Notes on the patch:
- Applies to VARCHAR cols, text/blob is still not handled.
- it is only enabled if you use a special create table option
- it only works for variable width columns in a table after any indexed columns
- thus not supported for automatic temporary tables - investigate this, see if col swapping might be feasible! |
See http://code.google.com/p/mysql-heap-dynamic-rows/
Patch is on MySQL 5.0 codebase.
