> [https://github.com/apache/arrow/pull/7143] is going to add benchmarks to arrow-reader-writer-benchmarks, but these only cover dictionary encoded cases.  It is hard to force non-dictionary encoding so we should try to write some benchmarks that give a better sense of how that path changes with any algorithm changes.
>  
> It isn't clear how much this code path is exercised in practice so I'm not sure on the priority.
