Hi dmonad,
Thanks for the pointers, we will also consider y-leveldb. as an adapter.
Thank you also for your offer to help. I think what we will do is do the proof of concept to learn about yjs. We want to see if we can fit it nicely in our AWS infra, perhaps even running the server side on lambda (Although, I can image the in-memory state of YJS in a lambda that comes and goes is perhaps not a good idea). We also also want to test resilience and how it scales.
From there, if we decide yjs is fit for our goals, we can evaluate if your help would benefit us moving quickly forward.
Rgds Christophe
