology
folks. For instance "Python Lists" are not what the name may suggest (Linked
Lists), but rather Arrays (the same data type is called Array in
Ruby actually).
</p>
<p>
From a very general point of view a List is just a sequence of ordered
elements: 10,20,1,2,3 is a list. But the properties of a List implemented using
an Array are very different from the properties of a List implemented using a
<em>
Linked List
</em>
.
</p>
<p>
Redis lists are implemented via Linked Lists. This means that even if you have
millions of elements inside a list, the operation of adding a new element in
the head or in the tail of the list is performed
<em>
in constant time
</em>
. The speed of adding a
new element with the
<a href="/docs/latest/commands/lpush/">
<code>
LPUSH
</code>
</a>
command to the head of a list with ten
elements is the same as adding an element to the head of list with 10
million elements.
</p>
<p>
What's the downside? Accessing an element
<em>
by index
</em>
is very fast in lists
implemented with an Array (constant time indexed access) and not so fast in
lists implemented by linked lists (where the operation requires an amount of
work proportional to the index of the accessed element).
</p>
<p>
Redis Lists are implemented with linked lists because for a database system it
is crucial to be able to add elements to a very long list in a very fast way.
Another strong advantage, as you'll see in a moment, is that Redis Lists can be
taken at constant length in constant time.
</p>
<p>
When fast access to the middle of a large collection of elements is important,
there is a different data structure that can be used, called sorted sets.
Sorted sets are covered in the
<a href="/docs/latest/develop/data-types/sorted-sets/">
Sorted sets
</a>
tutorial page.

First steps with Redis Lists
</h3>
<p>
The
<a href="/docs/latest/commands/lpush/">
<code>
LPUSH
</code>
</a>
command adds a new element into a list, on the
left (at the head), while the
<a href="/docs/latest/commands/rpush/">
<code>
RPUSH
</code>
</a>
command adds a new
element into a list, on the right (at the tail). Finally the
<a href="/docs/latest/commands/lrange/">
<code>
LRANGE
</code>
</a>
command extracts ranges of elements from lists:

Note that
<a href="/docs/latest/commands/lrange/">
<code>
LRANGE
</code>
</a>
takes two indexes, the first and the last
element of the range to return. Both the indexes can be negative, telling Redis
to start counting from the end: so -1 is the last element, -2 is the
penultimate element of the list, and so forth.
</p>
<p>
As you can see
<a href="/docs/latest/commands/rpush/">
<code>
RPUSH
</code>
</a>
appended the elements on the right of the list, while
the final
<a href="/docs/latest/commands/lpush/">
<code>
LPUSH
</code>
</a>
appended the element on the left.
</p>
<p>
Both commands are
<em>
variadic commands
</em>
, meaning that you are free to push
multiple elements into a list in a single call:

An important operation defined on Redis lists is the ability to
<em>
pop elements
</em>
.
Popping elements is the operation of both retrieving the element from the list,
and eliminating it from the list, at the same time. You can pop elements
from left and right, similarly to how you can push elements in both sides
of the list. We'll add three elements and pop three elements, so at the end of this
sequence of commands the list is empty and there are no more elements to
pop:

Redis returned a NULL value to signal that there are no elements in the
list.
</p>
<h3 id="common-use-cases-for-lists">
Common use cases for lists
</h3>
<p>
Lists are useful for a number of tasks, two very representative use cases
are the following:
</p>
<ul>
<li>
Remember the latest updates posted by users into a social network.
</li>
<li>
Communication between processes, using a consumer-producer pattern where the producer pushes items into a list, and a consumer (usually a
<em>
worker
</em>
) consumes those items and executes actions. Redis has special list commands to make this use case both more reliable and efficient.
</li>
</ul>
<p>
For example both the popular Ruby libraries
<a href="https://github.com/resque/resque">
resque
</a>
and
<a href="https://github.com/mperham/sidekiq">
sidekiq
</a>
use Redis lists under the hood in order to
implement background jobs.
</p>
<p>
The popular Twitter social network
<a href="http://www.infoq.com/presentations/Real-Time-Delivery-Twitter">
takes the latest tweets
</a>
posted by users into Redis lists.
</p>
<p>
To describe a common use case step by step, imagine your home page shows the latest
photos published in a photo sharing social network and you want to speedup access.
</p>
<ul>
<li>
Every time a user posts a new photo, we add its ID into a list with
<a href="/docs/latest/commands/lpush/">
<code>
LPUSH
</code>
</a>
.
</li>
<li>
When users visit the home page, we use
<code>
LRANGE 0 9
</code>
in order to get the latest 10 posted items.
</li>
</ul>
<h3 id="capped-lists">
Capped lists
</h3>
<p>
In many use cases we just want to use lists to store the
<em>
latest items
</em>
,
whatever they are: social network updates, logs, or anything else.
</p>
<p>
Redis allows us to use lists as a capped collection, only remembering the latest
N items and discarding all the oldest items using the
<a href="/docs/latest/commands/ltrim/">
<code>
LTRIM
</code>
</a>
command.
</p>
<p>
The
<a href="/docs/latest/commands/ltrim/">
<code>
LTRIM
</code>
</a>
command is similar to
<a href="/docs/latest/commands/lrange/">
<code>
LRANGE
</code>
</a>
, but
<strong>
instead of displaying the
specified range of elements
</strong>
it sets this range as the new list value. All
the elements outside the given range are removed.
</p>
<p>
For example, if you're adding bikes on the end of a list of repairs, but only
want to worry about the 3 that have been on the list the longest:

The above combination adds new elements and keeps only the 3
newest elements into the list. With
<a href="/docs/latest/commands/lrange/">
<code>
LRANGE
</code>
</a>
you can access the top items
without any need to remember very old data.
</p>
<p>
Note: while
<a href="/docs/latest/commands/lrange/">
<code>
LRANGE
</code>
</a>
is technically an O(N) command, accessing small ranges
towards the head or the tail of the list is a constant time operation.
</p>
<h2 id="blocking-operations-on-lists">
Blocking operations on lists
</h2>
<p>
Lists have a special feature that make them suitable to implement queues,
and in general as a building block for inter process communication systems:
blocking operations.
</p>
<p>
Imagine you want to push items into a list with one process, and use
a different process in order to actually do some kind of work with those
items. This is the usual producer / consumer setup, and can be implemented
in the following simple way:
</p>
<ul>
<li>
To push items into the list, producers call
<a href="/docs/latest/commands/lpush/">
<code>
LPUSH
</code>
</a>
.
</li>
<li>
To extract / process items from the list, consumers call
<a href="/docs/latest/commands/rpop/">
<code>
RPOP
</code>
</a>
.
</li>
</ul>
<p>
However it is possible that sometimes the list is empty and there is nothing
to process, so
<a href="/docs/latest/commands/rpop/">
<code>
RPOP
</code>
</a>
just returns NULL. In this case a consumer is forced to wait
some time and retry again with
<a href="/docs/latest/commands/rpop/">
<code>
RPOP
</code>
</a>
. This is called
<em>
polling
</em>
, and is not
a good idea in this context because it has several drawbacks:
</p>
<ol>
<li>
Forces Redis and clients to process useless commands (all the requests when the list is empty will get no actual work done, they'll just return NULL).
</li>
<li>
Adds a delay to the processing of items, since after a worker receives a NULL, it waits some time. To make the delay smaller, we could wait less between calls to
<a href="/docs/latest/commands/rpop/">
<code>
RPOP
</code>
</a>
, with the effect of amplifying problem number 1, i.e. more useless calls to Redis.
</li>
</ol>
<p>
So Redis implements commands called
<a href="/docs/latest/commands/brpop/">
<code>
BRPOP
</code>
</a>
and
<a href="/docs/latest/commands/blpop/">
<code>
BLPOP
</code>
</a>
which are versions
of
<a href="/docs/latest/commands/rpop/">
<code>
RPOP
</code>
</a>
and
<a href="/docs/latest/commands/lpop/">
<code>
LPOP
</code>
</a>
able to block if the list is empty: they'll return to
the caller only when a new element is added to the list, or when a user-specified
timeout is reached.
</p>
<p>
This is an example of a
<a href="/docs/latest/commands/brpop/">
<code>
BRPOP
</code>
</a>
call we could use in the worker:

<p>
It means: "wait for elements in the list
<code>
bikes:repairs
</code>
, but return if after 1 second
no element is available".
</p>
<p>
Note that you can use 0 as timeout to wait for elements forever, and you can
also specify multiple lists and not just one, in order to wait on multiple
lists at the same time, and get notified when the first list receives an
element.
</p>
<p>
A few things to note about
<a href="/docs/latest/commands/brpop/">
<code>
BRPOP
</code>
</a>
:
</p>
<ol>
<li>
Clients are served in an ordered way: the first client that blocked waiting for a list, is served first when an element is pushed by some other client, and so forth.
</li>
<li>
The return value is different compared to
<a href="/docs/latest/commands/rpop/">
<code>
RPOP
</code>
</a>
: it is a two-element array since it also includes the name of the key, because
<a href="/docs/latest/commands/brpop/">
<code>
BRPOP
</code>
</a>
and
<a href="/docs/latest/commands/blpop/">
<code>
BLPOP
</code>
</a>
are able to block waiting for elements from multiple lists.
</li>
<li>
If the timeout is reached, NULL is returned.
</li>
</ol>
<p>
There are more things you should know about lists and blocking ops. We
suggest that you read more on the following:
</p>
<ul>
<li>
It is possible to build safer queues or rotating queues using
<a href="/docs/latest/commands/lmove/">
<code>
LMOVE
</code>
</a>
.
</li>
<li>
There is also a blocking variant of the command, called
<a href="/docs/latest/commands/blmove/">
<code>
BLMOVE
</code>
</a>
.
</li>
</ul>
<h2 id="automatic-creation-and-removal-of-keys">
Automatic creation and removal of keys
</h2>
<p>
So far in our examples we never had to create empty lists before pushing
elements, or removing empty lists when they no longer have elements inside.
It is Redis' responsibility to delete keys when lists are left empty, or to create
an empty list if the key does not exist and we are trying to add elements
to it, for example, with
<a href="/docs/latest/commands/lpush/">
<code>
LPUSH
</code>
</a>
.
</p>
<p>
This is not specific to lists, it applies to all the Redis data types
composed of multiple elements -- Streams, Sets, Sorted Sets and Hashes.
</p>
<p>
Basically we can summarize the behavior with three rules:
</p>
<ol>
<li>
When we add an element to an aggregate data type, if the target key does not exist, an empty aggregate data type is created before adding the element.
</li>
<li>
When we remove elements from an aggregate data type, if the value remains empty, the key is automatically destroyed. The Stream data type is the only exception to this rule.
</li>
<li>
Calling a read-only command such as
<a href="/docs/latest/commands/llen/">
<code>
LLEN
</code>
</a>
(which returns the length of the list), or a write command removing elements, with an empty key, always produces the same result as if the key is holding an empty aggregate type of the type the command expects to find.
</li>
</ol>
<p>
Examples of rule 1:

Tokenization
</h1>
<p class="text-lg -mt-5 mb-10">
Controlling text tokenization and escaping
</p>
<p>
Full-text search works by comparing words, URLs, numbers, and other elements of the query
against the text in the searchable fields of each document. However,
it would be very inefficient to compare the entire text of the query against the
entire text of each field over and over again, so the search system doesn't do this.
Instead, it splits the document text into short, significant sections
called
<em>
tokens
</em>
during the indexing process and stores the tokens as part of the document's
index data.
</p>
<p>
During a search, the query system also tokenizes the
query text and then simply compares the tokens from the query against the tokens stored
for each document. Finding a match like this is much more efficient than pattern-matching on
the whole text and also lets you use
<a href="/docs/latest/develop/interact/search-and-query/advanced-concepts/stemming/">
stemming
</a>
and
<a href="/docs/latest/develop/interact/search-and-query/advanced-concepts/stopwords/">
stop words
</a>
to improve the search even further. See this article about
<a href="https://queryunderstanding.com/tokenization-c8cdd6aef7ff">
Tokenization
</a>
for a general introduction to the concepts.
</p>
<p>
Redis Stack uses a very simple tokenizer for documents and a slightly more sophisticated tokenizer for queries. Both allow a degree of control over string escaping and tokenization.
</p>
<p>
The sections below describe the rules for tokenizing text fields and queries.
Note that
<a href="/docs/latest/develop/interact/search-and-query/advanced-concepts/tags/">
Tag fields
</a>
are essentially text fields but they use a simpler form of tokenization, as described
separately in the
<a href="#tokenization-rules-for-tag-fields">
Tokenization rules for tag fields
</a>
section.
</p>
<h2 id="tokenization-rules-for-text-fields">
Tokenization rules for text fields
</h2>
<ol>
<li>
<p>
All punctuation marks and whitespace (besides underscores) separate the document and queries into tokens. For example, any character of
<code>
,.<>{}[]"':;!@#$%^&*()-+=~
</code>
will break the text into terms, so the text
<code>
foo-bar.baz...bag
</code>
will be tokenized into
<code>
[foo, bar, baz, bag]
</code>
</p>
</li>
<li>
<p>
Escaping separators in both queries and documents is done by prepending a backslash to any separator. For example, the text
<code>
hello\-world hello-world
</code>
will be tokenized as
<code>
[hello-world, hello, world]
</code>
. In most languages you will need an extra backslash to signify an actual backslash when formatting the document or query, so the actual text entered into redis-cli will be
<code>
hello\\-world
</code>
.
</p>
</li>
<li>
<p>
Underscores (
<code>
_
</code>
) are not used as separators in either document or query, so the text
<code>
hello_world
</code>
will remain as is after tokenization.
</p>
</li>
<li>
<p>
Repeating spaces or punctuation marks are stripped.
</p>
</li>
<li>
<p>
Latin characters are converted to lowercase.
</p>
</li>
<li>
<p>
A backslash before the first digit will tokenize it as a term. This will translate the
<code>
-
</code>
sign as NOT, which otherwise would make the number negative. Add a backslash before
<code>
.
</code>
if you are searching for a float. For example,
<code>
-20 -> {-20} vs -\20 -> {NOT{20}}
</code>
.
</p>
</li>
</ol>
<h2 id="tokenization-rules-for-tag-fields">
Tokenization rules for tag fields
</h2>
<p>
<a href="/docs/latest/develop/interact/search-and-query/advanced-concepts/tags/">
Tag fields
</a>
interpret
a text field as a list of
<em>
tags
</em>
delimited by a
<a href="/docs/latest/develop/interact/search-and-query/advanced-concepts/tags/#creating-a-tag-field">
separator
</a>
character (which is a comma "," by
default). The tokenizer simply splits the text wherever it finds the separator and so most
punctuation marks and whitespace are valid characters within each tag token. The only
changes that the tokenizer makes to the tags are:
</p>
<ul>
<li>
Trimming whitespace at the start and end of the tag. Other whitespace in the tag text is left intact.
</li>
<li>
Converting Latin alphabet characters to lowercase. You can override this by adding the
<a href="/docs/latest/develop/interact/search-and-query/basic-constructs/field-and-type-options/#tag-fields">
<code>
CASESENSITIVE
</code>
</a>
option in the indexing schema for the tag field.
</li>
</ul>
<p>
This means that when you define a tag field, you don't need to escape any characters, except
in the unusual case where you want leading or trailing spaces to be part of the tag text.
However, you do need to escape certain characters in a
<em>
query
</em>
against a tag field. See
<a href="/docs/latest/develop/interact/search-and-query/advanced-concepts/query_syntax/#tag-filters">
Query syntax
</a>
for more information about this.

<h1>
Write-behind to Redis Enterprise target example
</h1>
<p>
The
<code>
redis.write
</code>
block can be used in the
<code>
output
</code>
section of the write-behind job in order to enable writing data to the Redis Enterprise target database. Multiple blocks can be used at the same time to write data to different data types. The following example captures data modified in the
<code>
address:*
</code>
keyspace, then creates a new JSON-like string field named
<code>
json_addr
</code>
, and, finally, writes the results to multiple keys in target Redis Enteprise database:

(or deleting) data previously added to the database.

Versions 6.4.2 and later support the Active-Active database controller. This controller allows you to create Redis Enterprise Active-Active databases (REAADB) and Redis Enterprise remote clusters (RERC) with custom resources. We recommend using the
<a href="/docs/latest/operate/kubernetes/active-active/create-reaadb/">
REAADB method for creating Active-Active databases
</a>
.
</div>
</div>
<p>
On Kubernetes, Redis Enterprise
<a href="/docs/latest/operate/rs/databases/active-active/">
Active-Active
</a>
databases provide read-and-write access to the same dataset from different Kubernetes clusters. For more general information about Active-Active, see the
<a href="/docs/latest/operate/rs/databases/active-active/">
Redis Enterprise Software docs
</a>
.
</p>
<p>
Creating an Active-Active database requires routing
<a href="/docs/latest/operate/kubernetes/networking/">
network access
</a>
between two Redis Enterprise clusters residing in different Kubernetes clusters. Without the proper access configured for each cluster, syncing between the databases instances will fail.
</p>
<p>
This process consists of:
</p>
<ol>
<li>
Documenting values to be used in later steps. It's important these values are correct and consistent.
</li>
<li>
Editing the Redis Enterprise cluster (REC) spec file to include the
<code>
ActiveActive
</code>
section. This will be slightly different depending on the K8s distribution you are using.
</li>
<li>
Creating the database with the
<code>
crdb-cli
</code>
command. These values must match up with values in the REC resource spec.
</li>
</ol>
<h2 id="prerequisites">
Prerequisites
</h2>
<p>
Before creating Active-Active databases, you'll need admin access to two or more working Kubernetes clusters that each have:
</p>
<ul>
<li>
Routing for external access with an
<a href="/docs/latest/operate/kubernetes/networking/ingress/">
ingress resources
</a>
(or
<a href="/docs/latest/operate/kubernetes/networking/routes/">
route resources
</a>
on OpenShift).
</li>
<li>
A working
<a href="/docs/latest/operate/kubernetes/reference/redis_enterprise_cluster_api/">
Redis Enterprise cluster (REC)
</a>
with a unique name.
</li>
<li>
Enough memory resources available for the database (see
<a href="/docs/latest/operate/rs/installing-upgrading/install/plan-deployment/hardware-requirements/">
hardware requirements
</a>
).
</li>
</ul>

The
<code>
activeActive
</code>
field and the
<code>
ingressOrRouteSpec
</code>
field cannot coexist in the same REC. If you configured your ingress via the
<code>
ingressOrRouteSpec
</code>
field in the REC, create your Active-Active database with the RedisEnterpriseActiveActiveDatabase (REAADB) custom resource.
</div>
</div>
<h2 id="document-required-parameters">
Document required parameters

<p>
The most common mistake when setting up Active-Active databases is incorrect or inconsistent parameter values. The values listed in the resource file must match those used in the crdb-cli command.

The operator uses the API hostname (

<h2 id="test-your-database">
Test your database
</h2>
<p>
The easiest way to test your Active-Active database is to set a key-value pair in one database and retrieve it from the other.
</p>
<p>
You can connect to your databases with the instructions in
<a href="/docs/latest/operate/kubernetes/re-databases/db-controller/#connect-to-a-database">
Manage databases
</a>
. Set a test key with
<code>
SET foo bar
</code>
in the first database. If your Active-Active deployment is working properly, when connected to your second database,
<code>
GET foo
</code>
should output
<code>
bar
</code>
.

