> The idea LGTM. Does it apply to other join types? @cloud-fan - I think we can apply similar thing to INNER and LEFT/RIGHT OUTER join, as long as the join does not have extra join condition. But for INNER and OUTER join, we need to output every matching rows from build side, so we need some extra data structure to indicate number of rows per unique join key (similar to `BitSet` as we introduced in `ShuffledHashJoinExec.fullOuterJoinWithUniqueKey`). Shall I make the change later in another PR, for INNER and LEFT/RIGHT OUTER join? -- This is an automated message from the Apache Git Service.
