public static interface DataprocMetastoreFederationGrpc.AsyncService
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}
.
