[GitHub] [arrow] edponce commented on pull request #12055: ARROW-11989: [C++][Python] Improve ChunkedArray's complexity for the access of elements

   Hi @eelxpeng, the implementation in this PR caches the previous chunk used, so it is expected to be faster than randomly accessing chunks where chunk caching operations add a (small) penalty rather than be useful.
   
   How do your results compare to Arrow before this patch got merged?
