And I think we can not use the HashSet to do the dedup. 1) HashSet might change the ordering of the sort exprs. 2) We should ignore the Sort options(Asc/Desc). For example `select * from t1 order by id desc, id, name, id asc;` The real sort key should be: `Sort Key: id DESC, name` -- This is an automated message from the Apache Git Service.
