@derek_knox thank you for the information. I will take a closer look. Something that didn't feel right and I think that I should share with you is airflow. I have spend many hours to install it without any broken parts (standalone without meltano). It seems that will be a huge headache for you. Also I think that meltano installs airflow with sqllite which doesn't support big data and that you need to use postgre or MySQL. I managed to use postgre, with MySQL even the latest version had a lot.of problems.

Thanks for the share, we are aware of some of the challenges cc @micael_bergeron @yannis_roussos
