   Update on the Comet 1.1.0 row in the first table: that 525 s on Spark 4.2.0 
came from a build of the `branch-1.1` release branch, not the `1.1.0` release. 
I ran the 1.1.0 release on Spark 4.2.0 (same setup, 103 queries, 2 iterations): 
606 s, vs 613 s on Spark 4.1.3. So Comet 1.1.0 takes the same time on both 
Spark versions, while Comet 1.2.0 is 9% faster on 4.2.0 (488 s vs 532 s).
   
   | Speedup over Spark (total time) | Spark 4.1.3 | Spark 4.2.0 |
   |---|---|---|
   | Comet 1.1.0 | 2.18x | 1.64x |
   | Comet 1.2.0 | 2.51x | 2.04x |
