This is the query
```
SELECT l_linenumber, l_partkey
FROM lineitem
ORDER BY l_linenumber
```
So it might actually be the case that the changed code is a bit slower for
this case. In the query there is only little data to copy (so concat batches ->
concat sort keys doesn't help that much) while maybe the overhead of using
interleave_batches is higher 🤔
