@hsyuan any suggestions on how hash join (maybe also nested loop join) traits derivation should be tested? I am thinking doing this ``` select * from (select distinct a, b from foo) foo join bar on foo.c = bar.c ``` Then the produced plan might add a Sort on top of Select. Do you think it is right? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
