> Join can only specify join keys based on the columns in Project[0]: if b isn't in Project[0], you can't reference it in Join. This was the context I was missing (this is different than SQL for example). Given this context I believe your fix will work correctly (I'm going to merge it) > Further digression: the ScanNode ToString method doesn't print anything useful, so we can't verify what filter and column predicates it has. I thought I filed an issue about that at some point but I can't find it now. I've added https://github.com/apache/arrow/issues/34625 to make sure we handle this in the new scan node. -- This is an automated message from the Apache Git Service.
