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

pitrou commented on PR #12055:
URL: https://github.com/apache/arrow/pull/12055#issuecomment-1114297975

   > Not sure about why. I have a large arrow file with 115545630 rows and 488 chunks. Even using the fix in this pr, the time to randomly access 1000 rows is 2102 seconds
   
   This sounds really huge and unrelated to this PR. Are you accessing the file over local storage or a remote filesystem?
