Bases: :class:`airflow.operators.check_operator.CheckOperator`
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.

Bases: :class:`airflow.models.BaseOperator`
Fetches the data from a BigQuery table (alternatively fetch data for selected columns)
and returns data in a python list. The number of elements in the returned list will
be equal to the number of rows fetched. Each element in the list will again be a list
where element would represent the columns values for that row.
**Example Result**: ``[['Tony', '10'], ['Mike', '20'], ['Steve', '15']]``

.. note::
If you pass fields to ``selected_fields`` which are in different order than the
order of columns already in
BQ table, the data will still be in the order of BQ table.
For example if the BQ table has 3 columns as
``[A,B,C]`` and you pass 'B,A' in the ``selected_fields``
the data would still be of the form ``'A,B'``.

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.
