Hi guys, as I know, when replication filter used, the defered events is a container hold on events(such as Intvar-, Rand-, User_var- log_event)that be applied delay. why those events need be applied delay? and what is parent Query mentioned in codes?

As far as I remember, it's was introduced to do filtering correctly. When not all events should be applied, like with --replicate-do-db. The "parent Query" is the Query event that follows this, say, User_var event. The User_var event should not be executed when its "parent" Query event is filtered out. Regards, Sergei
