Mysql plays it safe and assumes that any table modification requires a full rebuild. 5.1 knows that certain settings don't require a full rebuild, but delay_key_writes isn't one of them (and some that are marked as fast shouldn't be - see http://bugs.mysql.com/bug.php?id=39372 ). -- Dan Nelson dnel...@allantgroup.com -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/mysql?unsub=arch...@jab.org
