After the schema change, the company implements the <strong> Schema Versioning </strong> pattern, and adds a <code class="leafygreen-ui-1l06pbn"> schemaVersion </code> field to tell the application how it should query each document. </p> </li> </ul> </section> <section> <h2 class="contains-headerlink leafygreen-ui-19f71ei" weight="medium"> Tasks <a class="headerlink leafygreen-ui-1kepx47" href="#tasks" title="Permalink to this heading"> <svg aria-label="Link Icon" class="leafygreen-ui-a30zj9" fill="none" height="12" role="img" viewbox="0 0 16 16" width="12" xmlns="http://www.w3.org/2000/svg"> <path d="M6.039 9.953a3.596 3.596 0 0 1-.327-.38l1.45-1.445a1.553 1.553 0 0 0 2.496.423l2.885-2.87a1.57 1.57 0 0 0 .01-2.213 1.553 1.553 0 0 0-2.203-.01l-.379.377A.995.995 0 0 1 8.56 3.83a1.005 1.005 0 0 1 .006-1.418l.38-.377a3.542 3.542 0 0 1 5.024.023 3.58 3.58 0 0 1-.022 5.047l-2.884 2.871a3.542 3.542 0 0 1-5.025-.022Z" fill="currentColor"> </path> <path d="M9.961 6.047c.12.12.228.248.327.38l-1.45 1.445a1.553 1.553 0 0 0-2.496-.423l-2.885 2.87a1.57 1.57 0 0 0-.01 2.213 1.553 1.553 0 0 0 2.203.01l.379-.377a.995.995 0 0 1 1.411.006 1.005 1.005 0 0 1-.006 1.418l-.38.377a3.542 3.542 0 0 1-5.024-.023 3.58 3.58 0 0 1 .022-5.047l2.884-2.871a3.542 3.542 0 0 1 5.025.022Z" fill="currentColor"> </path> </svg> <div class="css-1btu0w3 evvkmar0" id="tasks"> </div> </a> </h2> <p class="leafygreen-ui-1kp3ins"> To learn how to keep a history of document and schema changes, see these pages: </p> <ul class="leafygreen-ui-rioki0"> <li class="leafygreen-ui-d7p7b6"> <p class="leafygreen-ui-1kp3ins"> <a class="leafygreen-ui-tqgtui" href="/docs/manual/data-modeling/design-patterns/data-versioning/document-versioning/#std-label-design-patterns-document-versioning"> Keep a History of Document Versions </a> </p> </li> <li class="leafygreen-ui-d7p7b6"> <p class="leafygreen-ui-1kp3ins"> <a class="leafygreen-ui-tqgtui" href="/docs/manual/data-modeling/design-patterns/data-versioning/schema-versioning/#std-label-design-patterns-schema-versioning"> Maintain Different Schema Versions </a> </p> </li> </ul> </section> <section> <h2 class="contains-headerlink leafygreen-ui-19f71ei" weight="medium"> Learn More <a class="headerlink leafygreen-ui-1kepx47" href="#learn-more" title="Permalink to this heading"> <svg aria-label="Link Icon" class="leafygreen-ui-a30zj9" fill="none" height="12" role="img" viewbox="0 0 16 16" width="12" xmlns="http://www.w3.org/2000/svg"> <path d="M6.039 9.953a3.596 3.596 0 0 1-.327-.38l1.45-1.445a1.553 1.553 0 0 0 2.496.423l2.885-2.87a1.57 1.57 0 0 0 .01-2.213 1.553 1.553 0 0 0-2.203-.01l-.379.377A.995.995 0 0 1 8.56 3.83a1.005 1.005 0 0 1 .006-1.418l.38-.377a3.542 3.542 0 0 1 5.024.023 3.58 3.58 0 0 1-.022 5.047l-2.884 2.871a3.542 3.542 0 0 1-5.025-.022Z" fill="currentColor"> </path> <path d="M9.961 6.047c.12.12.228.248.327.38l-1.45 1.445a1.553 1.553 0 0 0-2.496-.423l-2.885 2.87a1.57 1.57 0 0 0-.01 2.213 1.553 1.553 0 0 0 2.203.01l.379-.377a.995.995 0 0 1 1.411.006 1.005 1.005 0 0 1-.006 1.418l-.38.377a3.542 3.542 0 0 1-5.024-.023 3.58 3.58 0 0 1 .022-5.047l2.884-2.871a3.542 3.542 0 0 1 5.025.022Z" fill="currentColor"> </path> </svg> <div class="css-1btu0w3 evvkmar0" id="learn-more"> </div> </a> </h2> <ul class="leafygreen-ui-rioki0"> <li class="leafygreen-ui-d7p7b6"> <p class="leafygreen-ui-1kp3ins"> <a class="leafygreen-ui-tqgtui" href="/docs/manual/data-modeling/schema-design-process/#std-label-data-modeling-schema-design"> Schema Design Process </a> </p> </li> <li class="leafygreen-ui-d7p7b6"> <p class="leafygreen-ui-1kp3ins"> <a class="leafygreen-ui-tqgtui" href="/docs/manual/data-modeling/design-patterns/#std-label-schema-design-patterns"> Schema Design Patterns </a> </p> </li> <li class="leafygreen-ui-d7p7b6"> <p class="leafygreen-ui-1kp3ins"> <a class="leafygreen-ui-tqgtui" href="/docs/manual/data-modeling/data-consistency/#std-label-data-modeling-data-consistency"> Data Consistency </a> </p> </li> </ul> </section> </section>

