> I will be honest I didn't fully follow this Thanks for reading it — sorry it was so long. Quick answers: - **"filter chain" clarification**: That wasn't a suggestion for arrow-rs — arrow-rs already does this correctly. I meant my own experiment wired the flag into the wrong constructor, so I only measured ~2% of the opportunity. Just a gotcha I ran into, nothing to change on your end. - **Anything small worth pursuing?** **No.** The kernel is fast and that turns out not to matter. - **Next**: I'd like to pick up #8846 (adaptive Mask/Selectors). Also happy to measure predicate-cache cost/benefit if that'd be useful — I've got the benchmark setup ready. - **Blog arc**: "I'm thinking a debugging/methodology style post rather than a performance tuning guide. Something like "how to tell if your optimization is running at all" — coverage counters, probe tests, and the gotchas I hit along the way. Does that direction sound right to you? -- This is an automated message from the Apache Git Service.
