Google Cloud Dataproc Metastore V1beta Client - Class DataprocMetastoreFederationClient (0.10.2)

Reference documentation and code samples for the Google Cloud Dataproc Metastore V1beta Client class DataprocMetastoreFederationClient.

Service Description: Configures and manages metastore federation services.

Dataproc Metastore Federation Service allows federating a collection of backend metastores like BigQuery, Dataplex Lakes, and other Dataproc Metastores. The Federation Service exposes a gRPC URL through which metadata from the backend metastores are served at query time.

The Dataproc Metastore Federation API defines the following resource model:

  • The service works with a collection of Google Cloud projects.
  • Each project has a collection of available locations.
  • Each location has a collection of federations.
  • Dataproc Metastore Federations are resources with names of the form: projects/{project_number}/locations/{location_id}/federations/{federation_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:

$dataprocMetastoreFederationClient = new DataprocMetastoreFederationClient();
try {
    $formattedParent = $dataprocMetastoreFederationClient->locationName('[PROJECT]', '[LOCATION]');
    $federationId = 'federation_id';
    $federation = new Federation();
    $operationResponse = $dataprocMetastoreFederationClient->createFederation($formattedParent, $federationId, $federation);
    $operationResponse->pollUntilComplete();
    if ($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 = $dataprocMetastoreFederationClient->createFederation($formattedParent, $federationId, $federation);
    $operationName = $operationResponse->getName();
    // ... do other work
    $newOperationResponse = $dataprocMetastoreFederationClient->resumeOperation($operationName, 'createFederation');
    while (!$newOperationResponse->isDone()) {
        // ... do other work
        $newOperationResponse->reload();
    }
    if ($newOperationResponse->operationSucceeded()) {
        $result = $newOperationResponse->getResult();
    // doSomethingWith($result)
    } else {
        $error = $newOperationResponse->getError();
        // handleError($error)
    }
} finally {
    $dataprocMetastoreFederationClient->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.

Namespace

Google \ Cloud \ Metastore \ V1beta

Methods

__construct

Constructor.

Parameters
NameDescription
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.

createFederation

Creates a metastore federation in a project and location.

Parameters
NameDescription
parent string

Required. The relative resource name of the location in which to create a federation service, in the following form:

projects/{project_number}/locations/{location_id}.

federationId string

Required. The ID of the metastore federation, which is used as the final component of the metastore federation's name.

This value must be between 2 and 63 characters long inclusive, begin with a letter, end with a letter or number, and consist of alpha-numeric ASCII characters or hyphens.

federation Google\Cloud\Metastore\V1beta\Federation

Required. The Metastore Federation to create. The name field is ignored. The ID of the created metastore federation must be provided in the request's federation_id field.

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

setIamPolicy

Sets the access control policy on the specified resource. Replaces any existing policy.

Can return NOT_FOUND, INVALID_ARGUMENT, and PERMISSION_DENIED errors.

Parameters
NameDescription
resource string

REQUIRED: The resource for which the policy is being specified. See the operation documentation for the appropriate value for this field.

policy Google\Cloud\Iam\V1\Policy

REQUIRED: The complete policy to be applied to the resource. The size of the policy is limited to a few 10s of KB. An empty policy is a valid policy but certain Cloud Platform services (such as Projects) might reject them.

optionalArgs array

Optional.

↳ updateMask FieldMask

OPTIONAL: A FieldMask specifying which fields of the policy to modify. Only the fields in the mask will be modified. If no mask is provided, the following default mask is used: paths: "bindings, etag"

↳ retrySettings RetrySettings|array

Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage.

Returns
TypeDescription
Google\Cloud\Iam\V1\Policy
Example
use Google\ApiCore\ApiException;
use Google\Cloud\Iam\V1\Policy;
use Google\Cloud\Metastore\V1beta\DataprocMetastoreFederationClient;

testIamPermissions

Returns permissions that a caller has on the specified resource. If the resource does not exist, this will return an empty set of permissions, not a NOT_FOUND error.

Note: This operation is designed to be used for building permission-aware UIs and command-line tools, not for authorization checking. This operation may "fail open" without warning.

Parameters
NameDescription
resource string

REQUIRED: The resource for which the policy detail is being requested. See the operation documentation for the appropriate value for this field.

permissions string[]

The set of permissions to check for the resource. Permissions with wildcards (such as '' or 'storage.') are not allowed. For more information see IAM Overview.

optionalArgs array

Optional.