For example, the following filter uses the $regex\nand $eq operators to return documents where a single array element\nends in Olsen and another element equals Mary-Kate Olsen or\na single element that satisfies both conditions:This query filter returns movies that include Mary-Kate Olsen in\ntheir cast, and movies that include both Mary-Kate Olsen and\nAshley Olsen in their cast.Query for an Array Element that Meets Multiple CriteriaUse $elemMatch operator to specify multiple criteria on the\nelements of an array such that at least one array element satisfies all\nthe specified criteria.The following example uses the $elemMatch and $ne\noperators to query for documents where the languages array contains\nat least one element that is both not null and does not equal English.Query for an Element by the Array Index PositionUsing dot notation, you can specify query conditions for an\nelement at a particular index or position of the array. The array uses\nzero-based indexing.When querying using dot notation, the field and nested field must be\ninside quotation marks.The following example uses the $ne operator to query\nfor all documents where the first element in the countries\narray is not equal to USA:Query an Array by Array LengthUse the $size operator to query for arrays by number of\nelements.

This initial creation and distribution of chunks allows for faster setup of zoned sharding. After the initial distribution, the balancer manages the chunk distribution going forward. </p> <p class="leafygreen-ui-1kp3ins"> See <a class="leafygreen-ui-tqgtui" href="/docs/manual/reference/method/sh.updateZoneKeyRange/#std-label-pre-define-zone-range-example"> Pre-Define Zones and Zone Ranges for an Empty or Non-Existing Collection </a> for an example. </p> </div> </div> <section> <h2 class="contains-headerlink leafygreen-ui-19f71ei" weight="medium"> Add Shards to a Zone <a class="headerlink leafygreen-ui-1kepx47" href="#add-shards-to-a-zone" title="Permalink to this heading"> <svg aria-label="Link Icon" class="leafygreen-ui-a30zj9" fill="none" height="12" role="img" viewbox="0 0 16 16" width="12" xmlns="http://www.w3.org/2000/svg"> <path d="M6.039 9.953a3.596 3.596 0 0 1-.327-.38l1.45-1.445a1.553 1.553 0 0 0 2.496.423l2.885-2.87a1.57 1.57 0 0 0 .01-2.213 1.553 1.553 0 0 0-2.203-.01l-.379.377A.995.995 0 0 1 8.56 3.83a1.005 1.005 0 0 1 .006-1.418l.38-.377a3.542 3.542 0 0 1 5.024.023 3.58 3.58 0 0 1-.022 5.047l-2.884 2.871a3.542 3.542 0 0 1-5.025-.022Z" fill="currentColor"> </path> <path d="M9.961 6.047c.12.12.228.248.327.38l-1.45 1.445a1.553 1.553 0 0 0-2.496-.423l-2.885 2.87a1.57 1.57 0 0 0-.01 2.213 1.553 1.553 0 0 0 2.203.01l.379-.377a.995.995 0 0 1 1.411.006 1.005 1.005 0 0 1-.006 1.418l-.38.377a3.542 3.542 0 0 1-5.024-.023 3.58 3.58 0 0 1 .022-5.047l2.884-2.871a3.542 3.542 0 0 1 5.025.022Z" fill="currentColor"> </path> </svg> <div class="css-1btu0w3 evvkmar0" id="add-shards-to-a-zone"> </div> </a> </h2> <p class="leafygreen-ui-1kp3ins"> Associate a Zone with a particular shard using the <a class="leafygreen-ui-tqgtui" href="/docs/manual/reference/method/sh.addShardToZone/#mongodb-method-sh.addShardToZone"> <code class="leafygreen-ui-1l06pbn"> sh.addShardToZone() </code> </a> method when connected to a <a class="leafygreen-ui-tqgtui" href="/docs/manual/reference/program/mongos/#mongodb-binary-bin.mongos"> <code class="leafygreen-ui-1l06pbn"> mongos </code> </a> instance.