<h3 id="redis-copilot">
Redis Copilot
</h3>
<p>
Redis Copilot is an AI-powered developer assistant that helps you learn about Redis, explore your Redis data, and build search queries in a conversational manner. It is available in Redis Insight as well as within the Redis public documentation.
</p>
<p>
Currently, Redis Copilot provides two primary features: a general chatbot and a context-aware data chatbot.
</p>
<p>
<strong>
General chatbot
</strong>
: the knowledge-based chatbot serves as an interactive and dynamic documentation interface to simplify the learning process. You can ask specific questions about Redis commands, concepts, and products, and get responses on the fly. The general chatbot is also available in our public docs.
</p>
<p>
<strong>
My data chatbot
</strong>
: the context-aware chatbot available in Redis Insight lets you construct search queries using everyday language rather than requiring specific programming syntax. This feature lets you query and explore data easily and interactively without extensive technical knowledge.
</p>
<p>
Here's an example of using Redis Copilot to search data using a simple, natural language prompt.
</p>
<img src="images/copilot-example.png"/>

<h2 id="tools">
Tools
</h2>
<h3 id="database-analysis">
Database analysis
</h3>
<p>
Use the database analysis tool to optimize the performance and memory usage of your Redis database. Check data type distribution and memory allocation and review the summary of key expiration time and memory to be freed over time. Inspect the top keys and namespaces sorted by consumed memory or key length and count of keys, respectively. Capture and track the changes in your database by viewing historical analysis reports. Next figure shows a sample database analysis report.
</p>
<img src="images/database_analysis.png"/>
<h3 id="redis-streams-support">
Redis Streams support
</h3>
<p>
Create and manage streams by adding, removing, and filtering entries per timestamp. To see and work with new entries, enable and customize the automatic refresh rate.
</p>
<p>
View and manage the list of consumer groups. See existing consumers in a given consumer name as well as the last messages delivered to them. Inspect the list of pending messages, explicitly acknowledge the processed items, or claim unprocessed messages via Redis Insight.
</p>
<img src="images/streams.png"/>
<h3 id="search-features">
Search features
</h3>
<p>
If you're using Redis Stack's indexing, querying, or full-text search features, Redis Insight provides UI controls to quickly and conveniently run search queries against a preselected index. You can also create a secondary index of your data in a dedicated pane.
</p>
<img src="images/search.png"/>
<h3 id="bulk-actions">
Bulk actions
</h3>
<p>
Easily and quickly delete multiple keys of the same type and/or with the same key name pattern in bulk. To do so, in the List or Tree view, set filters per key type or key names and open the Bulk Actions section. The section displays a summary of all the keys with the expected number of keys that will be deleted based on the set filters.
</p>
<p>
When the bulk deletion is completed, Redis Insight displays the results of this operation with the number of keys processed and the time taken to delete the keys in bulk.
Use bulk deletion to optimize the usage of your database based on the results from the Redis database analysis.
</p>
<img src="images/bulk_actions.png"/>
<h3 id="slow-log">
Slow Log
</h3>
<p>
The Slow Log tool displays the list of logs captured by the SLOWLOG command to analyze all commands that exceed a specified runtime, which helps with troubleshooting performance issues. Specify both the runtime and the maximum length of Slowlog (which are server configurations) to configure the list of commands logged and set the auto-refresh interval to automatically update the list of commands displayed.
</p>
<img src="images/slowlog.png"/>
<h2 id="plugins">
Plugins
</h2>
<p>
With Redis Insight you can now also extend the core functionality by building your own data visualizations. See our
<a href="https://github.com/Redis-Insight/Redis-Insight/wiki/Plugin-Documentation">

Stop words

<p class="text-lg -mt-5 mb-10">
Stop words support
</p>
<p>
Redis Stack has a default list of
<a href="https://en.wikipedia.org/wiki/Stop_words">
stop words
</a>
. These are words that are usually so common that they do not add much information to search, but take up a lot of space and CPU time in the index.
</p>
<p>
When indexing, stop words are discarded and not indexed. When searching, they are also ignored and treated as if they were not sent to the query processor. This is done when parsing the query.
</p>
<p>
At the moment, the default stop word list applies to all full-text indexes in all languages and can be overridden manually at index creation time.
</p>
<h2 id="default-stop-word-list">
Default stop word list
</h2>
<p>
The following words are treated as stop words by default:
</p>
<pre tabindex="0"><code> a, is, the, an, and, are, as, at, be, but, by, for,
if, in, into, it, no, not, of, on, or, such, that, their,
then, there, these, they, this, to, was, will, with
</code></pre>
<h2 id="overriding-the-default-stop-word-list">
Overriding the default stop word list
</h2>
<p>
Stop words for an index can be defined (or disabled completely) on index creation using the
<code>
STOPWORDS
</code>
argument with the [
<a href="/docs/latest/commands/ft.create/">
<code>
FT.CREATE
</code>
</a>
command.
</p>
<p>
The format is
<code>
STOPWORDS {number} {stopword} ...
</code>
where number is the number of stop words given. The
<code>
STOPWORDS
</code>
argument must come before the
<code>
SCHEMA
</code>
argument. For example:
</p>
<pre tabindex="0"><code>FT.CREATE myIndex STOPWORDS 3 foo bar baz SCHEMA title TEXT body TEXT
</code></pre>
<h2 id="disable-the-use-of-stop-words">
Disable the use of stop words
</h2>
<p>
Disabling stop words completely can be done by passing
<code>
STOPWORDS 0
</code>
to
<a href="/docs/latest/commands/ft.create/">
<code>
FT.CREATE
</code>
</a>
.
</p>
<h2 id="avoiding-stop-word-detection-in-search-queries">
Avoiding stop word detection in search queries
</h2>
<p>
In rare use cases, where queries are very long and are guaranteed by the client application not to contain stop words, it is possible to avoid checking for them when parsing the query. This saves some CPU time and is only worth it if the query has dozens or more terms in it. Using this without verifying that the query doesn't contain stop words might result in empty queries.

<h4 id="distributed-syncer">
Distributed Syncer
</h4>
<p>
The syncer process now supports running in a
<a href="/docs/latest/operate/rs/databases/active-active/synchronization-mode/">
distributed mode
</a>
. This option can improve the latency for Active-Active databases with a very high throughput profile. You can configure a replicated database to use distributed synchronization so that any available proxy endpoint can manage synchronization traffic.
</p>
<h4 id="disabling-rs-services-to-free-memory">
Disabling RS services to free memory
</h4>
<p>
Redis Software users can now use the REST API to
<a href="/docs/latest/operate/rs/clusters/optimize/turn-off-services/">
disable the following services
</a>
:
</p>
<ul>
<li>
cm_server
</li>
<li>
mdns_server
</li>
<li>
pdns_server

This feature can cause unintended results if the cluster relies on the disabled services.
To make sure you understand the impact of disabled services, test the system in a lab environment before you deploy in production.
</div>
</div>
<h4 id="support-for-multiple-passwords">
Support for multiple passwords
</h4>
<p>
For users of Redis 6 and RS 6.0 and above, you can now add more security to your password management by maintaining multiple passwords for a user to allow seamless password rotation.
</p>
<p>
As of RS 6.0, you can assign specific data access permissions (Redis ACLs) and cluster administration permissions to users.
Password rotation is especially helpful so that you can do a rolling update of the passwords in the application clients that connect to the Redis databases.
</p>
<p>
In this version, you can only configure multiple passwords
<a href="/docs/latest/operate/rs/security/access-control/manage-passwords/rotate-passwords/">
using the REST API
</a>
.
</p>
<h4 id="redis-modules-dependencies-management">
Redis Modules dependencies management
</h4>
<p>
RedisGears GA and RedisAI GA require Redis Software to fetch and manage external dependencies.
Modules declare dependencies at release time in their ramp file.
</p>
<p>
In this version of RS, these dependencies are installed by Redis Software when the module is added to the cluster.
The master node downloads the required dependencies and prompts the other nodes to copy the dependencies from the master node.
When all dependency requirements are satisfied, the module installation is complete.
New nodes to the cluster also automatically install the dependencies.
</p>
<h4 id="syncer-automatic-recovery-from-out-of-memory-preview-mode">
Syncer automatic recovery from out-of-memory (Preview mode)
</h4>
<p>
For Active-Active databases, the syncer process gracefully recovers from an out of memory (OOM) state.
</p>
<p>
Although Active-Active synchronization is bi-directional, in each direction we can define a source instance and a destination instance.
When a destination instance (that is, the instance running the syncer process) gets OOM, the syncer process attempts to automatically recover the data synchronization when memory becomes available.
</p>
<p>
This is a configurable option and currently under preview mode. This behavior will be GA and set as default in the next RS version.
</p>
<p>
To enable the syncer automatic recovery, do these steps on each participating cluster:
</p>
<ol>
<li>
<p>
<a href="/docs/latest/operate/rs/installing-upgrading/upgrading/upgrade-active-active/">
Upgrade the featureset version
</a>
to
<code>
3
</code>
.
</p>
</li>
<li>
<p>
Enable the syncer automatic recovery using the REST API:
</p>
<div class="highlight">
<pre class="chroma"><code class="language-sh" data-lang="sh"><span class="line"><span class="cl">curl -v -k -u <username>:<password> -X PUT -H “Content-Type: application/json” -d ‘<span class="o">{</span>crdt_syncer_auto_oom_unlatch”:true<span class="o">}</span>’ http://<cluster_address>:8080/v1/bdbs/<database_ID>
</span></span></code></pre>
</div>
</li>
</ol>
<p>
The syncer process restarts to with automatic recovery on.

Installation limitations
</h3>
<p>
Several Redis Enterprise Software installation reference files are installed to the directory
<code>
/etc/opt/redislabs/
</code>
even if you use
<a href="/docs/latest/operate/rs/installing-upgrading/install/customize-install-directories/">
custom installation directories
</a>
.
</p>
<p>
As a workaround to install Redis Enterprise Software without using any root directories, do the following before installing Redis Enterprise Software:
</p>
<ol>
<li>
<p>
Create all custom, non-root directories you want to use with Redis Enterprise Software.
</p>
</li>
<li>
<p>
Mount
<code>
/etc/opt/redislabs
</code>
to one of the custom, non-root directories.
</p>
</li>
</ol>
<h4 id="upgrade">
Upgrade
</h4>
<ul>
<li>
<a href="/docs/latest/operate/rs/release-notes/legacy-release-notes/rs-5-4-2-april-2019/">
RS 5.4.2
</a>
introduced new Active-Active Redis Database capabilities that improve its compatibility with open source Redis. Now the string data-type in Active-Active Redis Database is implicitly and dynamically typed, just like open source Redis. To use the new capabilities on nodes that are upgraded from version RS 5.4.2 or lower, you must
<a href="/docs/latest/operate/rs/installing-upgrading/upgrading/#upgrading-crdbs">
upgrade the Active-Active Redis Database protocol
</a>
.
</li>
<li>
When you upgrade an Active-Active Redis with active AOF from version
<a href="/docs/latest/operate/rs/release-notes/legacy-release-notes/rs-5-4-2-april-2019/">
RS 5.4.2
</a>
or earlier to version
<a href="/docs/latest/operate/rs/release-notes/legacy-release-notes/rs-5-4-4-june-2019/">
RS 5.4.4
</a>
or later:
<ul>
<li>
If replication is enabled, you must run the BGREWRITEAOF command on all replica shards after the upgrade.
</li>
<li>
If replication is not enabled, you must run the BGREWRITEAOF command on all shards after the upgrade.
</li>
</ul>
</li>
<li>
Node upgrade fails if the SSL certificates were configured in version 5.0.2 or above by manually updating the certificates on the disk instead of
<a href="/docs/latest/operate/rs/security/certificates/updating-certificates/">
updating them through the API
</a>
. For assistance with this issue, contact Support.
</li>
<li>
Starting from
<a href="/docs/latest/operate/rs/release-notes/legacy-release-notes/rs-5-4-2-april-2019/">
RS 5.4.2
</a>
, to preserve the current Redis major.minor version during database upgrade you must use the keep_redis_version option instead of keep_current_version.
</li>
</ul>
<h4 id="redis-commands">
Redis commands
</h4>
<ul>
<li>
The capability of disabling specific Redis commands does not work on commands specific to Redis modules.
</li>
<li>
CLIENT UNBLOCK command is not supported in RS 5.4 and above
</li>
<li>
Starting from RS 5.4.2 and after upgrading the CRDB, TYPE commands for string data-type in CRDBs return "string" (OSS Redis standard).
</li>

The
<code>
SCAN
</code>
command and the closely related commands
<a href="/docs/latest/commands/sscan/">
<code>
SSCAN
</code>
</a>
,
<a href="/docs/latest/commands/hscan/">
<code>
HSCAN
</code>
</a>
and
<a href="/docs/latest/commands/zscan/">
<code>
ZSCAN
</code>
</a>
are used in order to incrementally iterate over a collection of elements.
</p>
<ul>
<li>
<code>
SCAN
</code>
iterates the set of keys in the currently selected Redis database.
</li>
<li>
<a href="/docs/latest/commands/sscan/">
<code>
SSCAN
</code>
</a>
iterates elements of Sets types.
</li>
<li>
<a href="/docs/latest/commands/hscan/">
<code>
HSCAN
</code>
</a>
iterates fields of Hash types and their associated values.
</li>
<li>
<a href="/docs/latest/commands/zscan/">
<code>
ZSCAN
</code>
</a>
iterates elements of Sorted Set types and their associated scores.
</li>
</ul>
<p>
Since these commands allow for incremental iteration, returning only a small number of elements per call, they can be used in production without the downside of commands like
<a href="/docs/latest/commands/keys/">
<code>
KEYS
</code>
</a>
or
<a href="/docs/latest/commands/smembers/">
<code>
SMEMBERS
</code>
</a>
that may block the server for a long time (even several seconds) when called against big collections of keys or elements.
</p>
<p>
However while blocking commands like
<a href="/docs/latest/commands/smembers/">
<code>
SMEMBERS
</code>
</a>
are able to provide all the elements that are part of a Set in a given moment, The SCAN family of commands only offer limited guarantees about the returned elements since the collection that we incrementally iterate can change during the iteration process.
</p>
<p>
Note that
<code>
SCAN
</code>
,
<a href="/docs/latest/commands/sscan/">
<code>
SSCAN
</code>
</a>
,
<a href="/docs/latest/commands/hscan/">
<code>
HSCAN
</code>
</a>
and
<a href="/docs/latest/commands/zscan/">
<code>
ZSCAN
</code>
</a>
all work very similarly, so this documentation covers all four commands. However an obvious difference is that in the case of
<a href="/docs/latest/commands/sscan/">
<code>
SSCAN
</code>
</a>
,
<a href="/docs/latest/commands/hscan/">
<code>
HSCAN
</code>
</a>
and
<a href="/docs/latest/commands/zscan/">
<code>
ZSCAN
</code>
</a>
the first argument is the name of the key holding the Set, Hash or Sorted Set value. The
<code>
SCAN
</code>
command does not need any key name argument as it iterates keys in the current database, so the iterated object is the database itself.
</p>
<h2 id="scan-basic-usage">
SCAN basic usage
</h2>
<p>
SCAN is a cursor based iterator. This means that at every call of the command, the server returns an updated cursor that the user needs to use as the cursor argument in the next call.
</p>
<p>
An iteration starts when the cursor is set to 0, and terminates when the cursor returned by the server is 0. The following is an example of SCAN iteration:
</p>
<pre tabindex="0"><code>> scan 0
1) "17"
2) 1) "key:12"
2) "key:8"
3) "key:4"
4) "key:14"
5) "key:16"
6) "key:17"
7) "key:15"
8) "key:10"
9) "key:3"
10) "key:7"
11) "key:1"
> scan 17
1) "0"
2) 1) "key:5"
2) "key:18"
3) "key:0"
4) "key:2"
5) "key:19"
6) "key:13"
7) "key:6"
8) "key:9"
9) "key:11"
</code></pre>
<p>
In the example above, the first call uses zero as a cursor, to start the iteration. The second call uses the cursor returned by the previous call as the first element of the reply, that is, 17.
</p>
<p>
As you can see the
<strong>
SCAN return value
</strong>
is an array of two values: the first value is the new cursor to use in the next call, the second value is an array of elements.
</p>
<p>
Since in the second call the returned cursor is 0, the server signaled to the caller that the iteration finished, and the collection was completely explored. Starting an iteration with a cursor value of 0, and calling
<code>
SCAN
</code>
until the returned cursor is 0 again is called a
<strong>
full iteration
</strong>
.
</p>

<a href="/docs/latest/commands/sscan/">
<code>

<a href="/docs/latest/commands/hscan/">
<code>

</a>
and
<a href="/docs/latest/commands/zscan/">
<code>

</a>
return a two element multi-bulk reply, where the first element is a string representing an unsigned 64 bit number (the cursor), and the second element is a multi-bulk with an array of elements.
</p>
<ul>
<li>

</li>

</li>
</ul>
<h2 id="scan-guarantees">
Scan guarantees
</h2>
<p>
The
<code>
SCAN
</code>
command, and the other commands in the
<code>
SCAN
</code>
family, are able to provide to the user a set of guarantees associated to full iterations.
</p>
<ul>
<li>
A full iteration always retrieves all the elements that were present in the collection from the start to the end of a full iteration. This means that if a given element is inside the collection when an iteration is started, and is still there when an iteration terminates, then at some point
<code>
SCAN
</code>
returned it to the user.
</li>
<li>
A full iteration never returns any element that was NOT present in the collection from the start to the end of a full iteration. So if an element was removed before the start of an iteration, and is never added back to the collection for all the time an iteration lasts,
<code>
SCAN
</code>
ensures that this element will never be returned.
</li>
</ul>
<p>
However because
<code>
SCAN
</code>
has very little state associated (just the cursor) it has the following drawbacks:
</p>
<ul>
<li>
A given element may be returned multiple times. It is up to the application to handle the case of duplicated elements, for example only using the returned elements in order to perform operations that are safe when re-applied multiple times.
</li>
<li>
Elements that were not constantly present in the collection during a full iteration, may be returned or not: it is undefined.
</li>
</ul>
<h2 id="number-of-elements-returned-at-every-scan-call">
Number of elements returned at every SCAN call
</h2>
<p>
<code>
SCAN
</code>
family functions do not guarantee that the number of elements returned per call are in a given range. The commands are also allowed to return zero elements, and the client should not consider the iteration complete as long as the returned cursor is not zero.
</p>
<p>
However the number of returned elements is reasonable, that is, in practical terms
<code>
SCAN
</code>
may return a maximum number of elements in the order of a few tens of elements when iterating a large collection, or may return all the elements of the collection in a single call when the iterated collection is small enough to be internally represented as an encoded data structure (this happens for small Sets, Hashes and Sorted Sets).
</p>
<p>
However there is a way for the user to tune the order of magnitude of the number of returned elements per call using the
<strong>
COUNT
</strong>
option.
</p>
<h2 id="the-count-option">
The COUNT option
</h2>
<p>
While
<code>
SCAN
</code>
does not provide guarantees about the number of elements returned at every iteration, it is possible to empirically adjust the behavior of
<code>
SCAN
</code>
using the
<strong>
COUNT
</strong>
option. Basically with COUNT the user specifies the
<em>
amount of work that should be done at every call in order to retrieve elements from the collection
</em>
. This is
<strong>
just a hint
</strong>
for the implementation, however generally speaking this is what you could expect most of the times from the implementation.
</p>
<ul>
<li>
The default
<code>
COUNT
</code>
value is 10.
</li>
<li>
When iterating the key space, or a Set, Hash or Sorted Set that is big enough to be represented by a hash table, assuming no
<strong>
MATCH
</strong>
option is used, the server will usually return
<em>
count
</em>
or a few more than
<em>
count
</em>
elements per call. Please check the
<em>
why SCAN may return all the elements at once
</em>
section later in this document.
</li>
<li>
When iterating Sets encoded as intsets (small sets composed of just integers), or Hashes and Sorted Sets encoded as ziplists (small hashes and sets composed of small individual values), usually all the elements are returned in the first
<code>
SCAN
</code>
call regardless of the
<code>
COUNT
</code>
value.
</li>
</ul>
<p>
Important:
<strong>
there is no need to use the same COUNT value
</strong>
for every iteration. The caller is free to change the count from one iteration to the other as required, as long as the cursor passed in the next call is the one obtained in the previous call to the command.
</p>
<h2 id="the-match-option">
The MATCH option
</h2>
<p>
It is possible to only iterate elements matching a given glob-style pattern, similarly to the behavior of the
<a href="/docs/latest/commands/keys/">
<code>
KEYS
</code>
</a>
command that takes a pattern as its only argument.
</p>
<p>
To do so, just append the
<code>
MATCH <pattern>
</code>
arguments at the end of the
<code>
SCAN
</code>
command (it works with all the
<code>
SCAN
</code>
family commands).
</p>
<p>
This is an example of iteration using
<strong>
MATCH

It is important to note that the
<strong>
MATCH
</strong>
filter is applied after elements are retrieved from the collection, just before returning data to the client. This means that if the pattern matches very little elements inside the collection,
<code>
SCAN
</code>
will likely return no elements in most iterations. An example is shown below:

<p>
As you can see most of the calls returned zero elements, but the last call where a
<code>
COUNT
</code>
of 1000 was used in order to force the command to do more scanning for that iteration.
</p>
<p>
When using
<a href="/docs/latest/operate/oss_and_stack/management/scaling/">
Redis Cluster
</a>
, the search is optimized for patterns that imply a single slot.
If a pattern can only match keys of one slot,
Redis only iterates over keys in that slot, rather than the whole database,
when searching for keys matching the pattern.
For example, with the pattern
<code>
{a}h*llo
</code>
, Redis would only try to match it with the keys in slot 15495, which hash tag
<code>
{a}
</code>
implies.
To use pattern with hash tag, see
<a href="/docs/latest/operate/oss_and_stack/reference/cluster-spec#hash-tags">
Hash tags
</a>
in the Cluster specification for more information.
</p>
<h2 id="the-type-option">
The TYPE option
</h2>
<p>
You can use the
<code>
TYPE
</code>
option to ask
<code>
SCAN
</code>
to only return objects that match a given
<code>
type
</code>
, allowing you to iterate through the database looking for keys of a specific type. The
<strong>
TYPE
</strong>
option is only available on the whole-database
<code>
SCAN
</code>
, not
<a href="/docs/latest/commands/hscan/">
<code>
HSCAN
</code>
</a>
or
<a href="/docs/latest/commands/zscan/">
<code>
ZSCAN
</code>
</a>
etc.
</p>
<p>
The
<code>
type
</code>
argument is the same string name that the
<a href="/docs/latest/commands/type/">
<code>
TYPE
</code>
</a>
command returns. Note a quirk where some Redis types, such as GeoHashes, HyperLogLogs, Bitmaps, and Bitfields, may internally be implemented using other Redis types, such as a string or zset, so can't be distinguished from other keys of that same type by
<code>
SCAN
</code>
. For example, a ZSET and GEOHASH:

<p>
It is important to note that the
<strong>
TYPE
</strong>
filter is also applied after elements are retrieved from the database, so the option does not reduce the amount of work the server has to do to complete a full iteration, and for rare types you may receive no elements in many iterations.

