So in Spark the physical query plan doesn't have additional Projection under Join operator for the join key expressions, in generally we would like to keep it as it without changing the query plan structure to avoid introducing unknown issues or performance regressions. As this PR relaxes the join key constraints for DataFusion Join operators, we don't need to add such Projection during translating Spark query plan in Comet. -- This is an automated message from the Apache Git Service.
