What is the best way to store waiting users?

Question

API

I make a video chat with a random selection of interlocutors (as well as with the choice of parameters, age, etc.). and I think how best to store users waiting for a choice? It follows from here that sockets are better or maybe just a set of rests? DB or memory storage?

Answer 1

I think that here the case is just for sockets. And to store, of course, in memory.
