The CAP theorem comes up a lot in backend development. But I think many iOS developers that do any sync/CloudKit work would benefit tremendously understanding it.
It is possible you have a mental model of what “sync” is that has been proven impossible to build.
I wonder what kind of sync iOS devs even build to deal with this. Must be manual, otherwise the cloud sync API will deal with retries on dropped connections, for example?
@ctietze I have never done sync before. I just see a lot of people talking about it recently.
I have heard of people using CRDTs to help here, and I’m in favor of that as a concept. But embracing eventual consistency is something that can be extremely hard to do.
@mattiem I think far more stressful is “hey this is definitely fucking impossible for reasons only my intuition is able to tell me until I sink a bunch of time on it”
so I think everyone is going to come out ahead eventually here
