danny0405 commented on issue #1703: WIP: [CALCITE-2450] Reorder RexCall 
predicates to a canonical form
URL: https://github.com/apache/calcite/pull/1703#issuecomment-569617661
 
 
   How many changed plans there can have a performance promotion ? I would say 
very few. We can do some promotion code and that is awesome, but please **do 
not bring in** extra burden to the users that do not need this feature.
   
   > In other words, the plan would be sorted in exactly the same order, so the 
change would make plans more stable in the future.
   
   I don't think so, isn't keep the rex calls the sequence just as what user 
writes them more natural, more readable more stable ?
