// 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}`.
