    The BUILD INDEX statement enables you to build one or more GSI indexes that are marked for deferred building all at once.

    By default, CREATE INDEX statement starts building the created index. However for more efficient building of multiple indexes, CREATE INDEX command can mark indexes for deferred building using the defer_build:true option. BUILD INDEX is capable of building multiple indexes at once, and can utilize a single scan of documents in the bucket to feed many index build operations.

    BUILD INDEX is an asynchronous operation. BUILD INDEX creates a task to build the primary or secondary GSI indexes and returns as soon as the task is queued for execution. The full index creation operation happen in the background. Indexes of type GSI provide a status field and mark index status pending while the index build operation is in progress. This status field and other index metadata can be queried using system:indexes.

    When building an index which has automatic index replicas, all of the replicas are also built as part of the BUILD INDEX statement, without having to manually specify them.

    RBAC Privileges

    User executing the BUILD INDEX statement must have the Query Manage Index privilege granted on the keyspace/bucket. For more details about user roles, see Authorization.

    Known Issue

    If multiple index building operations are kicked off without waiting for all indexes to get to the online state, index building for some indexes might fail. In this case, system:indexes output might report an error similar to the following:

        "code": 5000,
        "msg": "BuildIndexes - cause: Build index fails.  Some index will be retried building in the background.  For more details, please check index status.\n",
        "query_from_user": "BUILD INDEX ON ..."

    To work around this issue, wait for index building to complete (that is, for all indexes to get to the online state), then issue the BUILD INDEX command again.


    BUILD INDEX ON named_keyspace_ref(index_name[,index_name]*) USING GSI;


    A unique name that identifies an index. A name must be specified for each index to be built.


    [ namespace-name :] keyspace-name


    keyspace-name is an identifier that refers to the bucket name. It specifies the bucket as the source for which the index needs to be created. You can add an optional namespace name to the keyspace name in this way:

    namespace-name : keyspace-name

    For example, main:customer indicates the customer keyspace in the main namespace. If the namespace name is omitted, the default namespace in the current session is used.


    The USING clause specifies the index type to use. The BUILD INDEX command can be used only with GSI indexes. Views do not support deferred building.


    The following example creates a set of primary and secondary indexes on the beer-sample bucket with the defer_build option. After the create index statement comes back, system:indexes is queried to for the status of the index.

    CREATE INDEX `beer-sample-type-index` ON `beer-sample`(type) USING GSI
       WITH {"defer_build":true};
    SELECT * FROM system:indexes WHERE name="beer-sample-type-index";

    With the defer_build option enabled, the output from system:indexes shows the beer-sample-type-index in the pending state ("state": "deferred"). BUILD INDEX can be used to kick off the deferred build on the index on type attribute.

    BUILD INDEX ON `beer-sample`(`beer-sample-type-index`) USING GSI;
    SELECT * FROM system:indexes WHERE name="beer-sample-type-index";