<h2 id="the-novalues-option">
The NOVALUES option
</h2>
<p>
When using
<a href="/docs/latest/commands/hscan/">
<code>
HSCAN
</code>
</a>
, you can use the
<code>
NOVALUES
</code>
option to make Redis return only the keys in the hash table without their corresponding values.

<h2 id="multiple-parallel-iterations">
Multiple parallel iterations
</h2>
<p>
It is possible for an infinite number of clients to iterate the same collection at the same time, as the full state of the iterator is in the cursor, that is obtained and returned to the client at every call. No server side state is taken at all.
</p>
<h2 id="terminating-iterations-in-the-middle">
Terminating iterations in the middle
</h2>
<p>
Since there is no state server side, but the full state is captured by the cursor, the caller is free to terminate an iteration half-way without signaling this to the server in any way. An infinite number of iterations can be started and never terminated without any issue.
</p>
<h2 id="calling-scan-with-a-corrupted-cursor">
Calling SCAN with a corrupted cursor
</h2>
<p>
Calling
<code>
SCAN
</code>
with a broken, negative, out of range, or otherwise invalid cursor, will result in undefined behavior but never in a crash. What will be undefined is that the guarantees about the returned elements can no longer be ensured by the
<code>
SCAN
</code>
implementation.
</p>
<p>
The only valid cursors to use are:
</p>
<ul>
<li>
The cursor value of 0 when starting an iteration.
</li>
<li>
The cursor returned by the previous call to SCAN in order to continue the iteration.
</li>
</ul>
<h2 id="guarantee-of-termination">
Guarantee of termination
</h2>
<p>
The
<code>
SCAN
</code>
algorithm is guaranteed to terminate only if the size of the iterated collection remains bounded to a given maximum size, otherwise iterating a collection that always grows may result into
<code>
SCAN
</code>
to never terminate a full iteration.
</p>
<p>
This is easy to see intuitively: if the collection grows there is more and more work to do in order to visit all the possible elements, and the ability to terminate the iteration depends on the number of calls to
<code>
SCAN
</code>
and its COUNT option value compared with the rate at which the collection grows.
</p>
<h2 id="why-scan-may-return-all-the-items-of-an-aggregate-data-type-in-a-single-call">
Why SCAN may return all the items of an aggregate data type in a single call?
</h2>
<p>
In the
<code>
COUNT
</code>
option documentation, we state that sometimes this family of commands may return all the elements of a Set, Hash or Sorted Set at once in a single call, regardless of the
<code>
COUNT
</code>
option value. The reason why this happens is that the cursor-based iterator can be implemented, and is useful, only when the aggregate data type that we are scanning is represented as a hash table. However Redis uses a
<a href="/docs/latest/operate/oss_and_stack/management/optimization/memory-optimization/">
memory optimization
</a>
where small aggregate data types, until they reach a given amount of items or a given max size of single elements, are represented using a compact single-allocation packed encoding. When this is the case,
<code>
SCAN
</code>
has no meaningful cursor to return, and must iterate the whole data structure at once, so the only sane behavior it has is to return everything in a call.
</p>
<p>
However once the data structures are bigger and are promoted to use real hash tables, the
<code>
SCAN
</code>
family of commands will resort to the normal behavior. Note that since this special behavior of returning all the elements is true only for small aggregates, it has no effects on the command complexity or latency. However the exact limits to get converted into real hash tables are
<a href="/docs/latest/operate/oss_and_stack/management/optimization/memory-optimization/">
user configurable
</a>
, so the maximum number of elements you can see returned in a single call depends on how big an aggregate data type could be and still use the packed representation.
</p>
<p>
Also note that this behavior is specific of
<a href="/docs/latest/commands/sscan/">
<code>
SSCAN
</code>
</a>
,
<a href="/docs/latest/commands/hscan/">
<code>
HSCAN
</code>
</a>
and
<a href="/docs/latest/commands/zscan/">
<code>
ZSCAN
</code>
</a>
.
<code>
SCAN
</code>
itself never shows this behavior because the key space is always represented by hash tables.

<h2 id="creating-triggers">
Creating triggers
</h2>
<p>
Functions within Redis can respond to events using keyspace triggers. While the majority of these events are initiated by command invocations, they also include events that occur when a key expires or is removed from the database.
</p>
<p>
For the full list of supported events, please refer to the
<a href="/docs/latest/develop/use/keyspace-notifications#events-generated-by-different-commands/?utm_source=redis&utm_medium=app&utm_campaign=redisinsight_triggers_and_functions_guide">
Redis keyspace notifications page
</a>
.
</p>
<p>
The following code creates a new keyspace trigger that adds a new field to a new or updated hash with the latest update time.
</p>
<p>
Load the code in your database:
</p>
<pre tabindex="0"><code class="language-redis" data-lang="redis">TFUNCTION LOAD REPLACE "#!js name=myFirstLibrary api_version=1.0\n
function addLastUpdatedField(client, data) {
if(data.event == 'hset') {
var currentDateTime = Date.now();
client.call('hset', data.key, 'last_updated', currentDateTime.toString());
}
}
redis.registerKeySpaceTrigger('addLastUpdated', 'fellowship:', addLastUpdatedField);" // Register the KeySpaceTrigger 'AddLastUpdated' for keys with the prefix 'fellowship' with a callback to the function 'addLastUpdatedField'
</code></pre>
<p>
Add a new hash with the required prefix to trigger our function.
</p>
<div class="highlight">
<pre class="chroma"><code class="language-Shell" data-lang="Shell"><span class="line"><span class="cl">127.0.0.1:6379> HSET fellowship:1 name <span class="s2">"Frodo Baggins"</span> title <span class="s2">"The One Ring Bearer"</span>

<p>
Due to an OpenSSL 1.1 compatibility issue between modules and clusters, Redis Enterprise Software version 7.4.2-54 is not fully supported on Amazon Linux 2 clusters with databases that use the following modules: RedisGears, RediSearch, or RedisTimeSeries.

<p>
You cannot upgrade from a prior RHEL version to RHEL 9 if the Redis Enterprise cluster contains a RedisGraph module, even if unused by any database. The

Open source Redis security fixes compatibility
</h4>
<p>
As part of Redis's commitment to security, Redis Enterprise Software implements the latest
<a href="https://github.com/redis/redis/releases">
security fixes
</a>
available with
<a href="https://github.com/redis/redis">
open source Redis
</a>
. Redis Enterprise has already included the fixes for the relevant CVEs.
</p>
<p>
Some CVEs announced for open source Redis do not affect Redis Enterprise due to different or additional functionality available in Redis Enterprise that is not available in open source Redis.
</p>
<p>
Redis Enterprise 7.4.2-54 supports open source Redis 7.2, 6.2, and 6.0. Below is the list of open source Redis CVEs fixed by version.
</p>
<p>
Redis 7.2.x:
</p>
<ul>
<li>
<p>
(CVE-2023-41056) In some cases, Redis may incorrectly handle resizing of memory buffers, which can result in incorrect accounting of buffer sizes and lead to heap overflow and potential remote code execution.
</p>
</li>
<li>
<p>
(CVE-2023-41053) Redis does not correctly identify keys accessed by
<code>
SORT_RO
</code>
and, as a result, may grant users executing this command access to keys that are not explicitly authorized by the ACL configuration. (Redis 7.2.1)
</p>
</li>
</ul>
<p>
Redis 7.0.x:
</p>
<ul>
<li>
<p>
(CVE-2023-41056) In some cases, Redis may incorrectly handle resizing of memory buffers, which can result in incorrect accounting of buffer sizes and lead to heap overflow and potential remote code execution.

(CVE-2023-41053) Redis does not correctly identify keys accessed by

Action object
</h1>
<p class="text-lg -mt-5 mb-10">
An object that represents cluster actions
</p>
<p>
The cluster allows you to invoke general maintenance actions such as rebalancing or taking a node offline by moving all of its entities to other nodes.
</p>
<p>
Actions are implemented as tasks in the cluster. Every task has a unique
<code>
task_id
</code>
assigned by the cluster, a task name which describes the task, a status, and additional task-specific parameters.
</p>
<p>
The REST API provides a simplified interface that allows callers to invoke actions and query their status without a specific
<code>
task_id
</code>
.
</p>
<p>
The action lifecycle is based on the following status and status transitions:

<p>
The actual number of samples returned by a
<code>
GET stats
</code>
request depends on how many samples are available and any filters applied by the optional URL parameters. For example, newly created objects (clusters, nodes, databases, or shards) or a narrow time filter range will return fewer samples.

To reduce load generated by stats collection, relatively inactive databases or shards (less than 5 ops/sec) do not collect 1sec stats at one second intervals. Instead, they collect 1sec stats every 2-5 seconds but still retain the same maximum number of samples.

<h1>
Field and type options
</h1>
<p class="text-lg -mt-5 mb-10">
Available field types and options.
</p>
<p>
Redis Stack provides various field types that allow you to store and search different kinds of data in your indexes. This page explains the available field types, their characteristics, and how they can be used effectively.
</p>
<h2 id="numeric-fields">
Numeric fields
</h2>
<p>
Numeric fields are used to store non-textual, countable values. They can hold integer or floating-point values. Numeric fields are sortable, meaning you can perform range-based queries and retrieve documents based on specific numeric conditions. For example, you can search for documents with a price between a certain range or retrieve documents with a specific rating value.
</p>
<p>
You can add number fields to a schema in
<a href="/docs/latest/commands/ft.create/">
<code>
FT.CREATE
</code>
</a>
using this syntax:
</p>
<pre tabindex="0"><code>FT.CREATE ... SCHEMA ... {field_name} NUMERIC [SORTABLE] [NOINDEX]
</code></pre>
<p>
where:
</p>
<ul>
<li>
<code>
SORTABLE
</code>
indicates that the field can be sorted. This is useful for performing range queries and sorting search results based on numeric values.
</li>
<li>
<code>
NOINDEX
</code>
indicates that the field is not indexed. This is useful for storing numeric values that you don't want to search for, but that you want to retrieve in search results.
</li>
</ul>
<p>
You can search for documents with specific numeric values using the
<code>
@<field_name>:[<min> <max>]
</code>
query syntax. For example, this query finds documents with a price between 200 and 300:
</p>
<pre tabindex="0"><code>FT.SEARCH products "@price:[200 300]"
</code></pre>
<p>
You can also use the following query syntax to perform more complex numeric queries:

</p>
<h2 id="geo-fields">
Geo fields
</h2>
<p>
Geo fields are used to store geographical coordinates such as longitude and latitude. They enable geospatial radius queries, which allow you to implement location-based search functionality in your applications such as finding nearby restaurants, stores, or any other points of interest.
</p>
<p>
You can add geo fields to the schema in
<a href="/docs/latest/commands/ft.create/">
<code>
FT.CREATE
</code>
</a>
using this syntax:
</p>
<pre tabindex="0"><code>FT.CREATE ... SCHEMA ... {field_name} GEO [SORTABLE] [NOINDEX]
</code></pre>
<p>
Where:
</p>
<ul>
<li>
<code>
SORTABLE
</code>
indicates that the field can be sorted. This is useful for performing range queries and sorting search results based on coordinates.
</li>
<li>
<code>
NOINDEX
</code>
indicates that the field is not indexed. This is useful for storing coordinates that you don't want to search for, but that you still want to retrieve in search results.
</li>
</ul>
<p>
You can query geo fields using the
<code>
@<field_name>:[<lon> <lat> <radius> <unit>]
</code>
query syntax. For example, this query finds documents within 1000 kilometers from the point
<code>
2.34, 48.86
</code>
:
</p>
<pre tabindex="0"><code>FT.SEARCH cities "@coords:[2.34 48.86 1000 km]"
</code></pre>
<h2 id="vector-fields">
Vector fields
</h2>
<p>
Vector fields are floating-point vectors that are typically generated by external machine learning models. These vectors represent unstructured data such as text, images, or other complex features. Redis Stack allows you to search for similar vectors using vector search algorithms like cosine similarity, Euclidean distance, and inner product. This enables you to build advanced search applications, recommendation systems, or content similarity analysis.

<pre tabindex="0"><code>FT.CREATE ... SCHEMA ... {field_name} VECTOR {algorithm} {count} [{attribute_name} {attribute_value} ...]
</code></pre>
<p>
Where:
</p>
<ul>
<li>
<p>
<code>
{algorithm}
</code>
must be specified and be a supported vector similarity index algorithm. The supported algorithms are:
</p>
<ul>
<li>
<code>
FLAT
</code>
: brute force algorithm.
</li>
<li>
<code>
HNSW
</code>
: hierarchical, navigable, small world algorithm.
</li>
</ul>
<p>
The
<code>
{algorithm}
</code>
attribute specifies the algorithm to use when searching
<code>
k
</code>
most similar vectors in the index or filtering vectors by range.
</p>
</li>
<li>
<p>
<code>
{count}
</code>
specifies the number of attributes for the index and it must be present.
Notice that
<code>
{count}
</code>
represents the total number of attribute pairs passed in the command. Algorithm parameters should be submitted as named arguments.
</p>
<p>
For example:
</p>
<pre tabindex="0"><code>FT.CREATE my_idx SCHEMA vec_field VECTOR FLAT 6 TYPE FLOAT32 DIM 128 DISTANCE_METRIC L2
</code></pre>
<p>
Here, three parameters are passed for the index (
<a href="/docs/latest/commands/type/">
<code>
TYPE
</code>
</a>
,
<code>
DIM
</code>
,
<code>
DISTANCE_METRIC
</code>
), and
<code>
count
</code>
is the total number of attributes (6).
</p>
</li>
<li>
<p>
<code>
{attribute_name} {attribute_value}
</code>
are algorithm attributes for the creation of the vector index. Every algorithm has its own mandatory and optional attributes.
</p>
</li>
</ul>

Tag fields
</h2>
<p>
Tag fields are used to store textual data that represents a collection of data tags or labels. Tag fields are characterized by their low cardinality, meaning they typically have a limited number of distinct values. Unlike text fields, tag fields are stored as-is without tokenization or stemming. They are useful for organizing and categorizing data, making it easier to filter and retrieve documents based on specific tags.
</p>
<p>
Tag fields can be added to the schema with the following syntax:
</p>
<pre tabindex="0"><code>FT.CREATE ... SCHEMA ... {field_name} TAG [SEPARATOR {sep}] [CASESENSITIVE]
</code></pre>
<p>
where
</p>
<ul>
<li>
<p>
<code>
SEPARATOR
</code>
defaults to a comma (
<code>
,
</code>
), and can be any printable ASCII character. It is used to separate tags in the field value. For example, if the field value is
<code>
hello,world
</code>
, the tags are
<code>
hello
</code>
and
<code>
world
</code>
.
</p>
</li>
<li>
<p>
<code>
CASESENSITIVE
</code>
indicates that the field is case-sensitive. By default, tag fields are case-insensitive.
</p>
</li>
</ul>
<p>
You can search for documents with specific tags using the
<code>
@<field_name>:{<tag>}
</code>
query syntax. For example, this query finds documents with the tag
<code>
blue
</code>
:
</p>
<pre tabindex="0"><code>FT.SEARCH idx "@tags:{blue}"
</code></pre>
<p>
For more information about tag fields, see
<a href="/docs/latest/develop/interact/search-and-query/advanced-concepts/tags/">
Tag Fields
</a>
.
</p>
<h2 id="text-fields">
Text fields
</h2>
<p>
Text fields are specifically designed for storing human language text. When indexing text fields, Redis Stack performs several transformations to optimize search capabilities. The text is transformed to lowercase, allowing case-insensitive searches. The data is tokenized, meaning it is split into individual words or tokens, which enables efficient full-text search functionality. Text fields can be weighted to assign different levels of importance to specific fields during search operations. Additionally, text fields can be sorted based on their values, enabling the sorting of search results by relevance or other criteria.
</p>
<p>
Text fields can be added to the schema with the following syntax:
</p>
<pre tabindex="0"><code>FT.CREATE ... SCHEMA ... {field_name} TEXT [WEIGHT] [NOSTEM] [PHONETIC {matcher}] [SORTABLE] [NOINDEX] [WITHSUFFIXTRIE]
</code></pre>
<p>
where
</p>
<ul>
<li>
<p>
<code>
WEIGHT
</code>
indicates that the field is weighted. This is useful for assigning different levels of importance to specific fields during search operations.
</p>
</li>
<li>
<p>
<code>
NOSTEM
</code>
indicates that the field is not stemmed. This is useful for storing text that you don't want to be tokenized, such as URLs or email addresses.
</p>
</li>
<li>
<p>
<code>
PHONETIC {matcher}
</code>
Declaring a text attribute as
<code>
PHONETIC
</code>
will perform phonetic matching on it in searches by default. The obligatory matcher argument specifies the phonetic algorithm and language used. The following matchers are supported:
</p>
<ul>
<li>
<code>
dm:en
</code>
- double metaphone for English
</li>
<li>
<code>
dm:fr
</code>
- double metaphone for French
</li>
<li>
<code>
dm:pt
</code>
- double metaphone for Portuguese
</li>
<li>
<code>
dm:es
</code>
- double metaphone for Spanish
</li>
</ul>
<p>
For more information, see
<a href="/docs/latest/develop/interact/search-and-query/advanced-concepts/phonetic_matching/">
Phonetic Matching
</a>
.
</p>
</li>
<li>
<p>
<code>
SORTABLE
</code>
indicates that the field can be sorted. This is useful for performing range queries and sorting search results based on text values.
</p>
</li>
<li>
<p>
<code>
NOINDEX
</code>
indicates that the field is not indexed. This is useful for storing text that you don't want to search for, but that you still want to retrieve in search results.
</p>
</li>
<li>
<p>
<code>
WITHSUFFIXTRIE
</code>
indicates that the field will be indexed with a suffix trie. The index will keep a suffix trie with all terms which match the suffix. It is used to optimize
<code>
contains (*foo*)
</code>
and
<code>
suffix (*foo)
</code>
queries. Otherwise, a brute-force search on the trie is performed. If a suffix trie exists for some fields, these queries will be disabled for other fields.
</p>
</li>
</ul>
<p>
You can search for documents with specific text values using the
<code>
<term>
</code>
or the
<code>
@<field_name>:{<term>}
</code>
query syntax. Here are a couple of examples:
</p>
<ul>
<li>
<p>
Search for a term in every text attribute:
</p>
<pre tabindex="0"><code>FT.SEARCH books-idx "wizard"
</code></pre>
</li>
<li>
<p>
Search for a term only in the
<code>
title
</code>
attribute
</p>
<pre tabindex="0"><code>FT.SEARCH books-idx "@title:dogs"
</code></pre>
</li>
</ul>

Atomically returns and removes the first/last element (head/tail depending on

, and pushes the
element at the first/last element (head/tail depending on the

.
</p>
<p>
For example: consider

a,b,c
</code>
, and
<code>
destination
</code>
holding the list
<code>
x,y,z

.
Executing
<code>

results in

</p>
<p>
If

is returned and no operation is
performed.
If
<code>
source
</code>
and
<code>
destination
</code>
are the same, the operation is equivalent to
removing the first/last element from the list and pushing it as first/last
element of the list, so it can be considered as a list rotation command (or a

<h2 id="pattern-reliable-queue">
Pattern: Reliable queue
</h2>
<p>
Redis is often used as a messaging server to implement processing of background
jobs or other kinds of messaging tasks.
A simple form of queue is often obtained pushing values into a list in the
producer side, and waiting for this values in the consumer side using
<a href="/docs/latest/commands/rpop/">
<code>
RPOP
</code>
</a>
(using polling), or
<a href="/docs/latest/commands/brpop/">
<code>
BRPOP
</code>
</a>
if the client is better served by a blocking
operation.
</p>
<p>
However in this context the obtained queue is not
<em>
reliable
</em>
as messages can
be lost, for example in the case there is a network problem or if the consumer
crashes just after the message is received but it is still to process.
</p>
<p>
<code>
LMOVE
</code>
(or
<a href="/docs/latest/commands/blmove/">
<code>
BLMOVE
</code>
</a>
for the blocking variant) offers a way to avoid
this problem: the consumer fetches the message and at the same time pushes it
into a
<em>
processing
</em>
list.
It will use the
<a href="/docs/latest/commands/lrem/">
<code>
LREM
</code>
</a>
command in order to remove the message from the
<em>
processing
</em>
list once the message has been processed.
</p>
<p>
An additional client may monitor the
<em>
processing
</em>
list for items that remain
there for too much time, and will push those timed out items into the queue
again if needed.
</p>
<h2 id="pattern-circular-list">
Pattern: Circular list
</h2>
<p>
Using
<code>
LMOVE
</code>
with the same source and destination key, a client can visit
all the elements of an N-elements list, one after the other, in O(N) without
transferring the full list from the server to the client using a single
<a href="/docs/latest/commands/lrange/">
<code>
LRANGE
</code>
</a>
operation.
</p>
<p>
The above pattern works even in the following conditions:
</p>
<ul>
<li>
There are multiple clients rotating the list: they'll fetch different
elements, until all the elements of the list are visited, and the process
restarts.
</li>
<li>
Even if other clients are actively pushing new items at the end of the list.
</li>
</ul>
<p>
The above makes it very simple to implement a system where a set of items must
be processed by N workers continuously as fast as possible.
An example is a monitoring system that must check that a set of web sites are
reachable, with the smallest delay possible, using a number of parallel workers.
</p>

Note that this implementation of workers is trivially scalable and reliable,
because even if a message is lost the item is still in the queue and will be
processed at the next iteration.

