All regression tests now pass with the new bounded-memory sort code. There is still lots of opportunity for optimization, however. (CVS 2654) (check-in: 81259a01 user: drh tags: trunk)
03:07
Sorting is now done using a sorting index rather than loading the entire result set into memory and doing a merge sort. The old merge sort technique was a carry-over from SQLite version 1. The new method uses a bounded amount of memory and scales to much larger result sets. There are still errors: some 39 regression tests fail. (CVS 2653) (check-in: 09db0a24 user: drh tags: trunk)
