I did read up on bug 44927 - auto increment counter, and still not sure if Serg or Zardosht is right. When checking the code, it looks like using HA_AUTO_PART_KEY in the engine is the right way to go. After all, this is just a check if we should allow auto_increment as a secondary part of a key. In this case there is no patch to add to MariaDB. Serg, can you please verify this. Regarding http://bugs.mysql.com/bug.php?id=45458, it would be good to use the new CREATE options we have in 5.2 to store the fact if a key is clustered or not. Serg, would you like to review the patch and see if it can go into 5.2 or 5.3 ? Regards, Monty