When all the elements in a sorted set are inserted with the same score, in order to force lexicographical ordering, this command returns all the elements in the sorted set at
<code>
key
</code>
with a value between
<code>
min
</code>
and
<code>
max
</code>
.
</p>
<p>
If the elements in the sorted set have different scores, the returned elements are unspecified.
</p>
<p>
The elements are considered to be ordered from lower to higher strings as compared byte-by-byte using the
<code>
memcmp()
</code>
C function. Longer strings are considered greater than shorter strings if the common part is identical.
</p>
<p>
The optional
<code>
LIMIT
</code>
argument can be used to only get a range of the matching
elements (similar to
<em>
SELECT LIMIT offset, count
</em>
in SQL). A negative
<code>
count
</code>
returns all elements from the
<code>
offset
</code>
.
Keep in mind that if
<code>
offset
</code>
is large, the sorted set needs to be traversed for
<code>
offset
</code>
elements before getting to the elements to return, which can add up to
O(N) time complexity.

<h2 id="how-to-specify-intervals">
How to specify intervals
</h2>
<p>
Valid
<em>
start
</em>
and
<em>
stop
</em>
must start with
<code>
(
</code>
or
<code>
[
</code>
, in order to specify
if the range item is respectively exclusive or inclusive.
The special values of
<code>
+
</code>
or
<code>
-
</code>
for
<em>
start
</em>
and
<em>
stop
</em>
have the special
meaning or positively infinite and negatively infinite strings, so for
instance the command
<strong>
ZRANGEBYLEX myzset - +
</strong>
is guaranteed to return
all the elements in the sorted set, if all the elements have the same
score.
</p>
<h2 id="details-on-strings-comparison">
Details on strings comparison
</h2>
<p>
Strings are compared as binary array of bytes. Because of how the ASCII character
set is specified, this means that usually this also have the effect of comparing
normal ASCII characters in an obvious dictionary way. However this is not true
if non plain ASCII strings are used (for example utf8 strings).
</p>
<p>
However the user can apply a transformation to the encoded string so that
the first part of the element inserted in the sorted set will compare as the
user requires for the specific application. For example if I want to
add strings that will be compared in a case-insensitive way, but I still
want to retrieve the real case when querying, I can add strings in the
following way:
</p>
<pre><code>ZADD autocomplete 0 foo:Foo 0 bar:BAR 0 zap:zap
</code></pre>
<p>
Because of the first
<em>
normalized
</em>
part in every element (before the colon character), we are forcing a given comparison, however after the range is queries using
<code>
ZRANGEBYLEX
</code>
the application can display to the user the second part of the string, after the colon.
</p>
<p>
The binary nature of the comparison allows to use sorted sets as a general
purpose index, for example the first part of the element can be a 64 bit
big endian number: since big endian numbers have the most significant bytes
in the initial positions, the binary comparison will match the numerical
comparison of the numbers. This can be used in order to implement range
queries on 64 bit values. As in the example below, after the first 8 bytes
we can store the value of the element we are actually indexing.

<h1>
Prepare SQL Server for RDI
</h1>
<p class="text-lg -mt-5 mb-10">
Prepare SQL Server databases to work with RDI
</p>
<p>
To prepare your SQL Server database for Debezium, you must first run a query to
enable CDC globally and then separately enable CDC for each table you want to
capture. You need administrator privileges to do this.
</p>
<p>
Once you enable CDC, it captures all of the INSERT, UPDATE, and DELETE operations
on your chosen tables. The Debezium connector can then emit these events to
<a href="https://kafka.apache.org/intro#intro_concepts_and_terms">
Kafka topics
</a>
.
</p>
<h2 id="1-enable-cdc-on-the-database">
1. Enable CDC on the database
</h2>
<p>
There are two system stored procedures to enable CDC (you need
administrator privileges to run these). Use
<code>
sys.sp_cdc_enable_db
</code>
to enable CDC for the whole database and then
You can run the procedure with SQL Server Management Studio or with
Transact-SQL.
</p>
<p>
Before running the procedure, ensure that:
</p>
<ul>
<li>
You are a member of the
<code>
sysadmin
</code>
fixed server role for the SQL Server.
</li>
<li>
You are a
<code>
db_owner
</code>
of the database.
</li>
<li>
The SQL Server Agent is running.
</li>
</ul>
<p>
Then, follow the steps below to enable CDC:
</p>
<ol>
<li>
<p>
From the
<strong>
View
</strong>
menu in SQL Server Management Studio, click
<strong>
Template Explorer
</strong>
.
</p>
</li>
<li>
<p>
In the Template Browser, expand
<strong>
SQL Server Templates
</strong>
.
</p>
</li>
<li>
<p>
Expand
<strong>
Change Data Capture > Configuration
</strong>
and then click
<strong>
Enable Database for CDC
</strong>
.
</p>
</li>
<li>
<p>
In the template, replace the database name in the
<code>
USE
</code>
statement with the name of the
database where you want to enable CDC. For example, if your database was called
<code>
myDB
</code>
, the template would be:
</p>
<div class="highlight">
<pre class="chroma"><code class="language-sql" data-lang="sql"><span class="line"><span class="cl"><span class="n">USE</span><span class="w"> </span><span class="n">MyDB</span><span class="w">
</span></span></span><span class="line"><span class="cl"><span class="w"></span><span class="k">GO</span><span class="w">
</span></span></span><span class="line"><span class="cl"><span class="w"></span><span class="k">EXEC</span><span class="w"> </span><span class="n">sys</span><span class="p">.</span><span class="n">sp_cdc_enable_db</span><span class="w">
</span></span></span><span class="line"><span class="cl"><span class="w"></span><span class="k">GO</span><span class="w">
</span></span></span></code></pre>
</div>
</li>
<li>
<p>
Run the stored procedure
<code>
sys.sp_cdc_enable_db
</code>
to enable CDC for the database.
</p>
</li>
</ol>
<p>
When you enable CDC for the database, it creates a schema called
<code>
cdc
</code>
and also
a CDC user, metadata tables, and other system objects.
</p>
<p>
Keep the
<strong>
Change Data Capture > Configuration
</strong>
foldout open in the Template Explorer
because you will need it to enable CDC on the individual tables next.
</p>
<h2 id="2-enable-cdc-for-the-tables-you-want-to-capture">
2. Enable CDC for the tables you want to capture
</h2>
<p>
You must also enable CDC on the tables you want Debezium to capture using the
following steps (again, you need administrator privileges for this):
</p>
<ol>
<li>
<p>
With the
<strong>
Change Data Capture > Configuration
</strong>
foldout still open in the
Template Explorer, select
<strong>
Enable Table Specifying Filegroup Option
</strong>
.
</p>
</li>
<li>
<p>
In the template, replace the table name in the USE statement with the name of
the table you want to capture. For example, if your table was called
<code>
MyTable
</code>
then the template would look like the following:
</p>
<div class="highlight">

<li>
<p>
Run the stored procedure
<code>
sys.sp_cdc_enable_table
</code>
to enable CDC for
the table.
</p>
</li>
<li>
<p>
Repeat steps 1 to 3 for every table you want to capture.
</p>
</li>
</ol>
<h2 id="3-check-that-you-have-access-to-the-cdc-table">
3. Check that you have access to the CDC table
</h2>
<p>
You can use another stored procedure
<code>
sys.sp_cdc_help_change_data_capture
</code>
to query the CDC information for the database and check you have enabled
it correctly. Before doing this, check that:
</p>
<ul>
<li>
You have
<code>
SELECT
</code>
permission on all of the captured columns of the capture instance.
If you are a member of the
<code>
db_owner
</code>
database role then you can view information for
all of the defined capture instances.
</li>
<li>
You are a member of any gating roles that are defined for the table that the query includes.
</li>
</ul>
<p>
Follow the steps below to run
<code>
sys.sp_cdc_help_change_data_capture
</code>
:
</p>
<ol>
<li>
<p>
From the
<strong>
View
</strong>
menu in SQL Server Management Studio, click
<strong>
Object Explorer
</strong>
.
</p>
</li>
<li>
<p>
From the Object Explorer, expand
<strong>
Databases
</strong>
, and then expand your database
object, for example,

Run the
<code>
sys.sp_cdc_help_change_data_capture
</code>
stored procedure to query
the table. For example, if your database was called
<code>
MyDB
</code>
then you would
run the following:
</p>
<div class="highlight">
<pre class="chroma"><code class="language-sql" data-lang="sql"><span class="line"><span class="cl"><span class="n">USE</span><span class="w"> </span><span class="n">MyDB</span><span class="p">;</span><span class="w">

</div>
</li>
<li>
<p>
The query returns configuration information for each table in the database that
has CDC enabled and that contains change data that you are authorized to
access. If the result is empty then you should check that you have privileges
to access both the capture instance and the CDC tables.

You can also use the Debezium SQL Server connector with SQL Server on Azure.
See Microsoft's guide to

<h3 id="sql-server-capture-job-agent-configuration-parameters">
SQL Server capture job agent configuration parameters
</h3>
<p>
In SQL Server, the parameters that control the behavior of the capture job agent
are defined in the SQL Server table
<code>
msdb.dbo.cdc_jobs
</code>
. If you experience performance
problems while running the capture job agent then you can adjust the capture jobs
settings to reduce CPU load. To do this, run the
<code>
sys.sp_cdc_change_job
</code>
stored procedure
with your new parameter values.

<p>
The following parameters are the most important ones for modifying the capture agent behavior
of the Debezium SQL Server connector:
</p>
<ul>
<li>
<code>
pollinginterval
</code>
: This specifies the number of seconds that the capture agent
waits between log scan cycles. A higher value reduces the load on the database
host, but increases latency. A value of 0 specifies no wait between scans.
The default value is 5.
</li>
<li>
<code>
maxtrans
</code>
: This specifies the maximum number of transactions to process during
each log scan cycle. After the capture job processes the specified number of
transactions, it pauses for the length of time that
<code>
pollinginterval
</code>
specifies
before the next scan begins. A lower value reduces the load on the database host,
but increases latency. The default value is 500.
</li>
<li>
<code>
maxscans
</code>
: This specifies a limit on the number of scan cycles that the capture
job can attempt when capturing the full contents of the database transaction log.
If the continuous parameter is set to 1, the job pauses for the length of time
that the
<code>
pollinginterval
</code>
specifies before it resumes scanning. A lower values
reduces the load on the database host, but increases latency. The default value is 10.
</li>
</ul>
<p>
See the SQL Server documentation for more information about capture agent parameters.

<h2 id="handling-changes-to-the-schema">
Handling changes to the schema
</h2>
<p>
RDI can't adapt automatically when you change the schema of a CDC table in SQL Server. For example,
if you add a new column to a table you are capturing then RDI will generate errors
instead of capturing the changes correctly. See Debezium's
<a href="https://debezium.io/documentation/reference/stable/connectors/sqlserver.html#sqlserver-schema-evolution">
SQL Server schema evolution
</a>
docs for more information.
</p>
<p>
If you have administrator privileges, you can follow the steps below to update RDI after
a schema change and resume CDC. See the
<a href="https://debezium.io/documentation/reference/stable/connectors/sqlserver.html#online-schema-updates">
online schema updates
</a>
documentation for further details.
</p>
<ol>
<li>
<p>
Make your changes to the source table schema.
</p>
</li>
<li>
<p>
Create a new capture table for the updated source table by running the
<code>
sys.sp_cdc_enable_table
</code>
stored
procedure with a new, unique value for the parameter
<code>
@capture_instance
</code>
. For example, if the old value
was
<code>
dbo_customers
</code>
, you could replace it with
<code>
dbo_customers_v2
</code>
:

<h1>
Redis modules and blocking commands
</h1>
<p class="text-lg -mt-5 mb-10">
How to implement blocking commands in a Redis module
</p>
<p>
Redis has a few blocking commands among the built-in set of commands.
One of the most used is
<a href="/docs/latest/commands/blpop/">
<code>
BLPOP
</code>
</a>
(or the symmetric
<a href="/docs/latest/commands/brpop/">
<code>
BRPOP
</code>
</a>
) which blocks
waiting for elements arriving in a list.
</p>
<p>
The interesting fact about blocking commands is that they do not block
the whole server, but just the client calling them. Usually the reason to
block is that we expect some external event to happen: this can be
some change in the Redis data structures like in the
<a href="/docs/latest/commands/blpop/">
<code>
BLPOP
</code>
</a>
case, a
long computation happening in a thread, to receive some data from the
network, and so forth.
</p>
<p>
Redis modules have the ability to implement blocking commands as well,
this documentation shows how the API works and describes a few patterns
that can be used in order to model blocking commands.
</p>
<h2 id="how-blocking-and-resuming-works">
How blocking and resuming works.
</h2>
<p>
<em>
Note: You may want to check the
<code>
helloblock.c
</code>
example in the Redis source tree
inside the
<code>
src/modules
</code>
directory, for a simple to understand example
on how the blocking API is applied.
</em>
</p>
<p>
In Redis modules, commands are implemented by callback functions that
are invoked by the Redis core when the specific command is called
by the user. Normally the callback terminates its execution sending
some reply to the client. Using the following function instead, the
function implementing the module command may request that the client
is put into the blocked state:
</p>
<pre><code>RedisModuleBlockedClient *RedisModule_BlockClient(RedisModuleCtx *ctx, RedisModuleCmdFunc reply_callback, RedisModuleCmdFunc timeout_callback, void (*free_privdata)(void*), long long timeout_ms);
</code></pre>
<p>
The function returns a
<code>
RedisModuleBlockedClient
</code>
object, which is later
used in order to unblock the client. The arguments have the following
meaning:
</p>
<ul>
<li>
<code>
ctx
</code>
is the command execution context as usually in the rest of the API.
</li>
<li>
<code>
reply_callback
</code>
is the callback, having the same prototype of a normal command function, that is called when the client is unblocked in order to return a reply to the client.
</li>
<li>
<code>
timeout_callback
</code>
is the callback, having the same prototype of a normal command function that is called when the client reached the
<code>
ms
</code>
timeout.
</li>
<li>
<code>
free_privdata
</code>
is the callback that is called in order to free the private data. Private data is a pointer to some data that is passed between the API used to unblock the client, to the callback that will send the reply to the client. We'll see how this mechanism works later in this document.
</li>
<li>
<code>
ms
</code>
is the timeout in milliseconds. When the timeout is reached, the timeout callback is called and the client is automatically aborted.
</li>
</ul>
<p>
Once a client is blocked, it can be unblocked with the following API:
</p>
<pre><code>int RedisModule_UnblockClient(RedisModuleBlockedClient *bc, void *privdata);
</code></pre>
<p>
The function takes as argument the blocked client object returned by
the previous call to
<code>
RedisModule_BlockClient()
</code>
, and unblock the client.
Immediately before the client gets unblocked, the
<code>
reply_callback
</code>
function
specified when the client was blocked is called: this function will
have access to the
<code>
privdata
</code>
pointer used here.
</p>
<p>
IMPORTANT: The above function is thread safe, and can be called from within
a thread doing some work in order to implement the command that blocked
the client.
</p>
<p>
The
<code>
privdata
</code>
data will be freed automatically using the
<code>
free_privdata
</code>
callback when the client is unblocked. This is useful
<strong>
since the reply
callback may never be called
</strong>
in case the client timeouts or disconnects
from the server, so it's important that it's up to an external function
to have the responsibility to free the data passed if needed.
</p>
<p>
To better understand how the API works, we can imagine writing a command
that blocks a client for one second, and then send as reply "Hello!".
</p>
<p>
Note: arity checks and other non important things are not implemented
int his command, in order to take the example simple.
</p>
<pre><code>int Example_RedisCommand(RedisModuleCtx *ctx, RedisModuleString **argv,
int argc)
{
RedisModuleBlockedClient *bc =
RedisModule_BlockClient(ctx,reply_func,timeout_func,NULL,0);
pthread_t tid;
pthread_create(&tid,NULL,threadmain,bc);
return REDISMODULE_OK;
}
void *threadmain(void *arg) {
RedisModuleBlockedClient *bc = arg;
sleep(1); /* Wait one second and unblock. */
RedisModule_UnblockClient(bc,NULL);
}
</code></pre>
<p>
The above command blocks the client ASAP, spawning a thread that will
wait a second and will unblock the client. Let's check the reply and
timeout callbacks, which are in our case very similar, since they
just reply the client with a different reply type.
</p>
<pre><code>int reply_func(RedisModuleCtx *ctx, RedisModuleString **argv,
int argc)
{
return RedisModule_ReplyWithSimpleString(ctx,"Hello!");
}
int timeout_func(RedisModuleCtx *ctx, RedisModuleString **argv,
int argc)
{
return RedisModule_ReplyWithNull(ctx);
}
</code></pre>
<p>
The reply callback just sends the "Hello!" string to the client.
The important bit here is that the reply callback is called when the
client is unblocked from the thread.
</p>
<p>
The timeout command returns
<code>
NULL
</code>
, as it often happens with actual
Redis blocking commands timing out.
</p>
<h2 id="passing-reply-data-when-unblocking">
Passing reply data when unblocking
</h2>
<p>
The above example is simple to understand but lacks an important
real world aspect of an actual blocking command implementation: often
the reply function will need to know what to reply to the client,
and this information is often provided as the client is unblocked.
</p>
<p>
We could modify the above example so that the thread generates a
random number after waiting one second. You can think at it as an
actually expansive operation of some kind. Then this random number
can be passed to the reply function so that we return it to the command
caller. In order to make this working, we modify the functions as follow:
</p>
<pre><code>void *threadmain(void *arg) {
RedisModuleBlockedClient *bc = arg;
sleep(1); /* Wait one second and unblock. */
long *mynumber = RedisModule_Alloc(sizeof(long));
*mynumber = rand();
RedisModule_UnblockClient(bc,mynumber);
}
</code></pre>
<p>
As you can see, now the unblocking call is passing some private data,
that is the
<code>
mynumber
</code>
pointer, to the reply callback. In order to
obtain this private data, the reply callback will use the following
function:
</p>
<pre><code>void *RedisModule_GetBlockedClientPrivateData(RedisModuleCtx *ctx);
</code></pre>
<p>
So our reply callback is modified like that:
</p>
<pre><code>int reply_func(RedisModuleCtx *ctx, RedisModuleString **argv,
int argc)
{
long *mynumber = RedisModule_GetBlockedClientPrivateData(ctx);
/* IMPORTANT: don't free mynumber here, but in the
* free privdata callback. */
return RedisModule_ReplyWithLongLong(ctx,mynumber);
}
</code></pre>
<p>
Note that we also need to pass a
<code>
free_privdata
</code>
function when blocking
the client with
<code>
RedisModule_BlockClient()
</code>
, since the allocated
long value must be freed. Our callback will look like the following:
</p>
<pre><code>void free_privdata(void *privdata) {
RedisModule_Free(privdata);
}
</code></pre>
<p>
NOTE: It is important to stress that the private data is best freed in the
<code>
free_privdata
</code>
callback because the reply function may not be called
if the client disconnects or timeout.
</p>
<p>
Also note that the private data is also accessible from the timeout
callback, always using the
<code>
GetBlockedClientPrivateData()
</code>
API.
</p>
<h2 id="aborting-the-blocking-of-a-client">
Aborting the blocking of a client
</h2>
<p>
One problem that sometimes arises is that we need to allocate resources
in order to implement the non blocking command. So we block the client,
then, for example, try to create a thread, but the thread creation function
returns an error. What to do in such a condition in order to recover? We
don't want to take the client blocked, nor we want to call
<code>
UnblockClient()
</code>
because this will trigger the reply callback to be called.
</p>
<p>
In this case the best thing to do is to use the following function:
</p>
<pre><code>int RedisModule_AbortBlock(RedisModuleBlockedClient *bc);
</code></pre>
<p>
Practically this is how to use it:
</p>
<pre><code>int Example_RedisCommand(RedisModuleCtx *ctx, RedisModuleString **argv,
int argc)
{
RedisModuleBlockedClient *bc =
RedisModule_BlockClient(ctx,reply_func,timeout_func,NULL,0);
pthread_t tid;
if (pthread_create(&tid,NULL,threadmain,bc) != 0) {
RedisModule_AbortBlock(bc);
RedisModule_ReplyWithError(ctx,"Sorry can't create a thread");
}
return REDISMODULE_OK;
}
</code></pre>
<p>
The client will be unblocked but the reply callback will not be called.
</p>
<h2 id="implementing-the-command-reply-and-timeout-callback-using-a-single-function">
Implementing the command, reply and timeout callback using a single function
</h2>
<p>
The following functions can be used in order to implement the reply and
callback with the same function that implements the primary command
function:
</p>
<pre><code>int RedisModule_IsBlockedReplyRequest(RedisModuleCtx *ctx);
int RedisModule_IsBlockedTimeoutRequest(RedisModuleCtx *ctx);
</code></pre>
<p>
So I could rewrite the example command without using a separated
reply and timeout callback:
</p>
<pre><code>int Example_RedisCommand(RedisModuleCtx *ctx, RedisModuleString **argv,
int argc)
{
if (RedisModule_IsBlockedReplyRequest(ctx)) {
long *mynumber = RedisModule_GetBlockedClientPrivateData(ctx);
return RedisModule_ReplyWithLongLong(ctx,mynumber);
} else if (RedisModule_IsBlockedTimeoutRequest) {
return RedisModule_ReplyWithNull(ctx);
}
RedisModuleBlockedClient *bc =
RedisModule_BlockClient(ctx,reply_func,timeout_func,NULL,0);
pthread_t tid;
if (pthread_create(&tid,NULL,threadmain,bc) != 0) {
RedisModule_AbortBlock(bc);
RedisModule_ReplyWithError(ctx,"Sorry can't create a thread");
}
return REDISMODULE_OK;
}
</code></pre>
<p>
Functionally is the same but there are people that will prefer the less
verbose implementation that concentrates most of the command logic in a
single function.
</p>
<h2 id="working-on-copies-of-data-inside-a-thread">
Working on copies of data inside a thread
</h2>
<p>
An interesting pattern in order to work with threads implementing the
slow part of a command, is to work with a copy of the data, so that
while some operation is performed in a key, the user continues to see
the old version. However when the thread terminated its work, the
representations are swapped and the new, processed version, is used.
</p>
<p>
An example of this approach is the
<a href="https://github.com/antirez/neural-redis">
Neural Redis module
</a>
where neural networks are trained in different threads while the
user can still execute and inspect their older versions.
</p>
<h2 id="future-work">
Future work
</h2>
<p>
An API is work in progress right now in order to allow Redis modules APIs
to be called in a safe way from threads, so that the threaded command
can access the data space and do incremental operations.
</p>
<p>
There is no ETA for this feature but it may appear in the course of the
Redis 4.0 release at some point.

