          # 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}`.
