----------------------------------------
Summary: BigQuery Operator flattens the repeated column and it's
not configurable
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.
