Thanks for your super detailed feedback, that was very interesting to read!
A timeout message at which level? At the LiveView level? And how could changes be broadcast directly to the clients without going through the LV process?
How would you implement debouncing then? In my current solution, I update the state to keep track of it needing to be updated, so this call that happens once every second is not really costly at all 
True, using some kind of diffing would obviously be ideal here. But again, I’m using LiveView, so it kinda has to go through that. Can you recommend a way to do diffing in Elixir?
I might have overstated what happened by using the term “crash” It froze for a few seconds until the OOM killer came in.
