> Key: AIRFLOW-1410
> URL: https://issues.apache.org/jira/browse/AIRFLOW-1410
> Project: Apache Airflow
> Issue Type: Bug
> Components: contrib, hooks
> Reporter: Pratap Koritala
> Priority: Minor
>
> For Legacy SQL, BigQuery Operator/Hook flattens the repeated column. The underlying Google Query JSON API's parameter "flattenResult" has default value of false, by not setting it every Legacy SQL result is flattened.
> Without this config option, Legacy SQL can't be used for queries with repeated columns. Even though it looks like feature request, I consider this as a bug as this config option should have been in the first place.
> I am working on submitting PR to github project.
