    credentials : google.auth.credentials.Credentials, optional
        Credentials for accessing Google APIs. Use this parameter to override
        default credentials, such as to use Compute Engine
        :class:`google.auth.compute_engine.Credentials` or Service Account
        :class:`google.oauth2.service_account.Credentials` directly.

        *New in version 0.8.0 of pandas-gbq*.
    use_bqstorage_api : bool, default False
        Use the `BigQuery Storage API
        <https://cloud.google.com/bigquery/docs/reference/storage/>`__ to
        download query results quickly, but at an increased cost. To use this
        API, first `enable it in the Cloud Console
        <https://console.cloud.google.com/apis/library/bigquerystorage.googleapis.com>`__.
        You must also have the `bigquery.readsessions.create
        <https://cloud.google.com/bigquery/docs/access-control#roles>`__
        permission on the project you are billing queries to.

        This feature requires version 0.10.0 or later of the ``pandas-gbq``
        package. It also requires the ``google-cloud-bigquery-storage`` and
        ``fastavro`` packages.

    max_results : int, optional
        If set, limit the maximum number of rows to fetch from the query
        results.

        *New in version 0.12.0 of pandas-gbq*.

        .. versionadded:: 1.1.0
    progress_bar_type : Optional, str
        If set, use the `tqdm <https://tqdm.github.io/>`__ library to
        display a progress bar while the data downloads. Install the
        ``tqdm`` package to use this feature.

        Possible values of ``progress_bar_type`` include:

        ``None``
            No progress bar.
        ``'tqdm'``
            Use the :func:`tqdm.tqdm` function to print a progress bar
            to :data:`sys.stderr`.
        ``'tqdm_notebook'``
            Use the :func:`tqdm.tqdm_notebook` function to display a
            progress bar as a Jupyter notebook widget.
        ``'tqdm_gui'``
            Use the :func:`tqdm.tqdm_gui` function to display a
            progress bar as a graphical dialog box.

        Note that this feature requires version 0.12.0 or later of the
        ``pandas-gbq`` package. And it requires the ``tqdm`` package. Slightly
        different than ``pandas-gbq``, here the default is ``None``.
