public static interface DataprocMetastoreGrpc.AsyncService

Configures and manages metastore services. Metastore services are fully managed, highly available, autoscaled, autohealing, OSS-native deployments of technical metadata management software. Each metastore service exposes a network endpoint through which metadata queries are served. Metadata queries can originate from a variety of sources, including Apache Hive, Apache Presto, and Apache Spark. The Dataproc Metastore API defines the following resource model:

• The service works with a collection of Google Cloud projects, named: /projects/*
• Each project has a collection of available locations, named: /locations/* (a location must refer to a Google Cloud region)
• Each location has a collection of services, named: /services/*
• Dataproc Metastore services are resources with names of the form: /projects/{project_number}/locations/{location_id}/services/{service_id}.

Methods

alterMetadataResourceLocation(AlterMetadataResourceLocationRequest request, StreamObserver<Operation> responseObserver)

public default void alterMetadataResourceLocation(AlterMetadataResourceLocationRequest request, StreamObserver<Operation> responseObserver)

responseObserver	io.grpc.stub.StreamObserver<Operation>

createBackup(CreateBackupRequest request, StreamObserver<Operation> responseObserver)

public default void createBackup(CreateBackupRequest request, StreamObserver<Operation> responseObserver)

Creates a new backup in a given project and location.

Parameters
Name	Description
request	CreateBackupRequest
responseObserver	io.grpc.stub.StreamObserver<Operation>

createMetadataImport(CreateMetadataImportRequest request, StreamObserver<Operation> responseObserver)

public default void createMetadataImport(CreateMetadataImportRequest request, StreamObserver<Operation> responseObserver)
