@comphead, I debugged this behaviour also. It seems that during concatenation in the `BoundedWindowAggExec`. We were effectively using the `schema` of the first batch in the partition (The schema of the first batch may not reflect the worst case scenario. As in this example, first batch may come from one of the input branches of the `union` with `is_nullable=false`). I have filed the [PR9508](https://github.com/apache/arrow-datafusion/pull/9508) to fix this problem. If you have time, I would appreciate your review. -- This is an automated message from the Apache Git Service.
