Google Cloud Dataproc V1 Client - Class BatchControllerClient (3.8.1)

Reference documentation and code samples for the Google Cloud Dataproc V1 Client class BatchControllerClient.

Service Description: The BatchController provides methods to manage batch workloads.

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:

$batchControllerClient = new BatchControllerClient();
try {
    $formattedParent = $batchControllerClient->locationName('[PROJECT]', '[LOCATION]');
    $batch = new Batch();
    $operationResponse = $batchControllerClient->createBatch($formattedParent, $batch);
    $operationResponse->pollUntilComplete();
    if ($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 = $batchControllerClient->createBatch($formattedParent, $batch);
    $operationName = $operationResponse->getName();
    // ... do other work
    $newOperationResponse = $batchControllerClient->resumeOperation($operationName, 'createBatch');
    while (!$newOperationResponse->isDone()) {
        // ... do other work
        $newOperationResponse->reload();
    }
    if ($newOperationResponse->operationSucceeded()) {
        $result = $newOperationResponse->getResult();
        // doSomethingWith($result)
    } else {
        $error = $newOperationResponse->getError();
        // handleError($error)
    }
} finally {
    $batchControllerClient->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.

This service has a new (beta) implementation. See Google\Cloud\Dataproc\V1\Client\BatchControllerClient to use the new surface.

Namespace

Google \ Cloud \ Dataproc \ V1

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.

createBatch

Creates a batch workload that executes asynchronously.

Parameters
NameDescription
parent string

Required. The parent resource where this batch will be created.

batch Google\Cloud\Dataproc\V1\Batch

Required. The batch to create.

optionalArgs array

Optional.

↳ batchId string

Optional. The ID to use for the batch, which will become the final component of the batch's resource name. This value must be 4-63 characters. Valid characters are /[a-z][0-9]-/.

↳ requestId string

Optional. A unique ID used to identify the request. If the service receives two CreateBatchRequests with the same request_id, the second request is ignored and the Operation that corresponds to the first Batch created and stored in the backend is returned. Recommendation: Set this value to a UUID. The value must contain only letters (a-z, A-Z), numbers (0-9), underscores (_), and hyphens (-). The maximum length is 40 characters.

↳ 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.

listBatches

Lists batch workloads.

Parameters
NameDescription
parent string

Required. The parent, which owns this collection of batches.

optionalArgs array

Optional.

↳ pageSize int

The maximum number of resources contained in the underlying API response. The API may return fewer values in a page, even if there are additional values to be retrieved.

↳ pageToken string

A page token is used to specify a page of values to be returned. If no page token is specified (the default), the first page of values will be returned. Any page token used here must have been generated by a previous call to the API.

↳ filter string

Optional. A filter for the batches to return in the response. A filter is a logical expression constraining the values of various fields in each batch resource. Filters are case sensitive, and may contain multiple clauses combined with logical operators (AND/OR). Supported fields are batch_id, batch_uuid, state, and create_time. e.g. state = RUNNING and create_time < "2023-01-01T00:00:00Z" filters for batches in state RUNNING that were created before 2023-01-01 See https://google.aip.dev/assets/misc/ebnf-filtering.txt for a detailed description of the filter syntax and a list of supported comparisons.

↳ orderBy string

Optional. Field(s) on which to sort the list of batches. Currently the only supported sort orders are unspecified (empty) and create_time desc to sort by most recently created batches first. See https://google.aip.dev/132#ordering for more details.
