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
