I think CrossJoin is still required as a physical join plan implementation, because for Cross Join we can have different Partitioning/Shuffle strategies(M * N). Of course we can merge all the logic to NestedLoopJoin, but this will make the NestedLoopJoin's partitioning logic very complex(which is already quite complex). -- This is an automated message from the Apache Git Service.
