Reference documentation and code samples for the Dataproc Metastore v1alpha API class 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}.
public static void BindService(ServiceBinderBase serviceBinder, DataprocMetastoreFederation.DataprocMetastoreFederationBase serviceImpl)
Register service method with a service binder with or without implementation. Useful when customizing the service binding logic.
Note: this method is part of an experimental API that can change or be removed without any prior notice.
