Google Cloud Dataproc V1 Client - Class WorkflowTemplateServiceClient (3.6.1)

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

Service Description: The API interface for managing Workflow Templates in the Dataproc API.

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:

$workflowTemplateServiceClient = new WorkflowTemplateServiceClient();
try {
    $formattedParent = $workflowTemplateServiceClient->regionName('[PROJECT]', '[REGION]');
    $template = new WorkflowTemplate();
    $response = $workflowTemplateServiceClient->createWorkflowTemplate($formattedParent, $template);
} finally {
    $workflowTemplateServiceClient->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.

instantiateInlineWorkflowTemplate

Instantiates a template and begins execution.

This method is equivalent to executing the sequence CreateWorkflowTemplate, InstantiateWorkflowTemplate, DeleteWorkflowTemplate.

The returned Operation can be used to track execution of workflow by polling operations.get. The Operation will complete when entire workflow is finished.

The running workflow can be aborted via operations.cancel. This will cause any inflight jobs to be cancelled and workflow-owned clusters to be deleted.

The Operation.metadata will be WorkflowMetadata. Also see Using WorkflowMetadata.

On successful completion, Operation.response will be Empty.

Parameters
Name	Description
`parent`	`string` Required. The resource name of the region or location, as described in https://cloud.google.com/apis/design/resource_names. For `projects.regions.workflowTemplates,instantiateinline`, the resource name of the region has the following format: `projects/{project_id}/regions/{region}` For `projects.locations.workflowTemplates.instantiateinline`, the resource name of the location has the following format: `projects/{project_id}/locations/{location}`
`template`	`Google\Cloud\Dataproc\V1\WorkflowTemplate` Required. The workflow template to instantiate.
`optionalArgs`	`array` Optional.
`↳ requestId`	`string` Optional. A tag that prevents multiple concurrent workflow instances with the same tag from running. This mitigates risk of concurrent instances started due to retries. It is recommended to always set this value to a UUID. The tag 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.

`optionalArgs`	`array` Optional.
`↳ version`	`int` Optional. The version of workflow template to instantiate. If specified, the workflow will be instantiated only if the current version of the workflow template has the supplied version. This option cannot be used to instantiate a previous version of workflow template.
`↳ requestId`	`string` Optional. A tag that prevents multiple concurrent workflow instances with the same tag from running. This mitigates risk of concurrent instances started due to retries. It is recommended to always set this value to a UUID. The tag must contain only letters (a-z, A-Z), numbers (0-9), underscores (_), and hyphens (-). The maximum length is 40 characters.
`↳ parameters`	`array` Optional. Map from parameter names to values that should be used for those parameters. Values may not exceed 1000 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.