<h1>
Debugging
</h1>
<p class="text-lg -mt-5 mb-10">
A guide to debugging Redis server processes
</p>
<p>
Redis is developed with an emphasis on stability. We do our best with
every release to make sure you'll experience a stable product with no
crashes. However, if you ever need to debug the Redis process itself, read on.
</p>
<p>
When Redis crashes, it produces a detailed report of what happened. However,
sometimes looking at the crash report is not enough, nor is it possible for
the Redis core team to reproduce the issue independently. In this scenario, we
need help from the user who can reproduce the issue.
</p>
<p>
This guide shows how to use GDB to provide the information the
Redis developers will need to track the bug more easily.
</p>
<h2 id="what-is-gdb">
What is GDB?
</h2>
<p>
GDB is the Gnu Debugger: a program that is able to inspect the internal state
of another program. Usually tracking and fixing a bug is an exercise in
gathering more information about the state of the program at the moment the
bug happens, so GDB is an extremely useful tool.
</p>
<p>
GDB can be used in two ways:
</p>
<ul>
<li>
It can attach to a running program and inspect the state of it at runtime.
</li>
<li>
It can inspect the state of a program that already terminated using what is called a
<em>
core file
</em>
, that is, the image of the memory at the time the program was running.
</li>
</ul>
<p>
From the point of view of investigating Redis bugs we need to use both of these
GDB modes. The user able to reproduce the bug attaches GDB to their running Redis
instance, and when the crash happens, they create the
<code>
core
</code>
file that in turn
the developer will use to inspect the Redis internals at the time of the crash.
</p>
<p>
This way the developer can perform all the inspections in his or her computer
without the help of the user, and the user is free to restart Redis in their
production environment.
</p>
<h2 id="compiling-redis-without-optimizations">
Compiling Redis without optimizations
</h2>
<p>
By default Redis is compiled with the
<code>
-O2
</code>
switch, this means that compiler
optimizations are enabled. This makes the Redis executable faster, but at the
same time it makes Redis (like any other program) harder to inspect using GDB.
</p>
<p>
It is better to attach GDB to Redis compiled without optimizations using the
<code>
make noopt
</code>
command (instead of just using the plain
<code>
make
</code>
command). However,
if you have an already running Redis in production there is no need to recompile
and restart it if this is going to create problems on your side. GDB still works
against executables compiled with optimizations.
</p>
<p>
You should not be overly concerned at the loss of performance from compiling Redis
without optimizations. It is unlikely that this will cause problems in your
environment as Redis is not very CPU-bound.
</p>
<h2 id="attaching-gdb-to-a-running-process">
Attaching GDB to a running process
</h2>
<p>
If you have an already running Redis server, you can attach GDB to it, so that
if Redis crashes it will be possible to both inspect the internals and generate
a
<code>
core dump
</code>
file.
</p>
<p>
After you attach GDB to the Redis process it will continue running as usual without
any loss of performance, so this is not a dangerous procedure.
</p>
<p>
In order to attach GDB the first thing you need is the
<em>
process ID
</em>
of the running
Redis instance (the
<em>
pid
</em>
of the process). You can easily obtain it using
<code>
redis-cli
</code>
:
</p>
<pre><code>$ redis-cli info | grep process_id
process_id:58414
</code></pre>
<p>
In the above example the process ID is
<strong>
58414
</strong>
.
</p>
<p>
Login into your Redis server.
</p>
<p>
(Optional but recommended) Start
<strong>
screen
</strong>
or
<strong>
tmux
</strong>
or any other program that will make sure that your GDB session will not be closed if your ssh connection times out. You can learn more about screen in
<a href="http://www.linuxjournal.com/article/6340">
this article
</a>
.
</p>
<p>
Attach GDB to the running Redis server by typing:
</p>
<pre><code>$ gdb <path-to-redis-executable> <pid>
</code></pre>
<p>
For example:
</p>
<pre><code>$ gdb /usr/local/bin/redis-server 58414
</code></pre>
<p>
GDB will start and will attach to the running server printing something like the following:
</p>
<pre><code>Reading symbols for shared libraries + done
0x00007fff8d4797e6 in epoll_wait ()
(gdb)
</code></pre>
<p>
At this point GDB is attached but
<strong>
your Redis instance is blocked by GDB
</strong>
. In
order to let the Redis instance continue the execution just type
<strong>
continue
</strong>
at
the GDB prompt, and press enter.
</p>
<pre><code>(gdb) continue
Continuing.
</code></pre>
<p>
Done! Now your Redis instance has GDB attached. Now you can wait for the next crash. :)
</p>
<p>
Now it's time to detach your screen/tmux session, if you are running GDB using it, by
pressing
<strong>
Ctrl-a a
</strong>
key combination.
</p>
<h2 id="after-the-crash">
After the crash
</h2>
<p>
Redis has a command to simulate a segmentation fault (in other words a bad crash) using
the
<code>
DEBUG SEGFAULT
</code>
command (don't use it against a real production instance of course!
So I'll use this command to crash my instance to show what happens in the GDB side:
</p>
<pre><code>(gdb) continue
Continuing.
Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_INVALID_ADDRESS at address: 0xffffffffffffffff
debugCommand (c=0x7ffc32005000) at debug.c:220
220 *((char*)-1) = 'x';
</code></pre>
<p>
As you can see GDB detected that Redis crashed, and was even able to show me
the file name and line number causing the crash. This is already much better
than the Redis crash report back trace (containing just function names and
binary offsets).
</p>
<h2 id="obtaining-the-stack-trace">
Obtaining the stack trace
</h2>
<p>
The first thing to do is to obtain a full stack trace with GDB. This is as
simple as using the
<strong>
bt
</strong>
command:
</p>
<pre><code>(gdb) bt
#0 debugCommand (c=0x7ffc32005000) at debug.c:220
#1 0x000000010d246d63 in call (c=0x7ffc32005000) at redis.c:1163
#2 0x000000010d247290 in processCommand (c=0x7ffc32005000) at redis.c:1305
#3 0x000000010d251660 in processInputBuffer (c=0x7ffc32005000) at networking.c:959
#4 0x000000010d251872 in readQueryFromClient (el=0x0, fd=5, privdata=0x7fff76f1c0b0, mask=220924512) at networking.c:1021
#5 0x000000010d243523 in aeProcessEvents (eventLoop=0x7fff6ce408d0, flags=220829559) at ae.c:352
#6 0x000000010d24373b in aeMain (eventLoop=0x10d429ef0) at ae.c:397
#7 0x000000010d2494ff in main (argc=1, argv=0x10d2b2900) at redis.c:2046
</code></pre>
<p>
This shows the backtrace, but we also want to dump the processor registers using the
<strong>
info registers
</strong>
command:
</p>
<pre><code>(gdb) info registers
rax 0x0 0
rbx 0x7ffc32005000 140721147367424

</code></pre>
<p>
Please
<strong>
make sure to include
</strong>
both of these outputs in your bug report.
</p>
<h2 id="obtaining-the-core-file">
Obtaining the core file
</h2>
<p>
The next step is to generate the core dump, that is the image of the memory of the running Redis process. This is done using the
<code>
gcore
</code>
command:
</p>
<pre><code>(gdb) gcore
Saved corefile core.58414
</code></pre>
<p>
Now you have the core dump to send to the Redis developer, but
<strong>
it is important
to understand
</strong>
that this happens to contain all the data that was inside the
Redis instance at the time of the crash; Redis developers will make sure not to
share the content with anyone else, and will delete the file as soon as it is no
longer used for debugging purposes, but you are warned that by sending the core
file you are sending your data.
</p>
<h2 id="what-to-send-to-developers">
What to send to developers
</h2>
<p>
Finally you can send everything to the Redis core team:
</p>
<ul>
<li>
The Redis executable you are using.
</li>
<li>
The stack trace produced by the
<strong>
bt
</strong>
command, and the registers dump.
</li>
<li>
The core file you generated with gdb.
</li>
<li>
Information about the operating system and GCC version, and Redis version you are using.
</li>
</ul>
<h2 id="thank-you">
Thank you
</h2>
<p>
Your help is extremely important! Many issues can only be tracked this way. So
thanks!

<code>
BLMOVE
</code>
is the blocking variant of
<a href="/docs/latest/commands/lmove/">
<code>
LMOVE
</code>
</a>
.
When
<code>
source
</code>
contains elements, this command behaves exactly like
<a href="/docs/latest/commands/lmove/">
<code>
LMOVE
</code>
</a>
.
When used inside a
<a href="/docs/latest/commands/multi/">
<code>
MULTI
</code>
</a>
/
<a href="/docs/latest/commands/exec/">
<code>
EXEC
</code>
</a>
block, this command behaves exactly like
<a href="/docs/latest/commands/lmove/">
<code>
LMOVE
</code>
</a>
.
When
<code>
source
</code>
is empty, Redis will block the connection until another client
pushes to it or until
<code>
timeout
</code>
(a double value specifying the maximum number of seconds to block) is reached.
A
<code>
timeout
</code>
of zero can be used to block indefinitely.
</p>
<p>
This command comes in place of the now deprecated
<a href="/docs/latest/commands/brpoplpush/">
<code>
BRPOPLPUSH
</code>
</a>
. Doing
<code>
BLMOVE RIGHT LEFT
</code>
is equivalent.

<h1>
Use persistent volumes in Redis Enterprise clusters
</h1>
<p class="text-lg -mt-5 mb-10">
This section covers details about how persistent volumes are sized and specified for Redis Enterprise cluster deployments.
</p>
<h2 id="storage-types">
Storage types
</h2>
<p>
Redis Enterprise for Kubernetes can only use storage classes supported by block storage. Block storage is mounted at the Kubernetes node level and utilizes EXT4 or XFS file systems. It can be sourced from enterprise-grade SANs or cloud environments such as EBS, Azure Managed Disks, or GCP persistent disks.

<div class="font-medium">
Warning:
</div>
NFS, NFS-like, and multi-read-write/shared storage options are not supported. These types of storage are often slow and can cause locking behaviors that are incompatible with the requirements of database storage.
</div>
</div>
<h2 id="rec-persistentspec-field">
REC

field
</h2>
<p>
To deploy a Redis Enterprise cluster with Redis Enterprise operator the
spec should include a
<em>
persistentSpec
</em>
section, in the
<em>
redis-enterprise-cluster.yaml
</em>
file:
</p>
<pre><code>spec:
nodes: 3
persistentSpec:
enabled: true
storageClassName: "standard"
volumeSize: "23Gi” #optional
</code></pre>
<p>
Persistence storage is a requirement for production deployments.

Note:

For
<strong>
production deployments
</strong>
of Redis Enterprise Cluster on Kubernetes,
the Redis Enterprise Cluster (REC) must be deployed with persistence enabled.
The REC deployment files in the
<a href="https://github.com/RedisLabs/redis-enterprise-k8s-docs">
Kubernetes documentation
</a>
contain this declaration by default.
</div>
</div>
<h2 id="volume-size">
Volume size
</h2>
<p>
<em>
volumeSize
</em>
is an optional definition. By default, if the definition is
omitted, operator allocates five times (5x) the amount of memory (RAM)
defined for nodes (see example below), which is the recommended
persistent storage size as described in the
<a href="/docs/latest/operate/rs/installing-upgrading/install/plan-deployment/hardware-requirements/">
Hardware
requirements
</a>
article.
</p>
<p>
To explicitly specify the persistent storage size, use the
<em>
volumeSize
</em>
property as described in the example above.
</p>
<p>
Persistent volume claims can be expanded, but not reduced after creation. See
<a href="/docs/latest/operate/kubernetes/re-clusters/expand-pvc/">
Expand PersistentVolumeClaim (PVC)
</a>
for details.

<h2 id="storage-class-name">
Storage class name
</h2>
<p>
<em>
storageClassName
</em>
determines the Storage Class resource, which is
defined by the Kubernetes cluster administrator, to be used for
persistent storage.
</p>
<p>
Different Kubernetes distributions and different deployments use
different Storage Class resources.
</p>
<p>
In order to determine the Storage Class resources available for your K8s
deployment, use the following command:
</p>
<pre><code>kubectl get StorageClass
</code></pre>
<p>
Typically, AWS provides “gp2” as the Storage Class name while GKE uses “standard.”
Azure provides two Storage Classes: "default" using HDDs, and "managed-premium" using SSDs.
</p>
<p>
Below is an example of a response to the command.

<ul>
<li>
Only new samples that are added into the source series after the creation of the rule will be aggregated.
</li>
<li>
Calling
<code>
TS.CREATERULE
</code>
with a nonempty
<code>
destKey
</code>
may result in inconsistencies between the raw and the compacted data.
</li>
<li>
Explicitly adding samples to a compacted time series (using

</a>
) may result in inconsistencies between the raw and the compacted data. The compaction process may override such samples.
</li>
<li>
If no samples are added to the source time series during a bucket period. no
<em>
compacted sample
</em>
is added to the destination time series.
</li>
<li>
The timestamp of a compacted sample added to the destination time series is set to the start timestamp the appropriate compaction bucket. For example, for a 10-minute compaction bucket with no alignment, the compacted samples timestamps are
<code>
x:00

