Improving Resilience Using Resilience4j
In this chapter, we will learn how to use Resilience4j to make our microservices more resilient, that is, how to mitigate and recover from errors. As we already discussed in Chapter 1, Introduction to Microservices, in the Circuit breaker section, and Chapter 8, Introduction to Spring Cloud, in the Using Resilience4j for improved resilience section, a circuit breaker can be used to minimize the damage that a slow or unresponsive downstream microservice can cause in a large-scale system landscape of synchronously communicating microservices. We will see how the circuit breaker in Resilience4j can be used together with a time limiter and retry mechanism to prevent two of the most common error situations: ...
