async instantiate_workflow_template(template_name, project_id, region, version=None, request_id=None, parameters=None, retry=DEFAULT, timeout=None, metadata=())[source]¶

Parameters

template_name (str) – Name of template to instantiate.
project_id (str) – Required. The ID of the Google Cloud project the cluster belongs to.
region (str) – Required. The Cloud Dataproc region in which to handle the request.
