public class WorkflowTemplateServiceClient implements BackgroundResource

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:

 try (WorkflowTemplateServiceClient workflowTemplateServiceClient =
     WorkflowTemplateServiceClient.create()) {
   LocationName parent = LocationName.of("[PROJECT]", "[LOCATION]");
   WorkflowTemplate template = WorkflowTemplate.newBuilder().build();
   WorkflowTemplate response =
       workflowTemplateServiceClient.createWorkflowTemplate(parent, template);
 }
 

Note: close() needs to be called on the WorkflowTemplateServiceClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

The surface of this class includes several types of Java methods for each of the API's methods:

1. A "flattened" method. With this type of method, the fields of the request type have been converted into function parameters. It may be the case that not all fields are available as parameters, and not every API method will have a flattened method entry point.
2. A "request object" method. This type of method only takes one parameter, a request object, which must be constructed before the call. Not every API method will have a request object method.
3. A "callable" method. This type of method takes no parameters and returns an immutable API callable object, which can be used to initiate calls to the service.

See the individual methods for example code.

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 parse method to extract the individual identifiers contained within names that are returned.

This class can be customized by passing in a custom instance of WorkflowTemplateServiceSettings to create(). For example:

To customize credentials:

 WorkflowTemplateServiceSettings workflowTemplateServiceSettings =
     WorkflowTemplateServiceSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 WorkflowTemplateServiceClient workflowTemplateServiceClient =
     WorkflowTemplateServiceClient.create(workflowTemplateServiceSettings);
 

To customize the endpoint:

 WorkflowTemplateServiceSettings workflowTemplateServiceSettings =
     WorkflowTemplateServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
 WorkflowTemplateServiceClient workflowTemplateServiceClient =
     WorkflowTemplateServiceClient.create(workflowTemplateServiceSettings);

instantiateInlineWorkflowTemplateAsync(InstantiateInlineWorkflowTemplateRequest request)

public final OperationFuture<Empty,WorkflowMetadata> instantiateInlineWorkflowTemplateAsync(InstantiateInlineWorkflowTemplateRequest request)

Instantiates a template and begins execution.

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

Parameter

Name

Description

name

WorkflowTemplateName Required. The resource name of the workflow template, as described in https://cloud.google.com/apis/design/resource_names. For projects.regions.workflowTemplates.instantiate, the resource name of the template has the following format: projects/{project_id}/regions/{region}/workflowTemplates/{template_id} For projects.locations.workflowTemplates.instantiate, the resource name of the template has the following format: projects/{project_id}/locations/{location}/workflowTemplates/{template_id}

Returns

Type	Description
OperationFuture<Empty,WorkflowMetadata>

instantiateWorkflowTemplateAsync(WorkflowTemplateName name, Map<String,String> parameters)

public final OperationFuture<Empty,WorkflowMetadata> instantiateWorkflowTemplateAsync(WorkflowTemplateName name, Map<String,String> parameters)

Instantiates a template and begins execution.

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.

Sample code:

 try (WorkflowTemplateServiceClient workflowTemplateServiceClient =
     WorkflowTemplateServiceClient.create()) {
   WorkflowTemplateName name =
       WorkflowTemplateName.ofProjectRegionWorkflowTemplateName(
           "[PROJECT]", "[REGION]", "[WORKFLOW_TEMPLATE]");
