langchain.storage.redis.RedisStore¶
class langchain.storage.redis.RedisStore(*, client: Any = None, redis_url: Optional[str] = None, client_kwargs: Optional[dict] = None, ttl: Optional[int] = None, namespace: Optional[str] = None)[source]¶
BaseStore implementation using Redis as the underlying store.
Examples
Create a RedisStore instance and perform operations on it:
# Instantiate the RedisStore with a Redis connection
from langchain.storage import RedisStore
from langchain.utilities.redis import get_client
client = get_client('redis://localhost:6379')
redis_store = RedisStore(client)
# Set values for keys
redis_store.mset([("key1", b"value1"), ("key2", b"value2")])
# Get values for keys
values = redis_store.mget(["key1", "key2"])
# [b"value1", b"value2"]
# Delete keys
redis_store.mdelete(["key1"])
# Iterate over keys
for key in redis_store.yield_keys():
    print(key)
Initialize the RedisStore with a Redis connection.
Must provide either a Redis client or a redis_url with optional client_kwargs.
Parameters
client – A Redis connection instance
redis_url – redis url
client_kwargs – Keyword arguments to pass to the Redis client
ttl – time to expire keys in seconds if provided,
if None keys will never expire
namespace – if provided, all keys will be prefixed with this namespace
Methods
__init__(*[, client, redis_url, ...])
Initialize the RedisStore with a Redis connection.
mdelete(keys)
Delete the given keys.
mget(keys)
Get the values associated with the given keys.
mset(key_value_pairs)
Set the given key-value pairs.
yield_keys(*[, prefix])
Yield keys in the store.
