class BigQueryCheckOperator(_BigQueryDbHookMixin, SQLCheckOperator):
    """
    Performs checks against BigQuery. The ``BigQueryCheckOperator`` expects
    a sql query that will return a single row. Each value on that
    first row is evaluated using python ``bool`` casting. If any of the
    values return ``False`` the check is failed and errors out.

    .. seealso::
        For more information on how to use this operator, take a look at the guide:
        :ref:`howto/operator:BigQueryCheckOperator`

    Note that Python bool casting evals the following as ``False``:

    * ``False``
    * ``0``
    * Empty string (``""``)
    * Empty list (``[]``)
    * Empty dictionary or set (``{}``)

    Given a query like ``SELECT COUNT(*) FROM foo``, it will fail only if
    the count ``== 0``. You can craft much more complex query that could,
    for instance, check that the table has the same number of rows as
    the source table upstream, or that the count of today's partition is
    greater than yesterday's partition, or that a set of metrics are less
    than 3 standard deviation for the 7 day average.

    This operator can be used as a data quality check in your pipeline, and
    depending on where you put it in your DAG, you have the choice to
    stop the critical path, preventing from
    publishing dubious data, or on the side and receive email alerts
    without stopping the progress of the DAG.

    Creates a new external table in the dataset with the data from Google Cloud
    Storage.

    The schema to be used for the BigQuery table may be specified in one of
    two ways. You may either directly pass the schema fields in, or you may
    point the operator to a Google Cloud Storage object name. The object in
    Google Cloud Storage must be a JSON file with the schema fields in it.

        For more information on how to use this operator, take a look at the guide:

        BigQuery table to load data into (templated). If ``<project>`` is not included,

    :type allow_quoted_newlines: bool
    :param allow_jagged_rows: Accept rows that are missing trailing optional columns.
        The missing values are treated as nulls. If false, records with missing trailing
        columns are treated as bad records, and if there are too many bad records, an
        invalid error is returned in the job result. Only applicable to CSV, ignored

class BigQueryInsertJobOperator(BaseOperator):
    """
    Executes a BigQuery job. Waits for the job to complete and returns job id.
    This operator work in the following way:

    - it calculates a unique hash of the job using job's configuration or uuid if ``force_rerun`` is True
    - creates ``job_id`` in form of
        ``[provided_job_id | airflow_{dag_id}_{task_id}_{exec_date}]_{uniqueness_suffix}``
    - submits a BigQuery job using the ``job_id``
    - if job with given id already exists then it tries to reattach to the job if its not done and its
        state is in ``reattach_states``. If the job is done the operator will raise ``AirflowException``.

    Using ``force_rerun`` will submit a new job every time without attaching to already existing ones.
