            # REST client for the DataprocMetastore service.
            #
            # Configures and manages metastore services.
            # Metastore services are fully managed, highly available, autoscaled,
            # autohealing, OSS-native deployments of technical metadata management
            # software. Each metastore service exposes a network endpoint through which
            # metadata queries are served. Metadata queries can originate from a variety
            # of sources, including Apache Hive, Apache Presto, and Apache Spark.
            #
            # The Dataproc Metastore API defines the following resource model:
            #
            # * The service works with a collection of Google Cloud projects, named:
            # `/projects/*`
            # * Each project has a collection of available locations, named: `/locations/*`
            #   (a location must refer to a Google Cloud `region`)
            # * Each location has a collection of services, named: `/services/*`
            # * Dataproc Metastore services are resources with names of the form:
            #
            #   `/projects/{project_number}/locations/{location_id}/services/{service_id}`.
