Google Cloud Dataproc Metastore V1alpha Client - Class DataprocMetastoreClient (0.4.1)

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. Sample code to get started:

$dataprocMetastoreClient = new DataprocMetastoreClient();
try {
    $formattedParent = $dataprocMetastoreClient->serviceName('[PROJECT]', '[LOCATION]', '[SERVICE]');
    $backupId = 'backup_id';
    $backup = new Backup();
    $operationResponse = $dataprocMetastoreClient->createBackup($formattedParent, $backupId, $backup);
    $operationResponse->pollUntilComplete();
    if ($operationResponse->operationSucceeded()) {
        $result = $operationResponse->getResult();
    // doSomethingWith($result)
    } else {
        $error = $operationResponse->getError();
        // handleError($error)
    }
    // Alternatively:
    // start the operation, keep the operation name, and resume later
    $operationResponse = $dataprocMetastoreClient->createBackup($formattedParent, $backupId, $backup);
    $operationName = $operationResponse->getName();
    // ... do other work
    $newOperationResponse = $dataprocMetastoreClient->resumeOperation($operationName, 'createBackup');
    while (!$newOperationResponse->isDone()) {
        // ... do other work
        $newOperationResponse->reload();
    }
    if ($newOperationResponse->operationSucceeded()) {
        $result = $newOperationResponse->getResult();
    // doSomethingWith($result)
    } else {
        $error = $newOperationResponse->getError();
        // handleError($error)
    }
} finally {
    $dataprocMetastoreClient->close();
}

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.

parseName

Parses a formatted name string and returns an associative array of the components in the name.

The following name formats are supported: Template: Pattern

backup: projects/{project}/locations/{location}/services/{service}/backups/{backup}
location: projects/{project}/locations/{location}
metadataImport: projects/{project}/locations/{location}/services/{service}/metadataImports/{metadata_import}
network: projects/{project}/global/networks/{network}
service: projects/{project}/locations/{location}/services/{service}

The optional $template argument can be supplied to specify a particular pattern, and must match one of the templates listed above. If no $template argument is provided, or if the $template argument does not match one of the templates listed, then parseName will check each of the supported templates, and return the first match.

`↳ 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 {@see} object or {@see} 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 {@see} .
`↳ disableRetries`	`bool` Determines whether or not retries defined by the client configuration should be disabled. Defaults to `false`.

Advanced usage: Additionally, it is possible to pass in an already instantiated {@see} 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 {@see} and {@see} 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.

Exports metadata from a service.

Parameters
Name	Description
`service`	`string` Required. The relative resource name of the metastore service to run export, in the following form: `projects/{project_id}/locations/{location_id}/services/{service_id}`.
`optionalArgs`	`array` Optional.

Only the description field of MetadataImport is supported to be updated.

Parameters
Name	Description
`updateMask`	`Google\Protobuf\FieldMask` Required. A field mask used to specify the fields to be overwritten in the metadata import resource by the update. Fields specified in the `update_mask` are relative to the resource (not to the full request). A field is overwritten if it is in the mask.
`metadataImport`	`Google\Cloud\Metastore\V1alpha\MetadataImport` Required. The metadata import to update. The server only merges fields in the import if they are specified in `update_mask`. The metadata import's `name` field is used to identify the metastore import to be updated.
`optionalArgs`	`array` Optional.
`↳ requestId`	`string` Optional. A request ID. Specify a unique request ID to allow the server to ignore the request if it has completed. The server will ignore subsequent requests that provide a duplicate request ID for at least 60 minutes after the first request. For example, if an initial request times out, followed by another request with the same request ID, the server ignores the second request to prevent the creation of duplicate commitments. The request ID must be a valid UUID A zero UUID (00000000-0000-0000-0000-000000000000) is not supported.
`↳ retrySettings`	`RetrySettings\|array` Retry settings to use for this call. Can be a {@see} object, or an associative array of retry settings parameters. See the documentation on {@see} for example usage.

updateService

Updates the parameters of a single service.

Parameters
Name	Description
