Unclear documentation around "channels"

[MatanYemini]

Hi!

1 question:

From what it seems that channels are according to "namespace" only, and not by roomId.

e.g:

this.channel = prefix + "#" + nsp.name + "#"; this.requestChannel = prefix + "-request#" + this.nsp.name + "#"; this.responseChannel = prefix + "-response#" + this.nsp.name + "#"; this.specificResponseChannel = this.responseChannel + this.uid + "#";

But, in the README.md file, you are suggesting prefix + '#' + namespace + '#' + room + '#' will be the way to distribute a message to a specific room.

I would also add what is the behavior when subscribing to a channel. For example, if room A is at server 1 and room B is at server 2, does sever1 will receive messages that are related to server2 (the load-balancer somehow magically did that each room belongs to 1 server, leave the optimization aside of that ;) )

It's implemented only in the sharded redis adapter? from the code it seems like, but not from the docs

Thanks! Please let me know if I can help somehow with the questions above :))
