@antxxxx I believe that most people add their `etl_timestamp` as a column to the table itself. In some scenario it's even the partition field of the table.
I think the better approach is to ask Google to add support for Description & Column description in their CLI commands. Currently it's supported only manually from the UI. https://cloud.google.com/support/docs/issue-trackers Once google will add this feature it will be possible to modify the Airflow Operator to support it. I don't think there should be a separated operator just for this option.
