        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``.

        On successful completion, ``Operation.response`` will be ``Empty``.

        Example:
            >>> from google.cloud import dataproc_v1beta2
            >>>
            >>> client = dataproc_v1beta2.WorkflowTemplateServiceClient()
            >>>
            >>> parent = client.region_path('[PROJECT]', '[REGION]')
            >>>
            >>> # TODO: Initialize `template`:
            >>> template = {}
            >>>
            >>> response = client.instantiate_inline_workflow_template(parent, template)
            >>>
            >>> def callback(operation_future):
            ...     # Handle result.
            ...     result = operation_future.result()
            >>>
            >>> response.add_done_callback(callback)
            >>>
            >>> # Handle metadata.
            >>> metadata = response.metadata()

        Args:
            parent (str): Required. The "resource name" of the workflow template region, as
                described in https://cloud.google.com/apis/design/resource\_names of the
                form ``projects/{project_id}/regions/{region}``
            template (Union[dict, ~google.cloud.dataproc_v1beta2.types.WorkflowTemplate]): Required. The workflow template to instantiate.

                If a dict is provided, it must be of the same form as the protobuf
                message :class:`~google.cloud.dataproc_v1beta2.types.WorkflowTemplate`
            instance_id (str): Deprecated. Please use ``request_id`` field instead.
            request_id (str): 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 <https://en.wikipedia.org/wiki/Universally_unique_identifier>`__.

                The tag must contain only letters (a-z, A-Z), numbers (0-9), underscores
                (\_), and hyphens (-). The maximum length is 40 characters.
            retry (Optional[google.api_core.retry.Retry]):  A retry object used
                to retry requests. If ``None`` is specified, requests will not
                be retried.
            timeout (Optional[float]): The amount of time, in seconds, to wait
                for the request to complete. Note that if ``retry`` is
                specified, the timeout applies to each individual attempt.
            metadata (Optional[Sequence[Tuple[str, str]]]): Additional metadata
                that is provided to the method.

        Returns:
            A :class:`~google.cloud.dataproc_v1beta2.types._OperationFuture` instance.

        Raises:
            google.api_core.exceptions.GoogleAPICallError: If the request
                    failed for any reason.
            google.api_core.exceptions.RetryError: If the request failed due
                    to a retryable error and retry attempts failed.
            ValueError: If the parameters are invalid.
