Hi, Cache in Ignite is a cluster wide storage for data. This data will be available around all clients. And it should work similarly for each of them. That's why the configuration can't be changed during runtime on the already started cache.
I don't think that all your clients will use the same data but have different consistency requirements for it. So in your case, I suggest create different caches for every goal/user with required configurations (every cache could have different synchronization mode).
