I'm working on an app where I need to show the friend's presence ( not all users ), as you can see in the picture below. I read the docs of Firebase, they mentioned about users presence but they don't mention any thing about this scenario. If I use all users presence method then what will I do if the users are more than 1000? it gets the data downloaded on every change which I don't want.
There is an idea if I add multiple listeners for every friend then it will be efficient or not, if not then what will be the best practice for it.
Thanks
