   🤔 Interesting, I'd have expected that maintaining an extra `Uint64Array` 
column would be pretty much 0 cost, as creating it costs compute that we 
anyways needed to do one way or another.
   
   For the clickbench results in both PRs 
(https://github.com/apache/datafusion/pull/23720#issuecomment-5021747597 and 
https://github.com/apache/datafusion/pull/23446#issuecomment-4950574858), I see 
the gains and regressions are so subtle and inconsistent that I could believe 
everything there is within noise.
   
   ClickBench q4 seems to be consistent in regressing, I'll pass that through a 
profiler and see if there's something obvious going on.
