Relay replacement for Redux for React?

Question

React

I read about Relay, the ideas are similar to Redux.
Is it like Facebook decided to write their own analogue of Redxu (Flux) for React?
Or I misunderstood?

Answer 1

Relay is a framework for communicating with servers via the Graphql API and supporting a client-side data cache, Redux is a global client/component state store.

Answer 2

Facebook came up with the Flux approach before Redux.
And then also Relay. I don't know if they were looking at Redux at the time or not.
