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

    Roles can be of the following two types:

    simple

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

    For example: ClusterAdmin or BucketAdmin

    parameterized by a keyspace

    Roles which are defined for the scope of the specified keyspace only. The keyspace name is specified after ON.

    For example: DataReader ON `travel-sample`
    or Query_Select ON `travel-sample`

    Only Full Administrators can run the REVOKE statement. For more details about user roles, see Authorization.

    Syntax
