   > @dongjoon-hyun Thanks for pinging me. Hmm, this is actually related to what we are working on [SPARK-32943](https://issues.apache.org/jira/browse/SPARK-32943). We should not do it at physical plan level. We plan to tackle this kind of issue at optimizer.
   
   All right, I will try to make this resolved  in Optimizer
