   Verified the speed improvement on the [example](https://pastebin.com/pSkYHQn9) provided above. Thanks for the good work! @edponce 
   
   I have one question, does the change revises the arrow file and saves necessary information in the file? Or is it simply does not touch the arrow file structure but just resolve the index with more efficient search? I asked this because I experienced longer access time for existing large multi-chunk arrow file with the change.
