Thx, Julian Why not just support non-equi join condition for every physical algorithm, it does not make much sense if we have both HashJoin and a HashTheraJoin, cause a HashThataJoin with empty non-equi join condition is same as a HashJoin.
And we can remove the limitations in the rule like FilterJoinRule.
