How do I implement a circuit breaker in my application?

To implement a circuit breaker, you can use libraries like Hystrix or Resilience4j. Do you have a specific programming language in mind?

I'm using Java. Can you provide a code example?

Sure! Here's a simple example using Resilience4j:

CircuitBreaker circuitBreaker = CircuitBreaker.ofDefaults("myCircuitBreaker");

Supplier<String> decoratedSupplier = CircuitBreaker.decorateSupplier(circuitBreaker, () -> riskyCall());

String result = Try.ofSupplier(decoratedSupplier)
                   .recover(throwable -> "Fallback response");

What is the purpose of a circuit breaker?

A circuit breaker prevents an application from repeatedly trying to execute an operation that is likely to fail, thus improving stability.
