Hi! What is the recommended way to do circuit breakers with arrow? I have a project with arrow core but I am not to eager to add resilience4j, because it brings vavr and it is going to be confusing to mix with arrow.

[simon.vergauwen]

Are you using it with Reactor in Spring Boot?

[simon.vergauwen]

Does the Resillience4J Reactor dependency also come with VAVR?

[Nicolas Lattuada]

Yes

we dont use reactor yet

[simon.vergauwen]

Oh I see resilience4j-core uses VAVR.

[simon.vergauwen]

Give me a second. I’ll try to whip a simple example.

[simon.vergauwen]

Albeit a small example, but this could be build out to include all features of Resilience4J.
I just created a simple enum to model the state of my CircuitBreaker which wrapped in a class to expose a convenient API.

I use Ref so this can be changed to work with F based on MonadDefer<F> as well.
