### Is your feature request related to a problem or challenge?
We should investigate and improve the sort code to support concat_batches
for more cases besides the following case:
```rust
// If less than sort_in_place_threshold_bytes, concatenate and sort
in place
if self.reservation.size() < self.sort_in_place_threshold_bytes {
// Concatenate memory batches together and sort
let batch = concat_batches(&self.schema, &self.in_mem_batches)?;
self.in_mem_batches.clear();
self.reservation
.try_resize(get_reserved_byte_for_record_batch(&batch))?;
let reservation = self.reservation.take();
return self.sort_batch_stream(batch, metrics, reservation);
}
```
See details about the performance improvement:
