default mTLS endpoint if client certificate is present; this is
the default value).

is "true", then the ``client_cert_source`` property can be used

not provided, the default SSL client certificate will be used if

Args:
request (Union[google.maps.routeoptimization_v1.types.BatchOptimizeToursRequest, dict]):
The request object. Request to batch optimize tours as an asynchronous
operation. Each input file should contain one
``OptimizeToursRequest``, and each output file will
contain one ``OptimizeToursResponse``. The request
contains information to read/write and parse the files.
All the input and output files should be under the same
project.
retry (google.api_core.retry.Retry): Designation of what errors, if any,
should be retried.
timeout (float): The timeout for this request.
metadata (Sequence[Tuple[str, str]]): Strings which should be
sent along with the request as metadata.
Returns:
google.api_core.operation.Operation:
An object representing a long-running operation.
The result type for the operation will be :class:`google.maps.routeoptimization_v1.types.BatchOptimizeToursResponse` Response to a BatchOptimizeToursRequest. This is returned in
the Long Running Operation after the operation is
complete.