You need to manually rebuild\nthe search index once the resharding operation completes.Block writes early to force resharding to completeYou can manually force the resharding operation to complete by\nissuing the commitReshardCollection command. This is\nuseful if the current time estimate to complete the resharding\noperation is an acceptable duration for your collection to block\nwrites. The commitReshardCollection command blocks\nwrites for the duration of the critical section and forces the\nresharding operation to complete. The command has the following\nsyntax:Abort resharding operationYou can abort the resharding operation during any stage of the\nresharding operation, even after running the\ncommitReshardCollection, until shards have fully caught\nup.For example, if remainingOperationTimeEstimatedSecs does not\ndecrease, you can abort the resharding operation with the\nabortReshardCollection command:After canceling the operation, you can retry the resharding\noperation during a time window with lower write volume. If this is\nnot possible, add more shards\nbefore retrying."}],"name":"Steps","image":"https://webimages.mongodb.com/_com_assets/cms/kuyj2focmkbxv7gh3-stacked_default_slate_blue.svg?auto=format%252Ccompress"} </script> <div class="css-4nyere

For example, the following filter uses the $regex\nand $eq operators to return documents where a single array element\nends in Olsen and another element equals Mary-Kate Olsen or\na single element that satisfies both conditions:This query filter returns movies that include Mary-Kate Olsen in\ntheir cast, and movies that include both Mary-Kate Olsen and\nAshley Olsen in their cast.Query for an Array Element that Meets Multiple CriteriaUse $elemMatch operator to specify multiple criteria on the\nelements of an array such that at least one array element satisfies all\nthe specified criteria.The following example uses the $elemMatch and $ne\noperators to query for documents where the languages array contains\nat least one element that is both not null and does not equal English.Query for an Element by the Array Index PositionUsing dot notation, you can specify query conditions for an\nelement at a particular index or position of the array. The array uses\nzero-based indexing.When querying using dot notation, the field and nested field must be\ninside quotation marks.The following example uses the $ne operator to query\nfor all documents where the first element in the countries\narray is not equal to USA:Query an Array by Array LengthUse the $size operator to query for arrays by number of\nelements. For example, the following selects documents where the array\ngenres has 3 elements.","name":"Specify a query filter document."}],"name":"Query an Array with MongoDB

This is\nuseful if the current time estimate to complete the resharding\noperation is an acceptable duration for your collection to block\nwrites. The commitReshardCollection command blocks\nwrites for the duration of the critical section and forces the\nresharding operation to complete. The command has the following\nsyntax:Abort resharding operationYou can abort the resharding operation during any stage of the\nresharding operation, even after running the\ncommitReshardCollection, until shards have fully caught\nup.For example, if remainingOperationTimeEstimatedSecs does not\ndecrease, you can abort the resharding operation with the\nabortReshardCollection command:After canceling the operation, you can retry the resharding\noperation during a time window with lower write volume. If this is\nnot possible, add more shards\nbefore retrying."}],"name":"Steps","image":"https://webimages.mongodb.com/_com_assets/cms/kuyj2focmkbxv7gh3-stacked_default_slate_blue.svg?auto=format%252Ccompress"} </script> <div class="css-4nyere
