Cross-posting from #5492 for visibility. I've been working toward general unnesting and wrote up an incremental plan for getting there, which targets one subquery shape at a time, with each shape serving as a verifiable checkpoint. https://docs.google.com/document/d/1rZoOeiNcJw0OLSDgSqjA7PoA8cf2yAvU6Bc-4o4K4L4/edit?usp=sharing The shapes the current decorrelator gets wrong or can't plan are in the companion Shape Catalog. https://docs.google.com/document/d/10dQRna0Dc8XBB74SkKbfKvPE1SvjNkXKMAcPeK8DiEw/edit?usp=sharing I'm also working on a decorrelation design doc, which I'll post once ready, as a starting point for the generic fix and its implementation. -- This is an automated message from the Apache Git Service.