,
<code>
x:10

<h2 id="additional-capabilities">
Additional capabilities
</h2>
<ul>
<li>
<p>
Added the ability to retrieve license details with a REST API command.
Now you can get your license details from the admin console (settings > general) or from the REST API command:
</p>
<p>
<code>
GET https://localhost:9443/v1/license
</code>
</p>
<p>
The REST API response includes:
</p>
<ul>
<li>
license - The cluster’s name (FQDN) in the key string
</li>
<li>
expired - If the cluster key is expired (True or False)
</li>
<li>
activation_date - The date of the cluster key activation
</li>
<li>
expiration_date - The date of the cluster key expiration
</li>
<li>
shards_limit - The number of shards allowed by the cluster key
</li>
</ul>
</li>
<li>
<p>
Added Flush command in the UI console for Active-Active databases. The command flushes the data from all participating clusters.
</p>
</li>
<li>
<p>
Updated
<code>
rladmin upgrade module
</code>
command so module arguments are optional. When you upgrade the module for a database, you can either:
</p>
<ul>
<li>
Specify the module arguments to replace the existing arguments
</li>
<li>
Specify the
<code>
keep_module_args
</code>
flag to use the existing arguments
</li>
</ul>
<p>
Examples:
</p>
<ol>
<li>
<p>
To upgrade the version of RediSearch to 10017 and replace the module arguments:
</p>
<p>
<code>
rladmin upgrade module db_name MyAwesomeDB module_name ft version 10017 module_args "PARTITIONS AUTO"
</code>
</p>
</li>
<li>
<p>
To upgrade RedisBloom to version 10100 and remove the current module arguments:
</p>
<p>
<code>
rladmin upgrade module db_name MyDB module_name bf version 10100 module_args " "
</code>
</p>
</li>
<li>
<p>
To upgrade RedisJSON to 10002 and use the current module arguments:
</p>
<p>
<code>
rladmin upgrade module db_name MyDB module_name ReJSON version 10002 keep_module_args
</code>
</p>
</li>
</ol>
</li>
<li>
<p>
Upgraded
<code>
js-yaml
</code>
version to 3.13.1, and
<code>
lodash
</code>
version to 4.17.15 (RS31819)
</p>
</li>
<li>
<p>
Added an alert for actions that run for an extended period of time. For example, a notification is sent when an action like updating database property runs for more than a configurable threshold. Default value is set to 24 hours.
</p>
</li>
</ul>
<h2 id="information">
Information
</h2>
<ul>
<li>
End of Life (EOL) for Redis Enterprise Software 5.4, as well as for Redis Modules and previous RS versions, can be found
<a href="https://docs.redis.com/latest/rs/installing-upgrading/product-lifecycle">
here
</a>
.
</li>
<li>
Google Chrome browser on macOS Catalina requires self-signed certificate generated after June 2019 to include the extendedKeyUsage field in order to connect to the RS admin console.
If you use a self-signed certificate that does not include this field,
<a href="/docs/latest/operate/rs/security/certificates/updating-certificates/">
update the self-signed certificate
</a>
.
</li>
<li>
When you upgrade an Active-Active Redis with active AOF from version RS 5.4.2 or lower to version RS 5.4.4 or higher:
<ul>
<li>
If replication is enabled, you must run the BGREWRITEAOF command on all replica shards after the upgrade.
</li>
<li>
If replication is not enabled, you must run the BGREWRITEAOF command on all shards after the upgrade.
</li>
</ul>
</li>
</ul>
<h2 id="important-fixes">
Important fixes
</h2>
<ul>
<li>
RS23396 - Improved the disconnection mechanism in case of inactive UI session
</li>
<li>
RS27924 - Added descriptive error messages in the UI console when validating the license
</li>
<li>
RS29968 - Improved internal mechanism to better support high scale of clients connections
</li>
<li>
RS35675 - Updated the upgrade process of Active-Active Redis databases to save causal consistency and encryption flags
</li>
<li>
RS36922 - Fixed an issue in a specific cluster upgrade scenario from versions earlier than RS 5.4.0 to RS 5.4.0 or higher
</li>
</ul>
<h2 id="known-limitations">
Known limitations
</h2>
<h3 id="upgrade">
Upgrade
</h3>
<ul>
<li>
When you upgrade a cluster from version 5.0.2-20 to version 5.4.14, you must first upgrade to version 5.2.2 and then to version 5.4.14.
</li>
<li>
<a href="/docs/latest/operate/rs/release-notes/legacy-release-notes/rs-5-4-2-april-2019/">
RS 5.4.2
</a>
introduced new Active-Active Redis (CRDB) capabilities
that improve its compatibility with open source Redis.
Now the string data-type in Active-Active Redis (CRDB) is implicitly and dynamically typed, just like open source Redis.
To use the new capabilities on nodes that are upgraded from version RS 5.4.2 or lower,
you must
<a href="/docs/latest/operate/rs/installing-upgrading/upgrading/#upgrading-crdbs">
upgrade the CRDB protocol
</a>
.
</li>
<li>
Before you upgrade a database with RediSearch Module to Redis 5.0,
you must
<a href="/docs/latest/operate/oss_and_stack/stack-with-enterprise/install/upgrade-module/">
upgrade the RediSearch Module
</a>
to version 1.4.2 or above.
</li>
<li>
Node upgrade fails if the SSL certificates were configured in version 5.0.2 or above
by manually updating the certificates on the disk instead of
<a href="/docs/latest/operate/rs/security/certificates/updating-certificates/">
updating them through the API
</a>
.
For assistance with this issue,
<a href="https://redislabs.com/company/support/">
contact Redis support
</a>
.
</li>
<li>
We recommend that you test module upgrade commands in a test environment before you upgrade modules in a production environment.
The module upgrade arguments are not validated during the upgrade process and incorrect arguments can cause unexpected downtime.
</li>
<li>
Starting from RS 5.4.2, to preserve the current Redis major.minor version during database upgrade you must use the
<code>
keep_redis_version
</code>
option instead of
<code>
keep_current_version
</code>
.
</li>
</ul>
<h3 id="cluster-api">
Cluster API
</h3>
<ul>
<li>
<p>
The API for removing a node is updated in RS 5.4.2 or higher. The API call must include json data and the "Content-Type: application/json" header. For example:
</p>
<p>
<code>
curl -X POST -H "Content-Type: application/json" -i -k -u [email protected]:password https://localhost:9443/v1/nodes/3/actions/remove --data "{}"
</code>
</p>
</li>
</ul>
<h3 id="discovery-service">
Discovery service
</h3>
<ul>
<li>
For
<a href="/docs/latest/operate/rs/databases/durability-ha/discovery-service/">
Redis Sentinel (Discovery Service)
</a>
, every database name must be unique across the cluster.
</li>
</ul>
<h3 id="redis-commands">
Redis commands
</h3>
<ul>
<li>
The capability of disabling specific Redis commands does not work on commands specific to Redis Modules.
</li>
<li>
The CLIENT ID command cannot guarantee incremental IDs between clients that connect to different nodes under multi proxy policies.
</li>
<li>
CLIENT UNBLOCK command is not supported in RS 5.4 and above
</li>
<li>
Starting from RS 5.4.2 and after upgrading the CRDB, TYPE command for string data-type in CRDBs return "string" (OSS Redis standard).
</li>

<h1>
Manage Active-Active databases
</h1>
<p class="text-lg -mt-5 mb-10">
Manage your Active-Active database settings.
</p>
<p>
You can configure and manage your Active-Active database from either the Cluster Manager UI or the command line.
</p>
<p>
To change the global configuration of the Active-Active database, use
<a href="/docs/latest/operate/rs/7.4/references/cli-utilities/crdb-cli/">
<code>
crdb-cli
</code>
</a>
.
</p>
<p>
If you need to apply changes locally to one database instance, you use the Cluster Manager UI or
<a href="/docs/latest/operate/rs/7.4/references/cli-utilities/rladmin/">
<code>
rladmin
</code>
</a>
.
</p>
<h2 id="database-settings">
Database settings
</h2>
<p>
Many Active-Active database settings can be changed after database creation. One notable exception is database clustering. Database clustering can't be turned on or off after the database has been created.
</p>
<h2 id="participating-clusters">
Participating clusters
</h2>
<p>
You can add and remove participating clusters of an Active-Active database to change the topology.
To manage the changes to Active-Active topology, use
<a href="/docs/latest/operate/rs/7.4/references/cli-utilities/crdb-cli/">
<code>
crdb-cli
</code>
</a>
or the participating clusters list in the Cluster Manager UI.
</p>
<h3 id="add-participating-clusters">
Add participating clusters
</h3>
<p>
All existing participating clusters must be online and in a syncing state when you add new participating clusters.
</p>
<p>
New participating clusters create the Active-Active database instance based on the global Active-Active database configuration.
After you add new participating clusters to an existing Active-Active database,
the new database instance can accept connections and read operations.
The new instance does not accept write operations until it is in the syncing state.

<p>
To add a new participating cluster to an existing Active-Active configuration using the Cluster Manager UI:

</strong>
.
</p>
</li>
<li>
<p>
In the
<strong>
Participating clusters

section, go to
<strong>
Other participating clusters
</strong>
and click
<strong>

<h3 id="remove-participating-clusters">
Remove participating clusters
</h3>
<p>
All existing participating clusters must be online and in a syncing state when you remove an online participating cluster.
If you must remove offline participating clusters, you can forcefully remove them.
If a forcefully removed participating cluster tries to rejoin the cluster,
its Active-Active database membership will be out of date.
The joined participating clusters reject updates sent from the removed participating cluster.
To prevent rejoin attempts, purge the forcefully removed instance from the participating cluster.
</p>
<p>
To remove a participating cluster using the Cluster Manager UI:
</p>
<ol>
<li>
<p>
Select the Active-Active database from the
<strong>

<li>
<p>
Click
<strong>

Replication backlog
</h2>
<p>
Redis databases that use
<a href="/docs/latest/operate/rs/7.4/databases/durability-ha/replication/">
replication for high availability
</a>
maintain a replication backlog (per shard) to synchronize the primary and replica shards of a database. In addition to the database replication backlog, Active-Active databases maintain a backlog (per shard) to synchronize the database instances between clusters.
</p>
<p>
By default, both the database and Active-Active replication backlogs are set to one percent (1%) of the database size divided by the number of shards. This can range between 1MB to 250MB per shard for each backlog.
</p>
<h3 id="change-the-replication-backlog-size">
Change the replication backlog size
</h3>
<p>
Use the
<a href="/docs/latest/operate/rs/7.4/references/cli-utilities/crdb-cli/">
<code>
crdb-cli
</code>
</a>
utility to control the size of the replication backlogs. You can set it to
<code>
auto
</code>
or set a specific size.
</p>
<p>
Update the database replication backlog configuration with the
<code>
crdb-cli
</code>
command shown below.
</p>
<div class="highlight">

<p>
Active-Active supports AOF (Append-Only File) data persistence only. Snapshot persistence is

If an Active-Active database is currently using snapshot data persistence, use

Set the
<strong>
last delivered ID
</strong>
for a consumer group.
</p>
<p>
Normally, a consumer group's last delivered ID is set when the group is created with
<a href="/docs/latest/commands/xgroup-create/">
<code>
XGROUP CREATE
</code>
</a>
.
The
<code>
XGROUP SETID
</code>
command allows modifying the group's last delivered ID, without having to delete and recreate the group.
For instance if you want the consumers in a consumer group to re-process all the messages in a stream, you may want to set its next ID to 0:
</p>
<pre><code>XGROUP SETID mystream mygroup 0
</code></pre>
<p>
The optional
<code>
entries_read
</code>
argument can be specified to enable consumer group lag tracking for an arbitrary ID.
An arbitrary ID is any ID that isn't the ID of the stream's first entry, its last entry or the zero ("0-0") ID.
This can be useful you know exactly how many entries are between the arbitrary ID (excluding it) and the stream's last entry.
In such cases, the
<code>
entries_read
</code>
can be set to the stream's
<code>
entries_added
</code>
subtracted with the number of entries.

<ul>
<li>
<p>
When specified key does not exist, a new time series is created.
</p>
<p>
if a
<a href="/docs/latest/develop/data-types/timeseries/configuration#compaction_policy">
COMPACTION_POLICY
</a>
configuration parameter is defined, compacted time series would be created as well.
</p>
</li>
<li>
<p>
If
<code>
timestamp
</code>
is older than the retention period compared to the maximum existing timestamp, the sample is discarded and an error is returned.
</p>
</li>
<li>
<p>
When adding a sample to a time series for which compaction rules are defined:
</p>
<ul>
<li>
If all the original samples for an affected aggregated time bucket are available, the compacted value is recalculated based on the reported sample and the original samples.
</li>
<li>
If only a part of the original samples for an affected aggregated time bucket is available due to trimming caused in accordance with the time series RETENTION policy, the compacted value is recalculated based on the reported sample and the available original samples.
</li>
<li>
If the original samples for an affected aggregated time bucket are not available due to trimming caused in accordance with the time series RETENTION policy, the compacted value bucket is not updated.
</li>
</ul>
</li>
<li>
<p>
Explicitly adding samples to a compacted time series (using

<h3 id="upload-cluster-license-key">
Upload cluster license key
</h3>
<p>
After purchasing a cluster license and if your account has the "Admin" role,
you can upload the cluster license key, either during initial
cluster creation or at any time afterward. The license key defines various
cluster settings, such as the maximum number of shards you can have in
the cluster. For more detailed information see
<a href="/docs/latest/operate/rs/clusters/configure/license-keys/">
Cluster license
keys
</a>
.
</p>
<h3 id="view-max-number-of-allowed-shards">
View max number of allowed shards
</h3>
<p>
The maximum number of allowed shards, which is determined by the cluster license
key, appears in the
<strong>
Max number of shards
</strong>
field in the
<strong>
License
</strong>
section.
</p>
<h3 id="view-cluster-name">
View cluster name
</h3>
<p>
The cluster name appears in the
<strong>
Cluster name
</strong>
field in the
<strong>
License
</strong>
section. This gives a
common name that your team or Redis support can refer to. It is
especially helpful if you have multiple clusters.
</p>
<h3 id="set-time-zone">
Set time zone
</h3>
<p>
You can change the
<strong>
Time zone
</strong>
field to ensure the date, time fields, and log entries in the Cluster Manager UI are shown in your preferred time zone. This setting doesn't affect other system logs or services.
</p>
<h2 id="alert-settings-tab">

<p>
The
<strong>
Alert Settings
</strong>
tab lets you configure alerts that are relevant to the entire cluster, such as alerts for cluster utilization, nodes, node utilization, security, and database utilization.
</p>
<p>
You can also configure email server settings and

<h2 id="known-limitations">
Known limitations
</h2>
<h3 id="large-clusters">
Large clusters
</h3>
<p>
On clusters with more than 9 REC nodes, a Kubernetes upgrade can render the Redis cluster unresponsive in some cases. A fix is available in the 6.4.2-5 release. Upgrade your operator version to 6.4.2-5 or later before upgrading your Kubernetes cluster. (RED-93025)
</p>
<h3 id="long-cluster-names-cause-routes-to-be-rejected--red-25871">
Long cluster names cause routes to be rejected (RED-25871)
</h3>
<p>
A cluster name longer than 20 characters will result in a rejected route configuration because the host part of the domain name will exceed 63 characters. The workaround is to limit cluster name to 20 characters or less.
</p>
<h3 id="cluster-cr-rec-errors-are-not-reported-after-invalid-updates-red-25542">
Cluster CR (REC) errors are not reported after invalid updates (RED-25542)
</h3>
<p>
A cluster CR specification error is not reported if two or more invalid CR resources are updated in sequence.
</p>
<h3 id="an-unreachable-cluster-has-status-running-red-32805">
An unreachable cluster has status running (RED-32805)
</h3>
<p>
When a cluster is in an unreachable state, the state is still
<code>
running
</code>
instead of being reported as an error.
</p>
<h3 id="readiness-probe-incorrect-on-failures-red-39300">
Readiness probe incorrect on failures (RED-39300)
</h3>
<p>
STS Readiness probe does not mark a node as "not ready" when running
<code>
rladmin status
</code>
on node failure.
</p>
<h3 id="role-missing-on-replica-sets-red-39002">
Role missing on replica sets (RED-39002)
</h3>
<p>
The
<code>
redis-enterprise-operator
</code>
role is missing permission on replica sets.
</p>
<h3 id="private-registries-are-not-supported-on-openshift-311-red-38579">
Private registries are not supported on OpenShift 3.11 (RED-38579)
</h3>
<p>
OpenShift 3.11 does not support DockerHub private registries. This is a known OpenShift issue.
</p>
<h3 id="internal-dns-and-kubernetes-dns-may-have-conflicts-red-37462">
Internal DNS and Kubernetes DNS may have conflicts (RED-37462)
</h3>
<p>
DNS conflicts are possible between the cluster
<code>
mdns_server
</code>
and the K8s DNS. This only impacts DNS resolution from within cluster nodes for Kubernetes DNS names.
</p>
<h3 id="5410-negatively-impacts-546-red-37233">
5.4.10 negatively impacts 5.4.6 (RED-37233)
</h3>
<p>
Kubernetes-based 5.4.10 deployments seem to negatively impact existing 5.4.6 deployments that share a Kubernetes cluster.
</p>
<h3 id="node-cpu-usage-is-reported-instead-of-pod-cpu-usage-red-36884">
Node CPU usage is reported instead of pod CPU usage (RED-36884)
</h3>
<p>
In Kubernetes, the node CPU usage we report on is the usage of the Kubernetes worker node hosting the REC pod.
</p>
<h3 id="clusters-must-be-named-rec-in-olm-based-deployments-red-39825">
Clusters must be named "rec" in OLM-based deployments (RED-39825)
</h3>
<p>
In OLM-deployed operators, the deployment of the cluster will fail if the name is not "rec". When the operator is deployed via the OLM, the security context constraints (scc) are bound to a specific service account name (i.e., "rec"). The workaround is to name the cluster "rec".
</p>
<h3 id="rec-clusters-fail-to-start-on-kubernetes-clusters-with-unsynchronized-clocks-red-47254">
REC clusters fail to start on Kubernetes clusters with unsynchronized clocks (RED-47254)
</h3>
<p>
When REC clusters are deployed on Kubernetes clusters with unsynchronized clocks, the REC cluster does not start correctly. The fix is to use NTP to synchronize the underlying K8s nodes.
</p>
<h3 id="deleting-an-openshift-project-with-an-rec-deployed-may-hang-red-47192">
Deleting an OpenShift project with an REC deployed may hang (RED-47192)
</h3>
<p>
When a REC cluster is deployed in a project (namespace) and has REDB resources, the
REDB resources must be deleted first before the REC can be deleted. As such, until the
REDB resources are deleted, the project deletion will hang. The fix is to delete the
REDB resources first and the REC second. Afterwards, you may delete the project.
</p>
<h3 id="rec-extralabels-are-not-applied-to-pvcs-on-k8s-versions-115-or-older-red-51921">
REC extraLabels are not applied to PVCs on K8s versions 1.15 or older (RED-51921)
</h3>
<p>
In K8s 1.15 or older, the PVC labels come from the match selectors and not the
PVC templates. As such, these versions cannot support PVC labels. If this feature
is required, the only fix is to upgrade the K8s cluster to a newer version.
</p>
<h3 id="hashicorp-vault-integration---no-support-for-gesher-red-55080">
Hashicorp Vault integration - no support for Gesher (RED-55080)
</h3>
<p>
There is no workaround at this time
</p>
<h3 id="rec-might-report-error-states-on-initial-startup-red-61707">
REC might report error states on initial startup (RED-61707)
</h3>
<p>
There is no workaround at this time except to ignore the errors.
</p>
<h3 id="pvc-size-issues-when-using-decimal-value-in-spec-red-62132">
PVC size issues when using decimal value in spec (RED-62132)
</h3>
<p>
The workaround for this issue is to make sure you use integer values for the PVC size.
</p>
<h3 id="following-old-revision-of-quick-start-guide-causes-issues-creating-an-redb-due-to-unrecognized-memory-field-name">
Following old revision of quick start guide causes issues creating an REDB due to unrecognized memory field name
</h3>
<p>
The workaround is to use the newer (current) revision of the quick start document available online.

<h1>
Data transformation
</h1>
<p>
The key functionality that Write-behind performs is mapping the data coming from
<a href="https://debezium.io/documentation/reference/stable/operations/debezium-server.html">
Debezium Server
</a>
(representing a Source Database row data or row state change) into a Redis key with a value of
<a href="/docs/latest/develop/data-types/hashes/">
Hash
</a>
or
<a href="/docs/latest/develop/data-types/json/">
JSON
</a>
.
There are two types of data transformations in Write-behind:
</p>
<ol>
<li>
<p>
By default, each source row is converted into one hash or one JSON key in Redis.
This conversion uses the Debezium schema-based conversion. The incoming data includes the schema and Write-behind uses a set of handlers to automatically convert each source column to a Redis Hash field or JSON type based on the Debezium type in the schema. See
<a href="/docs/latest/integrate/write-behind/reference/data-types-conversion/">
data type conversion
</a>
for a full reference on these conversions.
</p>
</li>
<li>
<p>
If the user wants to add or modify this default mapping, Write-behind provides declarative data transformations. These transformations are represented in YAML files. Each file contains a job, which is a set of transformations per source table. See
<a href="/docs/latest/integrate/write-behind/data-transformation/data-transformation-pipeline/">
declarative transformations
</a>
for more information.

