Here's my problems with MWAA (amazon hosted airflow.) I have about 100 dags which maxes out the scheduler thread. Airflow parses all the files every minute so it's always parsing around 94% cpu. I could run a second scheduler thread if I coordinate with my SRE team and get the terraform deployed...it's really tedious.
Related possibly, my dags get kill -9 for no apparent reason. The RAM usage is not that high, maybe 2gb out of 8gb system RAM in use. No reason is given in the logs.
I am trying to switch to dagster, not because it's awesome, but because it hasn't crashed randomly on me.
