Google Cloud Dataproc Metastore V1alpha Client - Class DataprocMetastoreClient (1.0.1)

Reference documentation and code samples for the Google Cloud Dataproc Metastore V1alpha Client class DataprocMetastoreClient.

Service Description: 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}.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods.

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parseName method to extract the individual identifiers contained within formatted names that are returned by the API.

Namespace

Google \ Cloud \ Metastore \ V1alpha \ Client

Methods

__construct

Constructor.

Parameters
Name Description
options array

Optional. Options for configuring the service API wrapper.
↳ apiEndpoint string

The address of the API remote host. May optionally include the port, formatted as "
↳ credentials string|array|FetchAuthTokenInterface|CredentialsWrapper

The credentials to be used by the client to authorize API calls. This option accepts either a path to a credentials file, or a decoded credentials file as a PHP array. Advanced usage: In addition, this option can also accept a pre-constructed Google\Auth\FetchAuthTokenInterface object or Google\ApiCore\CredentialsWrapper object. Note that when one of these objects are provided, any settings in $credentialsConfig will be ignored.
↳ credentialsConfig array

Options used to configure credentials, including auth token caching, for the client. For a full list of supporting configuration options, see Google\ApiCore\CredentialsWrapper::build() .
↳ disableRetries bool

Determines whether or not retries defined by the client configuration should be disabled. Defaults to false.
↳ clientConfig string|array

Client method configuration, including retry settings. This option can be either a path to a JSON file, or a PHP array containing the decoded JSON data. By default this settings points to the default client config file, which is provided in the resources folder.
↳ transport string|TransportInterface

The transport used for executing network requests. May be either the string rest or grpc. Defaults to grpc if gRPC support is detected on the system. Advanced usage: Additionally, it is possible to pass in an already instantiated Google\ApiCore\Transport\TransportInterface object. Note that when this object is provided, any settings in $transportConfig, and any $apiEndpoint setting, will be ignored.
↳ transportConfig array

Configuration options that will be used to construct the transport. Options for each supported transport type should be passed in a key for that transport. For example: $transportConfig = [ 'grpc' => [...], 'rest' => [...], ]; See the Google\ApiCore\Transport\GrpcTransport::build() and Google\ApiCore\Transport\RestTransport::build() methods for the supported options.
↳ clientCertSource callable

A callable which returns the client cert as a string. This can be used to provide a certificate and private key to the transport layer for mTLS.

alterMetadataResourceLocation

Alter metadata resource location. The metadata resource can be a database, table, or partition. This functionality only updates the parent directory for the respective metadata resource and does not transfer any existing data to the new location.

The async variant is DataprocMetastoreClient::alterMetadataResourceLocationAsync() .
