[GitHub] [arrow] jjyao commented on issue #35126: [Python][C++] Slow table slice when the table has many chunks

   > Maybe there could be some optimization when you are taking a slice that covers several chunks entirely, we don't actually call Slice on the chunks that are needed in full for the result.
   
   In my script, we actually do slice a single chunk (equal to `batch_size`).
