[GitHub] [arrow] pitrou commented on pull request #15041: GH-14937: [C++] String Sort / Rank Benchmarks

   Hmm, this seems wrong:
   ```
   ArraySortIndicesString/49152/1                  5.20 us         5.20 us       133594 bytes_per_second=8.79969G/s items_per_second=590.537M/s null_percent=100 size=49.152k
   ```
   For a string array with 100% nulls, the data buffer will probably be empty (meaning we should take the offsets into account after all?).
