Resilience4J. These examples are extracted from open source projects. First, we learned what the Spring Cloud Circuit Breaker is, and how it allows us to add circuit breakers to our application. Resilience4j provides higher-order functions (decorators) to enhance any functional interface, lambda expression or method reference with a Circuit Breaker, Rate Limiter, Retry or Bulkhead. When you work with distributed systems, always remember this number one rule - anything could happen. dinnington high school alumni.
