Class WorkflowTemplateServiceClient (4.33.0)

GitHub RepositoryProduct ReferenceREST DocumentationRPC Documentation

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:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 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().

Methods
MethodDescriptionMethod Variants

CreateWorkflowTemplate

Creates new workflow template.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • createWorkflowTemplate(CreateWorkflowTemplateRequest request)

"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

  • createWorkflowTemplate(LocationName parent, WorkflowTemplate template)

  • createWorkflowTemplate(RegionName parent, WorkflowTemplate template)

  • createWorkflowTemplate(String parent, WorkflowTemplate template)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • createWorkflowTemplateCallable()

GetWorkflowTemplate

Retrieves the latest workflow template.

Can retrieve previously instantiated template by specifying optional version parameter.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • getWorkflowTemplate(GetWorkflowTemplateRequest request)

"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

  • getWorkflowTemplate(WorkflowTemplateName name)

  • getWorkflowTemplate(String name)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • getWorkflowTemplateCallable()

InstantiateWorkflowTemplate

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.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • instantiateWorkflowTemplateAsync(InstantiateWorkflowTemplateRequest request)

Methods that return long-running operations have "Async" method variants that return OperationFuture, which is used to track polling of the service.

  • instantiateWorkflowTemplateAsync(WorkflowTemplateName name)

  • instantiateWorkflowTemplateAsync(String name)

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

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

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • instantiateWorkflowTemplateOperationCallable()

  • instantiateWorkflowTemplateCallable()

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.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • instantiateInlineWorkflowTemplateAsync(InstantiateInlineWorkflowTemplateRequest request)

Methods that return long-running operations have "Async" method variants that return OperationFuture, which is used to track polling of the service.

  • instantiateInlineWorkflowTemplateAsync(LocationName parent, WorkflowTemplate template)

  • instantiateInlineWorkflowTemplateAsync(String parent, WorkflowTemplate template)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • instantiateInlineWorkflowTemplateOperationCallable()

  • instantiateInlineWorkflowTemplateCallable()

UpdateWorkflowTemplate

Updates (replaces) workflow template. The updated template must contain version that matches the current server version.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • updateWorkflowTemplate(UpdateWorkflowTemplateRequest request)

"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

  • updateWorkflowTemplate(WorkflowTemplate template)

Callable method variants take no parameters and return 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:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 WorkflowTemplateServiceSettings workflowTemplateServiceSettings =
     WorkflowTemplateServiceSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 WorkflowTemplateServiceClient workflowTemplateServiceClient =
     WorkflowTemplateServiceClient.create(workflowTemplateServiceSettings);

To customize the endpoint:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 WorkflowTemplateServiceSettings workflowTemplateServiceSettings =
     WorkflowTemplateServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
 WorkflowTemplateServiceClient workflowTemplateServiceClient =
     WorkflowTemplateServiceClient.create(workflowTemplateServiceSettings);

To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over the wire:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 WorkflowTemplateServiceSettings workflowTemplateServiceSettings =
     WorkflowTemplateServiceSettings.newHttpJsonBuilder().build();
 WorkflowTemplateServiceClient workflowTemplateServiceClient =
     WorkflowTemplateServiceClient.create(workflowTemplateServiceSettings);
