Hi @zhuqi-lucas , I have opened a PR to address this issue. I implemented the logic in `PushdownSort` to utilize `EquivalenceProperties`. The optimizer now detects if a column in the sort prefix is constant and strips it from the `required_ordering` before attempting the pushdown. I've also added a unit test using a mock plan to verify that the `SortExec` is correctly removed when the prefix is constant. Kindly let me know what you think. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
