    """This API allows users to manage their flat-rate BigQuery
    reservations.

    A reservation provides computational resource guarantees, in the
    form of `slots <https://cloud.google.com/bigquery/docs/slots>`__, to
    users. A slot is a unit of computational power in BigQuery, and
    serves as the basic unit of parallelism. In a scan of a
    multi-partitioned table, a single slot operates on a single
    partition of the table. A reservation resource exists as a child
    resource of the admin project and location, e.g.:
    ``projects/myproject/locations/US/reservations/reservationName``.

    A capacity commitment is a way to purchase compute capacity for
    BigQuery jobs (in the form of slots) with some committed period of
    usage. A capacity commitment resource exists as a child resource of
    the admin project and location, e.g.:
    ``projects/myproject/locations/US/capacityCommitments/id``.

        order to reserve BI capacity it needs to be updated to an amount
        greater than 0. In order to release BI capacity reservation size
        must be set to 0.

            request (:class:`google.cloud.bigquery_reservation_v1.types.UpdateBiReservationRequest`):
                The request object. A request to update a BI
                reservation.
            bi_reservation (:class:`google.cloud.bigquery_reservation_v1.types.BiReservation`):
                A reservation to update.
                This corresponds to the ``bi_reservation`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            update_mask (:class:`google.protobuf.field_mask_pb2.FieldMask`):
                A list of fields to be updated in
                this request.

                This corresponds to the ``update_mask`` 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.
