[GitHub] [arrow-datafusion] mingmwang commented on issue #5970: UNION ALL with ORDER BY results are inconsistent

   My suggestion is making the partition-aware optimization a configure option, but do not remove the code. 
   By default, we turn it off. So that the UnionExec just like a plain Union and do not keep the partition info.
