Hi! Not sure if this is the proper place for this question; of not please let me know.
We're running airflow on a mariadb/galera cluster, and we 're using haproxy to provide HA connections. Sometimes (mostly due to maintenance) one node is temporarily unavailalble, which forces haproxy to drop connections to this node after which new connections are passed to another (still running) node. This is quite common, and we use it for other software too. See https://galeracluster.com/library/documentation/ha-proxy.html.<https://galeracluster.com/library/documentation/ha-proxy.html> for more info. The issue we're running into however is the fact that airflow gets lost in this situation which to airflow is something like a dropped connection. airflow services seem to be running (they themselves thing they are running) but they're just stuck. So they don't do anything, but we don't know. Aiming at a HA setup, this is deffinitely not what we want. Colleages actually are now at the point that they disqualify airflow. Of course I can provide more details if needed, but I'd like to know first if this is the right place to bring this up. Best, Rolf
