            # Memorystore Memcached (also called Memcached below) instances:
            # * 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 Memcached instances, named:
            # `/instances/*`
            # * As such, Memcached instances are resources of the form:
            #   `/projects/{project_id}/locations/{location_id}/instances/{instance_id}`
            #
            # Note that location_id must be a GCP `region`; for example:
