Q:

Is there any way to sync between realm object database with mariadb?

I want to use synchronization between mysql and realm database.is there any option or connector to achieve this . 

A:

There is no option or connector, you would have to make one yourself. 
I assume that you are trying to build your app so that it has offline capabilities. Daniel Causer is a master in constructing Offline capabilities to apps where he talks about just that, here. He's also available on twitter and enjoys answering questions