JSON
</h3>
<p>
You can store or update vectors and any associated metadata in
<a href="/docs/latest/develop/data-types/json/">
JSON
</a>
using the
<a href="/docs/latest/commands/json.set/">
<code>
JSON.SET
</code>
</a>
command.
</p>
<p>
To store vectors in Redis as JSON, you store the vector as a JSON array of floats. Note that this differs from vector storage in Redis hashes, which are instead stored as raw bytes.
</p>
<p>
<strong>
Example
</strong>
</p>
<pre tabindex="0"><code>JSON.SET docs:01 $ '{"doc_embedding":[0.34,0.63,-0.54,-0.69,0.98,0.61], "category": "sports"}'
</code></pre>
<p>
One of the benefits of JSON is schema flexibility. As of v2.6.1, JSON supports multi-value indexing.
This allows you to index multiple vectors under the same
<a href="/docs/latest/develop/data-types/json/path/">
JSONPath
</a>
.
</p>
<p>
Here are some examples of multi-value indexing with vectors:
</p>
<p>
<strong>
Multi-value indexing example
</strong>
</p>
<pre tabindex="0"><code>JSON.SET docs:01 $ '{"doc_embedding":[[1,2,3,4], [5,6,7,8]]}'
JSON.SET docs:01 $ '{"chunk1":{"doc_embedding":[1,2,3,4]}, "chunk2":{"doc_embedding":[5,6,7,8]}}'
</code></pre>
<p>
Additional information and examples are available in the
<a href="/docs/latest/develop/interact/search-and-query/indexing/#index-json-arrays-as-vector">
Indexing JSON documents
</a>
section.
</p>
<h2 id="search-with-vectors">

<code>

</p>
<p>
To issue a vector search query with

<h3 id="vector-range-queries">
Vector range queries
</h3>
<p>
Vector range queries allow you to filter the index using a
<code>
radius
</code>
parameter representing the semantic distance between an input query vector and indexed vector fields. This is useful in scenarios when you don't know exactly how many nearest (
<code>
top_k
</code>
) neighbors to fetch, but you do know how similar the results should be.
</p>
<p>
For example, imagine a fraud or anomaly detection scenario where you aren't sure if there are any matches in the vector index. You can issue a vector range query to quickly check if there are any records of interest in the index within the specified radius.
</p>
<p>
Vector range queries operate slightly different than KNN vector queries:
</p>
<ul>
<li>
Vector range queries can appear multiple times in a query as filter criteria.
</li>
<li>
Vector range queries can be a part of the
<code>
<primary_filter_query>
</code>
in KNN vector search.
</li>
</ul>

Filters
</h3>
<p>
Redis supports vector searches that include filters to narrow the search space based on defined criteria. If your index contains searchable fields (for example,
<code>
TEXT
</code>
,
<code>
TAG
</code>
,
<code>
NUMERIC
</code>
,
<code>
GEO
</code>
,
<code>
GEOSHAPE
</code>
, and
<code>
VECTOR
</code>
), you can perform vector searches with filters.

</p>
<p>
<strong>
Syntax
</strong>
</p>
<p>
Vector search queries with filters follow this basic structure:
</p>
<pre tabindex="0"><code>FT.SEARCH <index_name> <primary_filter_query>=>[...]
</code></pre>
<p>
where
<code>
<primary_filter_query>
</code>
defines document selection and filtering.
</p>
<p>
<strong>
Example
</strong>
</p>
<pre tabindex="0"><code>FT.SEARCH documents "(@title:Sports @year:[2020 2022])=>[KNN 10 @doc_embedding $BLOB]" PARAMS 2 BLOB "\x12\xa9\xf5\x6c" DIALECT 4
</code></pre>
<h3 id="how-filtering-works">
How filtering works
</h3>
<p>
Redis uses internal algorithms to optimize the filtering computation for vector search.
The runtime algorithm is determined by heuristics that aim to minimize query latency based on several factors derived from the query and the index.
</p>
<p>
<strong>
Batches mode
</strong>
</p>
<p>
Batches mode works by paginating through small batches of nearest neighbors from the index:
</p>
<ul>
<li>
A batch of high-scoring documents from the vector index is retrieved. These documents are yielded only if the
<code>
<primary_filter_query>
</code>
is satisfied. In other words, the document must contain a similar vector and meet the filter criteria.
</li>
<li>
The iterative procedure terminates when
<code>
<top_k>
</code>
documents that pass the filter criteria are yielded, or after every vector in the index has been processed.
</li>
<li>
The batch size is determined automatically by heuristics based on
<code>
<top_k>
</code>
and the ratio between the expected number of documents in the index that pass the
<code>
<primary_filter_query>
</code>
and the vector index size.
</li>
<li>
The goal is to minimize the total number of batches required to get the
<code>
<top_k>
</code>
results while preserving the smallest batch size possible. Note that the batch size may change dynamically in each iteration based on the number of results that pass the filter in previous batches.
</li>
</ul>
<p>
<strong>
Ad-hoc brute force mode
</strong>
</p>
<ul>
<li>
The score of every vector corresponding to a document that passes the filter is computed, and the
<code>
<top_k>
</code>
results are selected and returned.
</li>
<li>
This approach is preferable when the number of documents passing the
<code>
<primary_filter_query>
</code>
is relatively small.
</li>
<li>
The results of the KNN query will always be accurate in this mode, even if the underlying vector index algorithm is an approximate one.
</li>
</ul>
<p>
The execution mode may switch from batch mode to ad-hoc brute-force mode during the run, based on updated estimations of relevant factors from one batch to another.

<li>
<p>
When performing a KNN vector search, you specify
<code>
<top_k>
</code>
nearest neighbors. However, the default Redis query
<code>
LIMIT
</code>
parameter (used for pagination) is 10. In order to get
<code>
<top_k>
</code>
returned results, you must also specify
<code>
LIMIT 0 <top_k>
</code>
in your search command. See examples below.
</p>
</li>
<li>
<p>
By default, the results are sorted by their document's score. To sort by vector similarity score, use
<code>
SORTBY <distance_field>
</code>
. See examples below.
</p>
</li>
<li>
<p>
Depending on your chosen distance metric, the calculated distance between vectors in an index have different bounds. For example,
<code>
Cosine
</code>
distance is bounded by
<code>
2
</code>
, while
<code>
L2
</code>
distance is not bounded. When performing a vector range query, the best practice is to adjust the
<code>
<radius>
</code>
parameter based on your use case and required recall or precision metrics.

Vector embeddings and vector search are not new concepts. Many of the largest companies have used
vectors to represent products in ecommerce catalogs or content in advertising pipelines for well over a decade.

With the emergence of Large Language Models (LLMs) and the proliferation of applications that require advanced information
retrieval techniques, Redis is well positioned to serve as your high performance query engine for semantic search and more.

<h1>
Discovery service
</h1>
<p>
The Discovery Service provides an IP-based connection management service
used when connecting to Redis Enterprise Software databases. When used
in conjunction with Redis Enterprise Software's other high availability
features, the Discovery Service assists an application scope with
topology changes such as adding, removing of nodes, node failovers and
so on. It does this by providing your application with the ability to
easily discover which node hosts the database endpoint. The API used for
discovery service is compliant with the Redis Sentinel API.
</p>
<p>
Discovery Service is an alternative for applications that do not want to
depend on DNS name resolution for their connectivity. Discovery Service
and DNS based connectivity are not mutually exclusive. They can be used
side by side in a given cluster where some clients can use Discovery
Service based connection while others can use DNS name resolution when
connecting to databases.
</p>
<h2 id="how-discovery-service-works">
How discovery service works
</h2>
<p>
The Discovery Service is available for querying on each node of the
cluster, listening on port 8001. To employ it, your application utilizes
a
<a href="/docs/latest/operate/rs/7.4/databases/connect/supported-clients-browsers/">
Redis Sentinel enabled client
library
</a>
to connect to the Discovery Service and request the endpoint for the
given database. The Discovery Service replies with the database's
endpoint for that database. In case of a node failure, the Discovery
Service is updated by the cluster manager with the new endpoint and
clients unable to connect to the database endpoint due to the failover,
can re-query the discovery service for the new endpoint for the
database.
</p>
<p>
The Discovery Service can return either the internal or external
endpoint for a database. If you query the discovery service for the
endpoint of a database named "db1", the Discovery Service returns
the external endpoint information by default. If only an internal
endpoint exists with no external endpoint the default behavior is to
return the internal endpoint. The "@internal" is added to the end of
the database name to explicitly ask for the internal endpoint. to query
the internal endpoint explicitly with database name "db1", you can pass
in the database name as "db1@internal".
</p>
<p>
If you'd like to examine the metadata returned from Redis Enterprise

It is important to note that, the Discovery Service is not a full
implementation of the
<a href="/docs/latest/operate/oss_and_stack/management/sentinel/">
Redis Sentinel
protocol
</a>
. There are aspects of the
protocol that are not applicable or would be duplication with existing
technology in Redis Enterprise Software. The Discovery Service
implements only the parts required to provide applications with easy
High Availability, be compatible with the protocol, and not rely on DNS
to derive which node in the cluster to communicate with.

<h1>
Manage Redis Enterprise databases for Kubernetes
</h1>
<p class="text-lg -mt-5 mb-10">
This section describes how the database controller provides the ability to create, manage, and use databases via a database custom resource.
</p>
<h2 id="redis-enterprise-database-redb-lifecycle">
Redis Enterprise database (REDB) lifecycle
</h2>
<p>
A Redis Enterprise database (REDB) is created with a custom resource file. The custom resource defines the size, name, and other specifications for the REDB. The database is created when you apply the custom resource file.
</p>
<p>
The database controller in Redis Enterprise for Kubernetes:
</p>
<ul>
<li>
Discovers the custom resource
</li>
<li>
Makes sure the REDB is created in the same namespace as the Redis Enterprise cluster (REC)
</li>
<li>
Maintains consistency between the custom resource and the REDB
</li>
</ul>
<p>
The database controller recognizes the new custom resource and validates the specification.
If valid, the controller combines the values specified in
the custom resource with default values to create a full specification. It then uses this full specification to create the
database on the specified Redis Enterprise cluster (REC).
</p>
<p>
Once the database is created, it is exposed with the same service mechanisms by the service rigger for the Redis Enterprise cluster.
If the database
<a href="/docs/latest/operate/kubernetes/delete-custom-resources/">
custom resource is deleted
</a>
, the database and its services are deleted from the cluster.
</p>
<h3 id="flexible-deployment-options">
Flexible deployment options

<p>
Databases in multiple namespaces can be managed by the same operator. To learn more, see
<a href="/docs/latest/operate/kubernetes/re-clusters/multi-namespace/">
Manage databases in multiple namespaces

</p>
<h2 id="create-a-database">
Create a database
</h2>
<p>
Your Redis Enterprise database custom resource must be of the
<code>
kind: RedisEnterpriseDatabase
</code>
and have values for
<code>
name
</code>
and
<code>
memorySize
</code>
. All other values are optional and will be defaults if not specified.
</p>
<ol>
<li>
<p>
Create a file (in this example mydb.yaml) that contains your database custom resource.
</p>

</div>
<p>
To create a REDB in a different namespace from your REC, you need to specify the cluster with
<code>
redisEnterpriseCluster
</code>
in the
<code>
spec
</code>
section of your RedisEnterpriseDatabase custom resource.
</p>
<div class="highlight">

</span></span></code></pre>
</div>
<p>
When the status is
<code>
active
</code>
, the database is ready to use.
</p>
</li>
</ol>
<h2 id="modify-a-database">
Modify a database
</h2>
<p>
The custom resource defines the properties of the database.
To change the database, you can edit your original specification and apply the change or use
<code>
kubectl edit
</code>
.
</p>
<p>
To modify the database:
</p>
<ol>
<li>
<p>
Edit the definition:
</p>
<div class="highlight">

</span></span></code></pre>
</div>
</li>
<li>
<p>
Change the specification (only properties in
<code>

section) and save the changes.

, the database is ready for use.
</p>
</li>
</ol>
<h2 id="delete-a-database">
Delete a database
</h2>
<p>
The database exists as long as the custom resource exists.
If you delete the custom resource, the database controller deletes the database.
The database controller removes the database and its services from the cluster.
</p>
<p>
To delete a database, run:
</p>
<div class="highlight">
<pre class="chroma"><code class="language-sh" data-lang="sh"><span class="line"><span class="cl">kubectl delete redb mydb
</span></span></code></pre>
</div>
<h2 id="connect-to-a-database">
Connect to a database
</h2>
<p>
After the database controller creates a database, the services for accessing the database are created in the same namespace. By default there are two services, one 'ClusterIP' service and one 'headless' service.
<br/>
Connection information for the database is stored in a Kubernetes
<a href="https://kubernetes.io/docs/concepts/configuration/secret/">
secret
</a>
maintained by the database controller. This secret contains:
</p>
<ul>
<li>
The database port (
<code>
port
</code>
)
</li>
<li>
A comma separated list of service names (
<code>
service_names
</code>
)
</li>
<li>
The database password for authenticating (
<code>
password
</code>
)
</li>
</ul>
<p>
The name of that secret is stored in the database custom resource.

Considerations
</h2>
<p>
You can use Transit Gateway as an alternative to
<a href="/docs/latest/operate/rc/security/vpc-peering/">
VPC peering
</a>
, or you can enable both for your subscription.
</p>
<p>
Compared to VPC peering, Transit Gateway:
</p>
<ul>
<li>
<p>
Supports complex network topologies, such as multiple VPCs or site-to-site VPNs.
</p>
</li>
<li>
<p>
Uses security groups and network ACLs to control traffic between VPCs.
</p>
</li>
<li>
<p>
Has a higher network latency and cost than VPC peering due to Transit Gateway infrastructure costs.
</p>
</li>
</ul>
<p>
Consider using VPC peering and Transit Gateway in parallel for the following situations:
</p>
<ul>
<li>
<p>
When migrating from one connectivity solution to the other.
</p>
</li>
<li>
<p>
If different applications need to connect to the same database but have different latency or security requirements.
</p>
</li>
</ul>

Redis sets

<p class="text-lg -mt-5 mb-10">
Introduction to Redis sets
</p>
<p>
A Redis set is an unordered collection of unique strings (members).
You can use Redis sets to efficiently:
</p>
<ul>
<li>
Track unique items (e.g., track all unique IP addresses accessing a given blog post).
</li>
<li>
Represent relations (e.g., the set of all users with a given role).
</li>
<li>
Perform common set operations such as intersection, unions, and differences.
</li>
</ul>
<h2 id="basic-commands">
Basic commands
</h2>
<ul>
<li>
<a href="/docs/latest/commands/sadd/">
<code>
SADD
</code>
</a>
adds a new member to a set.
</li>
<li>
<a href="/docs/latest/commands/srem/">
<code>
SREM
</code>
</a>
removes the specified member from the set.
</li>
<li>
<a href="/docs/latest/commands/sismember/">
<code>
SISMEMBER
</code>
</a>
tests a string for set membership.
</li>
<li>
<a href="/docs/latest/commands/sinter/">
<code>
SINTER
</code>
</a>
returns the set of members that two or more sets have in common (i.e., the intersection).
</li>
<li>
<a href="/docs/latest/commands/scard/">
<code>
SCARD
</code>
</a>
returns the size (a.k.a. cardinality) of a set.
</li>
</ul>
<p>
See the
<a href="/docs/latest/commands/?group=set">
complete list of set commands
</a>
.
</p>
<h2 id="examples">
Examples
</h2>
<ul>
<li>
<p>
Store the sets of bikes racing in France and the USA. Note that

You'll note that the
<a href="/docs/latest/commands/sdiff/">
<code>
SDIFF
</code>
</a>
command returns an empty array when the
difference between all sets is empty. You'll also note that the order of sets
passed to
<a href="/docs/latest/commands/sdiff/">
<code>
SDIFF
</code>
</a>
matters, since the difference is not commutative.
</p>
<p>
When you want to remove items from a set, you can use the
<a href="/docs/latest/commands/srem/">
<code>
SREM
</code>
</a>
command to
remove one or more items from a set, or you can use the
<a href="/docs/latest/commands/spop/">
<code>
SPOP
</code>
</a>
command to
remove a random item from a set. You can also
<em>
return
</em>
a random item from a
set without removing it using the
<a href="/docs/latest/commands/srandmember/">
<code>
SRANDMEMBER
</code>

<p>
The max size of a Redis set is 2^32 - 1 (4,294,967,295) members.
</p>
<h2 id="performance">
Performance
</h2>
<p>
Most set operations, including adding, removing, and checking whether an item is a set member, are O(1).
This means that they're highly efficient.
However, for large sets with hundreds of thousands of members or more, you should exercise caution when running the
<a href="/docs/latest/commands/smembers/">
<code>
SMEMBERS
</code>
</a>
command.
This command is O(n) and returns the entire set in a single response.
As an alternative, consider the
<a href="/docs/latest/commands/sscan/">
<code>
SSCAN
</code>
</a>
, which lets you retrieve all members of a set iteratively.
</p>
<h2 id="alternatives">
Alternatives
</h2>
<p>
Sets membership checks on large datasets (or on streaming data) can use a lot of memory.
If you're concerned about memory usage and don't need perfect precision, consider a
<a href="/docs/latest/develop/data-types/probabilistic/bloom-filter/">
Bloom filter or Cuckoo filter
</a>
as an alternative to a set.
</p>
<p>
Redis sets are frequently used as a kind of index.
If you need to index and query your data, consider the
<a href="/docs/latest/develop/data-types/json/">
JSON
</a>
data type and the
<a href="/docs/latest/develop/interact/search-and-query/">
Redis Query Engine
</a>
features.

