I believe our main issue is because we are using
session.close()
instead ofsession.remove()
and because each scheduled run is in it own thread we should be usingscoped_session
as well. This seems to work fine in my tests, but will be hard to tell for sure until we do a deployment with this code to see if it actually resolves our connection issues.https://docs.sqlalchemy.org/en/13/orm/contextual.html#contextual-thread-local-sessions
