class FirestoreAdminAsyncClient:
    """The Cloud Firestore Admin API.

    This API provides several administrative services for Cloud
    Firestore.

    Project, Database, Namespace, Collection, Collection Group, and
    Document are used as defined in the Google Cloud Firestore API.

    Operation: An Operation represents work being performed in the
    background.

    The index service manages Cloud Firestore indexes.

    Index creation is performed asynchronously. An Operation resource is
    created for each such asynchronous operation. The state of the
    operation (including any errors encountered) may be queried via the
    Operation resource.

    The Operations collection provides a record of actions performed for
    the specified Project (including any Operations in progress).
    Operations are not created directly but through calls on other
    collections or resources.

    An Operation that is done may be deleted so that it is no longer
    listed as part of the Operation collection. Operations are garbage
    collected after 30 days. By default, ListOperations will only return
    in progress and failed operations. To list completed operation,
    issue a ListOperations request with the filter ``done: true``.

    Operations are created by service ``FirestoreAdmin``, but are
    accessed via service ``google.longrunning.Operations``.

                not explicitly provided. Only if this property is not set and

                2. If the GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable
                is "true", then the ``client_cert_source`` property can be used

                set, no client certificate will be used.

                3. The ``universe_domain`` property can be used to override the
                default "googleapis.com" universe. Note that ``api_endpoint``
                property still takes precedence; and ``universe_domain`` is
