[GitHub] [spark] DenineLu commented on pull request #35806: [SPARK-38505][SQL] Make partial aggregation adaptive

DenineLu commented on PR #35806:
URL: https://github.com/apache/spark/pull/35806#issuecomment-1336634413

   I was interested in working on this, but I tested it with an online production task and found that the performance was regressing. Even though the aggregation time is shortened, the whole stage is more time consuming. Have you encountered this situation please?
