> These are great optimization opportunities. I’m curious how you arrived at them. We have been running microbenchmarks in the Comet subproject, comparing Spark vs Spark + Comet (queries accelerated with DataFusion), and have identified some expressions where Comet performance is worse than Spark. See https://github.com/apache/datafusion-comet/issues/2986. For the optimizations themselves, it has been a mix of manual effort and the use of Claude code. -- This is an automated message from the Apache Git Service.
