> is this something we can change (aka update the using join to produce columns and then rely on projection pushdown to prune the uneeded ones out?) That's a good point, the single column output semantic doesn't need to be enforced at the join node level. let me give this a try as well :+1: This could simplify our join handling logic. I will also double check to see if this would result in nontrivial runtime overhead for us. -- This is an automated message from the Apache Git Service.
