👋 I'm picking back up on this work as part of a directed study for my graduate degree. I put together a doc proposing a correctness target we can implement against which is essentially a catalog of query shapes that the current decorrelator gets wrong (either a hard failure or a plan that returns the wrong answer). This'll give any new implementation something to verify against as it grows. Plan doc: https://docs.google.com/document/d/1rZoOeiNcJw0OLSDgSqjA7PoA8cf2yAvU6Bc-4o4K4L4/edit?usp=sharing Shape catalog: https://docs.google.com/document/d/10dQRna0Dc8XBB74SkKbfKvPE1SvjNkXKMAcPeK8DiEw/edit?usp=sharing I'm working on a theoretical mapping from Neumann's paper to DataFusion's plan structures next. Would appreciate early feedback on the approach before I start building against it. -- This is an automated message from the Apache Git Service.
