Shameless plug, we built Chronon to solve a very similar problem. Chronon is now open source (apache 2) and used at Netflix, OpenAI, Airbnb, Stripe etc.
It is used to serve features/context to ML/AI models and rule engines, along with app views.
We are more scale and perf oriented as project given the use-cases and less decentralization oriented.
We also ship with a dataframe / prql like declarative api.
