> 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).
