``transport`` was not explicitly provided, the endpoint is
determined by the GOOGLE_API_USE_MTLS_ENDPOINT environment

"always" (always use the default mTLS endpoint), "never" (always
use the default regular endpoint) and "auto" (auto-switch to the
default mTLS endpoint if client certificate is present; this is
the default value).
2. If the GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable
is "true", then the ``client_cert_source`` property can be used
to provide a client certificate for mTLS transport. If
not provided, the default SSL client certificate will be used if
present. If GOOGLE_API_USE_CLIENT_CERTIFICATE is "false" or not
set, no client certificate will be used.

The request object. Request for

instance (str):
Required. Memcache instance resource name using the
form:
``projects/{project_id}/locations/{location_id}/instances/{instance_id}``
where ``location_id`` refers to a GCP region.
This corresponds to the ``instance`` field
on the ``request`` instance; if ``request`` is provided, this
should not be set.
reschedule_type (google.cloud.memcache_v1beta2.types.RescheduleMaintenanceRequest.RescheduleType):
Required. If reschedule type is SPECIFIC_TIME, must set
up schedule_time as well.
This corresponds to the ``reschedule_type`` field
on the ``request`` instance; if ``request`` is provided, this
should not be set.
schedule_time (google.protobuf.timestamp_pb2.Timestamp):
Timestamp when the maintenance shall be rescheduled to
if reschedule_type=SPECIFIC_TIME, in RFC 3339 format,
for example ``2012-11-15T16:19:00.094Z``.
This corresponds to the ``schedule_time`` field
on the ``request`` instance; if ``request`` is provided, this
should not be set.
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.

An object representing a long-running operation.
