If my application in Firebase has 5 users and all of them have a valueListenerEvent on, waiting for some change in the database, do I have 5 connections at the same time? For example, in a chat using firebase with 105 users connected at the same time, are these 105 connections at the same time, ie 5 users are "down" and can not connect? Or is not this the way the firebase counts connections concurrently?
