> hash join can just support equal condition. If there is no the equal condition, we can't use the hash join. > If the condition is on left_table.column1 > 10 which can't be used for hash. I was thinking something like you could use a hash table with a single entry when there are no join keys -- which will effectively devolve into a CrossJoin What I really would hope to avoid is another join implementation if possible -- Joins are already complicated enough, and so adding another one will not improve the situation. -- This is an automated message from the Apache Git Service.
