    The REVOKE statement allows revoking of any RBAC roles from specific users or groups.

    Roles can be of the following two types:

    simple

    Roles which apply generically to all keyspaces/resources in the cluster.

    For example: cluster_admin or bucket_admin

    parameterized by a keyspace

    Roles which are defined for the context of the specified keyspace only. Specify the keyspace name after the keyword ON.

    For example: data_reader ON `travel-sample`
    or query_select ON `travel-sample`.`inventory`.`airline`

    To run the REVOKE statement, you must be an Organization Owner or Project Owner.
