> @potiuk agree that we don't need to decrease it now. my concern is more in the future changes. I think we should be more careful when changing the database schema, as it has implications for users when upgrading. Agreee. I think we;ve learned something. Back then when it was changed (before me as committer) we become super careful - we have now not only much better migrations (including being able to go back and forth), automated testing of upgrade and downgrade on CI and very careful reviews of what has changeed precisely beceuse we learned from that experience. Collation and index length for MySQL was something that gave us a lot fo trouble. You are complaining about a change that was implemented ~3 years ago (you simply were a bit disconnected since). Check out those: * https://github.com/apache/airflow/pull/12591 * https://github.com/apache/airflow/pull/14535 * https://github.com/apache/airflow/pull/17603 * https://github.com/apache/airflow/pull/17603 * https://github.com/apache/airflow/pull/17729 * https://github.com/apache/airflow/pull/18072 * https://github.com/apache/airflow/pull/19268 BTW. Speaking of migratioins. If you want to avoid troubles I heartily recomend to move to Postgres. You will not regret it. MySQL is a really bad choice you shoulld reconsider at AirBnB. -- This is an automated message from the Apache Git Service.
