Federation(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Represents a federation of multiple backend metastores.

Attributes
Name	Description
name	str Immutable. The relative resource name of the federation, of the form: projects/{project_number}/locations/{location_id}/federations/{federation_id}`.
create_time	google.protobuf.timestamp_pb2.Timestamp Output only. The time when the metastore federation was created.
update_time	google.protobuf.timestamp_pb2.Timestamp Output only. The time when the metastore federation was last updated.
labels	MutableMapping[str, str] User-defined labels for the metastore federation.
version	str Immutable. The Apache Hive metastore version of the federation. All backend metastore versions must be compatible with the federation version.
backend_metastores	MutableMapping[int, google.cloud.metastore_v1alpha.types.BackendMetastore] A map from BackendMetastore rank to BackendMetastore\ s from which the federation service serves metadata at query time. The map key represents the order in which BackendMetastore\ s should be evaluated to resolve database names at query time and should be greater than or equal to zero. A BackendMetastore with a lower number will be evaluated before a BackendMetastore with a higher number.
endpoint_uri	str Output only. The federation endpoint.
state	google.cloud.metastore_v1alpha.types.Federation.State Output only. The current state of the federation.
state_message	str Output only. Additional information about the current state of the metastore federation, if available.
uid	str Output only. The globally unique resource identifier of the metastore federation.
