Emq mqtt clustering : Client Session management

Question

I've gone through the documentation for emq clustering but i couldn't find a clear explanation for how session management is done. I understand topics table is shared among clustered nodes but client connection information is not? What happens if a node goes down? Would it loose all the info about client sessions it was managing?

Answer 1

The route is shared in the cluster, and the session is stored on the connected node. If the node goes down and the client reconnects, the session will be lost.
