### What is the problem the feature request solves? Initial observations: - Query is fully native - Similar to q19, lineitem scan takes longer with Comet - Comet avoids an expensive C2R on 600mm rows from lineitem - Looking at the metrics in Spark UI it looks like most operations are faster in Comet, yet the overall query wall clock time is slower - Needs more investigation ### Describe the potential solution _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
