    """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``.
