The interfaces provided are listed below, along with usage samples.

DataprocMetastoreClient

Service Description: 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}.

Sample for DataprocMetastoreClient:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (DataprocMetastoreClient dataprocMetastoreClient = DataprocMetastoreClient.create()) {
   ServiceName name = ServiceName.of("[PROJECT]", "[LOCATION]", "[SERVICE]");
   Service response = dataprocMetastoreClient.getService(name);
 }

DataprocMetastoreFederationClient

Service Description: Configures and manages metastore federation services. Dataproc Metastore Federation Service allows federating a collection of backend metastores like BigQuery, Dataplex Lakes, and other Dataproc Metastores. The Federation Service exposes a gRPC URL through which metadata from the backend metastores are served at query time.

The Dataproc Metastore Federation API defines the following resource model:

  • The service works with a collection of Google Cloud projects.
  • Each project has a collection of available locations.
  • Each location has a collection of federations.
  • Dataproc Metastore Federations are resources with names of the form: projects/{project_number}/locations/{location_id}/federations/{federation_id}.

 try (DataprocMetastoreFederationClient dataprocMetastoreFederationClient =
     DataprocMetastoreFederationClient.create()) {
   FederationName name = FederationName.of("[PROJECT]", "[LOCATION]", "[FEDERATION]");
   Federation response = dataprocMetastoreFederationClient.getFederation(name);
