             Summary: [C++] Investigate RecordBatch sort performance
                 Key: ARROW-10796
                 URL: https://issues.apache.org/jira/browse/ARROW-10796
             Project: Apache Arrow
          Issue Type: Wish
          Components: C++
            Reporter: Antoine Pitrou
            Assignee: Antoine Pitrou


A RecordBatch is currently sorted as a one-chunk Table. It is suboptimal as it's paying the chunk resolution cost even though it's not necessary.

A dedicated RecordBatch sort may also form the basis for a faster Table sort (first sort individual batches, then use merge sort along the sorted batches).
