public sealed class DataprocMetastoreClientImpl : DataprocMetastoreClient

Reference documentation and code samples for the Dataproc Metastore v1 API class DataprocMetastoreClientImpl.

DataprocMetastore client wrapper implementation, for convenient use.

Inheritance

object > DataprocMetastoreClient > DataprocMetastoreClientImpl

Namespace

Google.Cloud.Metastore.V1

Assembly

Google.Cloud.Metastore.V1.dll

Remarks

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}.

Constructors

DataprocMetastoreClientImpl(DataprocMetastoreClient, DataprocMetastoreSettings, ILogger)

public DataprocMetastoreClientImpl(DataprocMetastore.DataprocMetastoreClient grpcClient, DataprocMetastoreSettings settings, ILogger logger)

Constructs a client wrapper for the DataprocMetastore service, with the specified gRPC client and settings.
