I think this might be useful for my work as well, so I'm reading up on lateral join as well. I found the answer at https://stackoverflow.com/a/28557803 useful to better understand the difference between lateral joins and correlated subqueries. TL;DR correlated subquery is one value per input row while lateral join supports multiple columns and multiple rows per input row. I'll try to find some more time to review this proposal soon. -- This is an automated message from the Apache Git Service.
