Re: [I] Expects PARTITION BY expression to be ordered in DataFusion 51 release [datafusion]

linhr commented on issue #18527:
URL: https://github.com/apache/datafusion/issues/18527#issuecomment-3823496543

   This turns out to be an issue within Sail when certain distributed query plans are constructed incorrectly, causing validation to fail for `BoundedWindowAggExec`. So nothing goes wrong in DataFusion.
   
   The issue was only noticed after DataFusion 51, possibly due to how validation/optimization logic changed recently for physical planning in DataFusion.
   
   @alamb Feel free to close this issue!
