Scalability of y-websocket server

Hi @dmonad, can you write a tutorial on scaling y-websocket horizontally? I was initially planning to use sharedb, but the delay in subscribe-queries acknowledging new records and the 16MB mongo-db doc limit have made me look elsewhere for the collaborative diagramming tool I am working on.

I like y-js, but not having any clear guide on how to scale y-websocket horizontally is holding me back. It’d be very helpful if you can finish this page: https://docs.yjs.dev/tutorials/untitled-3
