So, how do you actually deal with a ton of people using real-time stuff all at once? It's a big question, right?

were building a new feature that needs real-time updates for thousands of users all at once. think stuff like google docs or live game scores. we looked at websockets and sse, but managing all those connections and keeping things fast seems super hard. what ways or setups have you found work well for making real-time apps handle tons of users at the same time? any specific server stuff, load balancing tricks, or maybe different tech we should check out besides the obvious ones
