Import a Redis RDB snapshot file from GCS into a Redis instance.

        Redis may stop serving during this operation. Instance state will be
        IMPORTING for entire operation. When complete, the instance will contain
        only data from the imported file.

        The returned operation is automatically deleted after a few hours, so
        there is no need to call DeleteOperation.

        Example:
            >>> from google.cloud import redis_v1
            >>>
            >>> client = redis_v1.CloudRedisClient()
            >>>
            >>> name = client.instance_path('[PROJECT]', '[LOCATION]', '[INSTANCE]')
            >>>
            >>> # TODO: Initialize `input_config`:
            >>> input_config = {}
            >>>
            >>> response = client.import_instance(name, input_config)
            >>>
            >>> def callback(operation_future):
            ...     # Handle result.
            ...     result = operation_future.result()
            >>>
            >>> response.add_done_callback(callback)
            >>>
            >>> # Handle metadata.
            >>> metadata = response.metadata()

        Args:
            name (str): Required. Redis instance resource name using the form:
                ``projects/{project_id}/locations/{location_id}/instances/{instance_id}``
                where ``location_id`` refers to a GCP region
            input_config (Union[dict, ~google.cloud.redis_v1.types.InputConfig]): Required. Specify data to be imported.

                If a dict is provided, it must be of the same form as the protobuf
                message :class:`~google.cloud.redis_v1.types.InputConfig`
            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.redis_v1.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.
