instantiate_inline_workflow_template
instantiate_inline_workflow_template(parent, template, instance_id=None, request_id=None, retry=<object object>, timeout=<object object>, metadata=None)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 <https://cloud.google.com/dataproc/docs/reference/rpc/google.cloud.dataproc.v1#workflowmetadata>.
Also see Using
WorkflowMetadata <https://cloud.google.com/dataproc/docs/concepts/workflows/debugging#using_workflowmetadata>.
On successful completion, Operation.response will be Empty.

| instance_id |
