Now, if you just want to have the backfill command but don’t want users to have access to the host terminal, I found this nifty backfill plugin that will open up that command through a view. Looks like it is triggering the backfill command in the background on the webserver host (though that’s probably not ideal).
Regardless, this just shows you that there are many ways to perform backfills because of how customizable Airflow is.
