REVOKE

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 buckets/resources in the cluster.

For example: ClusterAdmin or BucketAdmin

parameterized by a bucket

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

For example: BucketReader 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.
