Subject Re: Using IAM auth token for sql_alchemy
Date Thu, 22 Aug 2019 11:25:21 GMT
The sql_alchemy_conn_cmd will only get called once at process (scheduler, webserver) start
up, so that wouldn't work for IAM creds, sadly.

To support this probably needs some deeper changes in Airflow - but I don't have an immediate
idea what they might need to be. It would be nice though
