Class DataprocMetastoreFederationGrpc.DataprocMetastoreFederationStub (2.21.0)

public static final class DataprocMetastoreFederationGrpc.DataprocMetastoreFederationStub extends AbstractAsyncStub<DataprocMetastoreFederationGrpc.DataprocMetastoreFederationStub>

A stub to allow clients to do asynchronous rpc calls to service DataprocMetastoreFederation.

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}.
