## Which issue does this PR close? - Closes #23290. ## What changes are included in this PR? In two commits: * Improve the robustness of `WindowTopN` to intermediate `RepartitionExec` nodes, to ensure that `PartitionedTopK` can still be used when `target_partitions` mismatches physical partitions. * Use `required_input_distributions` to declare required partitioning for `PartitionedTopKExec`, `BoundedWindowAggExec`, and `WindowAggExec`. ## Are these changes tested? Yes, new `slt` tests are added for both the `WindowTopN` robustness fix, and for the use of `required_input_distributions` in `PartitionedTopK`. ## Are there any user-facing changes? No: only plan changes. -- 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.
