XD-DENG commented on issue #4933: [AIRFLOW-4111] Auto config airflow_db to database in initdb URL: https://github.com/apache/airflow/pull/4933#issuecomment-473927612 Hi @zhongjiajie I have had a quick check. I think it's changing the behaviour, and may cause concern (in my person opinion): Users have been used to the behaviour that all the default connections are somehow "fake" and they know that they need to go there configure explicitly. Another example: I may be using a `read+write` DB account for `sql_alchemy_conn` (`write` permission must be provided), while I will use a `read_only` DB account for `airflow_db`. But your change will use the `read+write` DB account info in `sql_alchemy_conn` to configure `airflow_db`, which should not happen by default. IMO, the concerns this PR brings > the pros it brings (also given that `Data profiling/Ad Hoc Query/Known Events` are all deprecated). Personally I would not merge it. Hope this clarifies.
