            # * The service works with a collection of cloud projects, named: `/projects/*`
            # * Each project has a collection of available locations, named: `/locations/*`
            # * Each location has a collection of Redis clusters, named: `/clusters/*`
            # * As such, Redis clusters are resources of the form:
            #   `/projects/{project_id}/locations/{location_id}/clusters/{instance_id}`
            #
            # Note that location_id must be a GCP `region`; for example:
