How nested transactions are handled by Phalcon in MySQL?
As far as I know MySQL don't support nested transactions. However MySQL 5.0.3 and up provides server-side support for XA transactions when using InnoDB engine.
I have MySQL 5.5 and am using InnoDB engine. Does Phalcon in such situation automatically use XA transactions?
If not, how nested transactions are handled then? By save points?
