zhongjiajie edited a comment on issue #6987: [AIRFLOW-6416] Remove DB provide_session and sort by conn_id URL: https://github.com/apache/airflow/pull/6987#issuecomment-570040683 > @zhongjiajie why do you want to remove @provide_session ? The way it works now, it will create a new session for each connection - each merge_conn will have a new session (which basically means new connection established with the database). With @provide_sesion, the session will be reused whereas with the new approach it will be create/commit/close for every single Connection entry. I think we don't need to create connect in function `create_default_connections`, because it will be create in function `merge_conn`, so I remove it. but when you comment in > We should not remove @provide_session as it is there to make all the connections reuse session rather than recreate sessions. I get that point
