Get the list of all the ids of room across different servers

[StevenRoan]

I've distributed socket.io processes to multiple servers to scale up my service, and I need to get all the ids of rooms that exist in different servers.

I know we can get the rooms name in single process by

Object.keys(io.sockets.adapter.rooms)

but I cannot get the information of the rooms in other server by socket.io it self.

So far, I noticed that there are several related discussions and pull request:

Automattic/socket.io#1811
Automattic/socket.io-redis pull#15

My questions are:

• What I mentioned is correct or not?
• Should socket.io include some inter-server communication mechanism to let user get the information from other server? Or this kind of adapter should be implemented in each customized adapter itself as mentioned in the Introduction of Sokcet.io 1.0 # Scalability
