Comment 4 for bug 1257069

Hi Jeff,

I understand all that, but the problem is not in *locking* (we have all means to allow parallel applying even within a single table). It is in *ordering*. We need each DDL to become effective on every node in exactly the same order, otherwise all this GTID stuff is for naught. Since ATM there is no "commit" operation for MySQL DDL, the only way to ensure the order is to start it in order and wait till it ends without letting anybody else to commit (we call it "total order isolation").

In other words solution to this will require some serious DDL execution hacking.

Regards,
Alex
