Thanks for sharing the results @zhuqi-lucas this is really interesting! I think it mainly shows that we probably should try and use more efficient in memory sorting (e.g. an arrow kernel that sorts multiple batches) here rather than use `SortPreservingMergeStream` which is intended to be used on data streams. The arrow kernel would avoid the regressions of `concat`. -- This is an automated message from the Apache Git Service.