Redis benchmark
</h1>
<p class="text-lg -mt-5 mb-10">
Use the redis-benchmark utility on a Redis server
</p>
<h2 id="how-fast-is-redis">
How fast is Redis?
</h2>
<p>
Redis includes the
<code>
redis-benchmark
</code>
utility that simulates running commands done
by N clients at the same time sending M total queries (it is similar to the
Apache's
<code>
ab
</code>
utility). Below you'll find the full output of a benchmark executed
against a Linux box.
</p>
<p>
The following options are supported:
</p>
<pre><code>Usage: redis-benchmark [-h <host>] [-p <port>] [-c <clients>] [-n <requests]> [-k <boolean>]
-h <hostname> Server hostname (default 127.0.0.1)
-p <port> Server port (default 6379)
-s <socket> Server socket (overrides host and port)
-a <password> Password for Redis Auth
--user <username> Used to send ACL style 'AUTH username pass'. Needs -a.
-c <clients> Number of parallel connections (default 50)
-n <requests> Total number of requests (default 100000)
-d <size> Data size of SET/GET value in bytes (default 3)
--dbnum <db> SELECT the specified db number (default 0)
--threads <num> Enable multi-thread mode.
--cluster Enable cluster mode.
--enable-tracking Send CLIENT TRACKING on before starting benchmark.
-k <boolean> 1=keep alive 0=reconnect (default 1)
-r <keyspacelen> Use random keys for SET/GET/INCR, random values for
SADD, random members and scores for ZADD.
Using this option the benchmark will expand the string
__rand_int__ inside an argument with a 12 digits number
in the specified range from 0 to keyspacelen-1. The
substitution changes every time a command is executed.
Default tests use this to hit random keys in the
specified range.
-P <numreq> Pipeline <numreq> requests. Default 1 (no pipeline).
-e If server replies with errors, show them on stdout.
(No more than 1 error per second is displayed.)
-q Quiet. Just show query/sec values
--precision Number of decimal places to display in latency output (default 0)
--csv Output in CSV format
-l Loop. Run the tests forever
-t <tests> Only run the comma separated list of tests. The test
names are the same as the ones produced as output.
-I Idle mode. Just open N idle connections and wait.
--help Output this help and exit.
--version Output version and exit.
</code></pre>
<p>
You need to have a running Redis instance before launching the benchmark.
A typical example would be:
</p>
<pre><code>redis-benchmark -q -n 100000
</code></pre>
<p>
Using this tool is quite easy, and you can also write your own benchmark,
but as with any benchmarking activity, there are some pitfalls to avoid.
</p>
<h2 id="running-only-a-subset-of-the-tests">
Running only a subset of the tests
</h2>
<p>
You don't need to run all the default tests every time you execute redis-benchmark.
The simplest thing to select only a subset of tests is to use the
<code>
-t
</code>
option
like in the following example:
</p>
<pre><code>$ redis-benchmark -t set,lpush -n 100000 -q
SET: 180180.17 requests per second, p50=0.143 msec
LPUSH: 188323.91 requests per second, p50=0.135 msec
</code></pre>
<p>
In the above example we asked to just run test the SET and LPUSH commands,
in quiet mode (see the
<code>
-q
</code>
switch).
</p>
<p>
It is also possible to specify the command to benchmark directly like in the
following example:
</p>
<pre><code>$ redis-benchmark -n 100000 -q script load "redis.call('set','foo','bar')"
script load redis.call('set','foo','bar'): 69881.20 requests per second
</code></pre>
<h2 id="selecting-the-size-of-the-key-space">
Selecting the size of the key space
</h2>
<p>
By default the benchmark runs against a single key. In Redis the difference
between such a synthetic benchmark and a real one is not huge since it is an
in-memory system, however it is possible to stress cache misses and in general
to simulate a more real-world work load by using a large key space.
</p>
<p>
This is obtained by using the
<code>
-r
</code>
switch. For instance if I want to run
one million SET operations, using a random key for every operation out of
100k possible keys, I'll use the following command line:
</p>
<pre><code>$ redis-cli flushall
OK
$ redis-benchmark -t set -r 100000 -n 1000000
====== SET ======
1000000 requests completed in 13.86 seconds
50 parallel clients
3 bytes payload
keep alive: 1
99.76% `<=` 1 milliseconds
99.98% `<=` 2 milliseconds
100.00% `<=` 3 milliseconds
100.00% `<=` 3 milliseconds
72144.87 requests per second
$ redis-cli dbsize
(integer) 99993
</code></pre>
<h2 id="using-pipelining">
Using pipelining
</h2>
<p>
By default every client (the benchmark simulates 50 clients if not otherwise
specified with
<code>
-c
</code>
) sends the next command only when the reply of the previous
command is received, this means that the server will likely need a read call
in order to read each command from every client. Also RTT is paid as well.
</p>
<p>
Redis supports
<a href="/topics/pipelining">
pipelining
</a>
, so it is possible to send
multiple commands at once, a feature often exploited by real world applications.
Redis pipelining is able to dramatically improve the number of operations per
second a server is able do deliver.
</p>
<p>
This is an example of running the benchmark in a MacBook Air 11" using a
pipelining of 16 commands:
</p>
<pre><code>$ redis-benchmark -n 1000000 -t set,get -P 16 -q
SET: 1536098.25 requests per second, p50=0.479 msec
GET: 1811594.25 requests per second, p50=0.391 msec
</code></pre>
<p>
Using pipelining results in a significant increase in performance.
</p>
<h2 id="pitfalls-and-misconceptions">
Pitfalls and misconceptions
</h2>
<p>
The first point is obvious: the golden rule of a useful benchmark is to
only compare apples and apples. Different versions of Redis can be compared
on the same workload for instance. Or the same version of Redis, but with
different options. If you plan to compare Redis to something else, then it is
important to evaluate the functional and technical differences, and take them
in account.
</p>
<ul>
<li>
Redis is a server: all commands involve network or IPC round trips. It is meaningless to compare it to embedded data stores such as SQLite, Berkeley DB, Tokyo/Kyoto Cabinet, etc ... because the cost of most operations is primarily in network/protocol management.
</li>
<li>
Redis commands return an acknowledgment for all usual commands. Some other data stores do not. Comparing Redis to stores involving one-way queries is only mildly useful.
</li>
<li>
Naively iterating on synchronous Redis commands does not benchmark Redis itself, but rather measure your network (or IPC) latency and the client library intrinsic latency. To really test Redis, you need multiple connections (like redis-benchmark) and/or to use pipelining to aggregate several commands and/or multiple threads or processes.
</li>
<li>
Redis is an in-memory data store with some optional persistence options. If you plan to compare it to transactional servers (MySQL, PostgreSQL, etc ...), then you should consider activating AOF and decide on a suitable fsync policy.
</li>
<li>
Redis is, mostly, a single-threaded server from the POV of commands execution (actually modern versions of Redis use threads for different things). It is not designed to benefit from multiple CPU cores. People are supposed to launch several Redis instances to scale out on several cores if needed. It is not really fair to compare one single Redis instance to a multi-threaded data store.
</li>
</ul>
<p>
A common misconception is that redis-benchmark is designed to make Redis
performances look stellar, the throughput achieved by redis-benchmark being
somewhat artificial, and not achievable by a real application. This is
actually not true.
</p>
<p>
The
<code>
redis-benchmark
</code>
program is a quick and useful way to get some figures and
evaluate the performance of a Redis instance on a given hardware. However,
by default, it does not represent the maximum throughput a Redis instance can
sustain. Actually, by using pipelining and a fast client (hiredis), it is fairly
easy to write a program generating more throughput than redis-benchmark. The
default behavior of redis-benchmark is to achieve throughput by exploiting
concurrency only (i.e. it creates several connections to the server).
It does not use pipelining or any parallelism at all (one pending query per
connection at most, and no multi-threading), if not explicitly enabled via
the
<code>
-P
</code>
parameter. So in some way using
<code>
redis-benchmark
</code>
and, triggering, for
example, a
<code>
BGSAVE
</code>
operation in the background at the same time, will provide
the user with numbers more near to the
<em>
worst case
</em>
than to the best case.
</p>
<p>
To run a benchmark using pipelining mode (and achieve higher throughput),
you need to explicitly use the -P option. Please note that it is still a
realistic behavior since a lot of Redis based applications actively use
pipelining to improve performance. However you should use a pipeline size that
is more or less the average pipeline length you'll be able to use in your
application in order to get realistic numbers.
</p>
<p>
Finally, the benchmark should apply the same operations, and work in the same way
with the multiple data stores you want to compare. It is absolutely pointless to
compare the result of redis-benchmark to the result of another benchmark
program and extrapolate.
</p>
<p>
For instance, Redis and memcached in single-threaded mode can be compared on
GET/SET operations. Both are in-memory data stores, working mostly in the same
way at the protocol level. Provided their respective benchmark application is
aggregating queries in the same way (pipelining) and use a similar number of
connections, the comparison is actually meaningful.
</p>
<p>
This perfect example is illustrated by the dialog between Redis (antirez) and
memcached (dormando) developers.
</p>
<p>
<a href="http://antirez.com/post/redis-memcached-benchmark.html">
antirez 1 - On Redis, Memcached, Speed, Benchmarks and The Toilet
</a>
</p>
<p>
<a href="http://dormando.livejournal.com/525147.html">

</p>
<p>
<a href="http://antirez.com/post/update-on-memcached-redis-benchmark.html">
antirez 2 - An update on the Memcached/Redis benchmark
</a>
</p>
<p>
You can see that in the end, the difference between the two solutions is not
so staggering, once all technical aspects are considered. Please note both
Redis and memcached have been optimized further after these benchmarks.
</p>
<p>
Finally, when very efficient servers are benchmarked (and stores like Redis
or memcached definitely fall in this category), it may be difficult to saturate
the server. Sometimes, the performance bottleneck is on client side,
and not server-side. In that case, the client (i.e. the benchmark program itself)
must be fixed, or perhaps scaled out, in order to reach the maximum throughput.
</p>
<h2 id="factors-impacting-redis-performance">
Factors impacting Redis performance
</h2>
<p>
There are multiple factors having direct consequences on Redis performance.
We mention them here, since they can alter the result of any benchmarks.
Please note however, that a typical Redis instance running on a low end,
untuned box usually provides good enough performance for most applications.
</p>
<ul>
<li>
Network bandwidth and latency usually have a direct impact on the performance.
It is a good practice to use the ping program to quickly check the latency
between the client and server hosts is normal before launching the benchmark.
Regarding the bandwidth, it is generally useful to estimate
the throughput in Gbit/s and compare it to the theoretical bandwidth
of the network. For instance a benchmark setting 4 KB strings
in Redis at 100000 q/s, would actually consume 3.2 Gbit/s of bandwidth
and probably fit within a 10 Gbit/s link, but not a 1 Gbit/s one. In many real
world scenarios, Redis throughput is limited by the network well before being
limited by the CPU. To consolidate several high-throughput Redis instances
on a single server, it worth considering putting a 10 Gbit/s NIC
or multiple 1 Gbit/s NICs with TCP/IP bonding.
</li>
<li>
CPU is another very important factor. Being single-threaded, Redis favors
fast CPUs with large caches and not many cores. At this game, Intel CPUs are
currently the winners. It is not uncommon to get only half the performance on
an AMD Opteron CPU compared to similar Nehalem EP/Westmere EP/Sandy Bridge
Intel CPUs with Redis. When client and server run on the same box, the CPU is
the limiting factor with redis-benchmark.
</li>
<li>
Speed of RAM and memory bandwidth seem less critical for global performance
especially for small objects. For large objects (>10 KB), it may become
noticeable though. Usually, it is not really cost-effective to buy expensive
fast memory modules to optimize Redis.
</li>
<li>
Redis runs slower on a VM compared to running without virtualization using
the same hardware. If you have the chance to run Redis on a physical machine
this is preferred. However this does not mean that Redis is slow in
virtualized environments, the delivered performances are still very good
and most of the serious performance issues you may incur in virtualized
environments are due to over-provisioning, non-local disks with high latency,
or old hypervisor software that have slow
<code>
fork
</code>
syscall implementation.
</li>
<li>
When the server and client benchmark programs run on the same box, both
the TCP/IP loopback and unix domain sockets can be used. Depending on the
platform, unix domain sockets can achieve around 50% more throughput than
the TCP/IP loopback (on Linux for instance). The default behavior of
redis-benchmark is to use the TCP/IP loopback.
</li>
<li>
The performance benefit of unix domain sockets compared to TCP/IP loopback
tends to decrease when pipelining is heavily used (i.e. long pipelines).
</li>
<li>
When an ethernet network is used to access Redis, aggregating commands using
pipelining is especially efficient when the size of the data is kept under
the ethernet packet size (about 1500 bytes). Actually, processing 10 bytes,
100 bytes, or 1000 bytes queries almost result in the same throughput.
See the graph below.
</li>
</ul>
<p>
<img alt="Data size impact" src="https://github.com/dspezia/redis-doc/raw/client_command/topics/Data_size.png"/>
</p>
<ul>
<li>
On multi CPU sockets servers, Redis performance becomes dependent on the
NUMA configuration and process location. The most visible effect is that
redis-benchmark results seem non-deterministic because client and server
processes are distributed randomly on the cores. To get deterministic results,
it is required to use process placement tools (on Linux: taskset or numactl).
The most efficient combination is always to put the client and server on two
different cores of the same CPU to benefit from the L3 cache.
Here are some results of 4 KB SET benchmark for 3 server CPUs (AMD Istanbul,
Intel Nehalem EX, and Intel Westmere) with different relative placements.
Please note this benchmark is not meant to compare CPU models between themselves
(CPUs exact model and frequency are therefore not disclosed).
</li>
</ul>
<p>
<img alt="NUMA chart" src="https://github.com/dspezia/redis-doc/raw/6374a07f93e867353e5e946c1e39a573dfc83f6c/topics/NUMA_chart.gif"/>
</p>
<ul>
<li>
With high-end configurations, the number of client connections is also an
important factor. Being based on epoll/kqueue, the Redis event loop is quite
scalable. Redis has already been benchmarked at more than 60000 connections,
and was still able to sustain 50000 q/s in these conditions. As a rule of thumb,
an instance with 30000 connections can only process half the throughput
achievable with 100 connections. Here is an example showing the throughput of
a Redis instance per number of connections:
</li>
</ul>
<p>
<img alt="connections chart" src="https://github.com/dspezia/redis-doc/raw/system_info/topics/Connections_chart.png"/>
</p>
<ul>
<li>
With high-end configurations, it is possible to achieve higher throughput by
tuning the NIC(s) configuration and associated interruptions. Best throughput
is achieved by setting an affinity between Rx/Tx NIC queues and CPU cores,
and activating RPS (Receive Packet Steering) support. More information in this
<a href="https://groups.google.com/forum/#!msg/redis-db/gUhc19gnYgc/BruTPCOroiMJ">
thread
</a>
.
Jumbo frames may also provide a performance boost when large objects are used.
</li>
<li>
Depending on the platform, Redis can be compiled against different memory
allocators (libc malloc, jemalloc, tcmalloc), which may have different behaviors
in term of raw speed, internal and external fragmentation.
If you did not compile Redis yourself, you can use the INFO command to check
the
<code>
mem_allocator
</code>
field. Please note most benchmarks do not run long enough to
generate significant external fragmentation (contrary to production Redis
instances).
</li>
</ul>
<h2 id="other-things-to-consider">
Other things to consider
</h2>
<p>
One important goal of any benchmark is to get reproducible results, so they
can be compared to the results of other tests.
</p>
<ul>
<li>
A good practice is to try to run tests on isolated hardware as much as possible.
If it is not possible, then the system must be monitored to check the benchmark
is not impacted by some external activity.
</li>
<li>
Some configurations (desktops and laptops for sure, some servers as well)
have a variable CPU core frequency mechanism. The policy controlling this
mechanism can be set at the OS level. Some CPU models are more aggressive than
others at adapting the frequency of the CPU cores to the workload. To get
reproducible results, it is better to set the highest possible fixed frequency
for all the CPU cores involved in the benchmark.
</li>
<li>
An important point is to size the system accordingly to the benchmark.
The system must have enough RAM and must not swap. On Linux, do not forget
to set the
<code>
overcommit_memory
</code>
parameter correctly. Please note 32 and 64 bit
Redis instances do not have the same memory footprint.
</li>
<li>
If you plan to use RDB or AOF for your benchmark, please check there is no other
I/O activity in the system. Avoid putting RDB or AOF files on NAS or NFS shares,
or on any other devices impacting your network bandwidth and/or latency
(for instance, EBS on Amazon EC2).
</li>
<li>
Set Redis logging level (loglevel parameter) to warning or notice. Avoid putting
the generated log file on a remote filesystem.
</li>
<li>
Avoid using monitoring tools which can alter the result of the benchmark. For
instance using INFO at regular interval to gather statistics is probably fine,
but MONITOR will impact the measured performance significantly.
</li>
</ul>
<h2 id="benchmark-results-on-bare-metal-servers-across-different-redis-versions">
Benchmark results on bare-metal servers across different Redis versions
</h2>
<p>
It is critically important that Redis performance is retained or improved seamlessly on every released version.
</p>
<p>
To assess it, we've conducted benchmarks on the released versions of Redis (starting on v2.6.0) using
<code>
redis-benchmark
</code>
on a series of command types over a standalone redis-server, repeating the same benchmark multiple times, ensuring its statistical significance, and measuring the run-to-run variance.
</p>
<p>
The used hardware platform was a stable bare-metal HPE ProLiant DL380 Gen10 Server, with one Intel(R) Xeon(R) Gold 6230 CPU @ 2.10GHz, disabling Intel HT Technology, disabling CPU Frequency scaling, with all configurable BIOS and CPU system settings set to performance.
</p>
<p>
The box was running Ubuntu 18.04 Linux release 4.15.0-123, and Redis was compiled with gcc 7.5.0.
The used benchmark client (
<code>
redis-benchmark
</code>
) was kept stable across all tests, with version
<code>
redis-benchmark 6.2.0 (git:445aa844)
</code>
.
Both the redis-server and redis-benchmark processes were pinned to specific physical cores.
</p>
<p>
The following benchmark options were used across tests:
</p>
<ul>
<li>
The tests were done with 50 simultaneous clients performing 5 million requests.
</li>
<li>
Tests were executed using the loopback interface.
</li>
<li>
Tests were executed without pipelining.
</li>
<li>
The used payload size was 256 Bytes.
</li>
<li>
For each redis-benchmark process, 2 threads were used to ensure that the benchmark client was not the bottleneck.
</li>
<li>
Strings, Hashes, Sets, and Sorted Sets data types were benchmarked.
</li>
</ul>
<p>
Below we present the obtained results, broken by data type.

<p>
This command blocks the current client until all the previous write commands
are successfully transferred and acknowledged by at least the number
of replicas you specify in the
<code>
numreplicas
</code>
argument. If the value
you specify for the
<code>
timeout
</code>
argument (in milliseconds) is reached, the command
returns even if the specified number of replicas were not yet reached.
</p>
<p>
The command
<strong>
will always return
</strong>
the number of replicas that acknowledged
the write commands sent by the current client before the
<code>
WAIT
</code>
command, both in the case where
the specified number of replicas are reached, or when the timeout is reached.
</p>
<p>
A few remarks:
</p>
<ol>
<li>
When
<code>
WAIT
</code>
returns, all the previous write commands sent in the context of the current connection are guaranteed to be received by the number of replicas returned by
<code>
WAIT
</code>
.
</li>
<li>
If the command is sent as part of a
<a href="/docs/latest/commands/multi/">
<code>
MULTI
</code>
</a>
transaction (since Redis 7.0, any context that does not allow blocking, such as inside scripts), the command does not block but instead just return ASAP the number of replicas that acknowledged the previous write commands.
</li>
<li>
A timeout of 0 means to block forever.
</li>
<li>
Since
<code>
WAIT
</code>
returns the number of replicas reached both in case of failure and success, the client should check that the returned value is equal or greater to the replication level it demanded.
</li>
</ol>
<h2 id="consistency-and-wait">
Consistency and WAIT
</h2>
<p>
Note that
<code>
WAIT
</code>
does not make Redis a strongly consistent store: while synchronous replication is part of a replicated state machine, it is not the only thing needed. However in the context of Sentinel or Redis Cluster failover,
<code>
WAIT
</code>
improves the real world data safety.
</p>
<p>
Specifically if a given write is transferred to one or more replicas, it is more likely (but not guaranteed) that if the master fails, we'll be able to promote, during a failover, a replica that received the write: both Sentinel and Redis Cluster will do a best-effort attempt to promote the best replica among the set of available replicas.
</p>
<p>
However this is just a best-effort attempt so it is possible to still lose a write synchronously replicated to multiple replicas.
</p>
<h2 id="implementation-details">
Implementation details
</h2>
<p>
Since the introduction of partial resynchronization with replicas (PSYNC feature) Redis replicas asynchronously ping their master with the offset they already processed in the replication stream. This is used in multiple ways:
</p>
<ol>
<li>
Detect timed out replicas.
</li>
<li>
Perform a partial resynchronization after a disconnection.
</li>
<li>
Implement
<code>
WAIT
</code>
.
</li>
</ol>
<p>
In the specific case of the implementation of
<code>
WAIT
</code>
, Redis remembers, for each client, the replication offset of the produced replication stream when a given
write command was executed in the context of a given client. When
<code>
WAIT
</code>
is
called Redis checks if the specified number of replicas already acknowledged
this offset or a greater one.
</p>
<h2 id="examples">
Examples
</h2>
<pre tabindex="0"><code>> SET foo bar
OK
> WAIT 1 0
(integer) 1
> WAIT 2 1000
(integer) 1
</code></pre>
<p>
In the following example the first call to
<code>

unblocks and returns 1, the number of replicas reached.

<h1>
Enable Private Service Connect
</h1>
<p class="text-lg -mt-5 mb-10">
Private Service Connect creates a private endpoint that allows secure connections to Redis Cloud databases without exposing your application VPC.
</p>
<p>
<a href="https://cloud.google.com/vpc/docs/private-service-connect">
Private Service Connect
</a>
(PSC) creates a private endpoint that allows secure connections to Redis Cloud databases without exposing your application's
<a href="https://en.wikipedia.org/wiki/Virtual_private_cloud">
virtual private cloud
</a>
(VPC).
</p>
<p>
This feature is only available for Redis Cloud Pro subscriptions hosted on Google Cloud.
</p>
<h2 id="considerations">
Considerations
</h2>
<p>
You can use Private Service Connect as an alternative to
<a href="/docs/latest/operate/rc/security/vpc-peering/">
VPC peering
</a>
, or you can enable both for your subscription.
</p>
<p>
Compared to VPC peering, Private Service Connect:
</p>
<ul>
<li>
<p>
Only exposes the private endpoint instead of the entire application VPC network.
</p>
</li>
<li>
<p>
Allows producer (Redis Cloud VPC) and consumer (application VPC) CIDR ranges to overlap.
</p>
</li>
<li>
<p>
Has slightly higher network latency than VPC peering due to load balancing requirements.
</p>

</div>
<div class="p-1 pl-6 border-l border-l-redis-ink-900 border-opacity-50">
<div class="font-medium">
Note:
</div>
Larger clusters are more likely to experience increased latency with Private Service Connect versus VPC peering.
</div>
</div>
</li>
</ul>
<p>
Consider using VPC peering and Private Service Connect in parallel for the following situations:
</p>
<ul>
<li>
<p>
When migrating from one connectivity solution to the other.
</p>
</li>
<li>
<p>
If different applications need to connect to the same database but have different latency or security requirements.
</p>
</li>
</ul>
<h2 id="setup-psc">
Set up Private Service Connect
</h2>
<p>
To set up Private Service Connect, you need to:
</p>

Limitations
</h2>
<p>
Private Service Connect has the following limitations in Redis Cloud:
</p>
<ul>
<li>
<p>
Although Redis Cloud supports using Private Service Connect with Enterprise clustering, you cannot use the
<a href="/docs/latest/operate/rc/databases/create-database/#oss-cluster-api">
Cluster API
</a>
with Private Service Connect enabled.
</p>
</li>
<li>
<p>
Private Service Connect is not available for clusters with Redis versions 6.2.12 and earlier. Contact
<a href="https://redis.io/support">
Redis support
</a>
to upgrade the cluster to a compatible version or
<a href="/docs/latest/operate/rc/databases/create-database/create-pro-database-new/">

In order to add or remove instances, you must use this API. For simple configuration updates, it is recommended to use PATCH on /crdbs/{crdb_guid} instead.

Updating default_db_config affects both existing and new instances that may be added.

When you update db_config, it changes the configuration of the database that you specify. This field overrides corresponding fields (if any) in default_db_config.
