Resilience4j is a fault-tolerance library implementing the Circuit Breaker pattern inspired by Netflix Hystrix, but offers a more convenient API and a number of other features like Rate Limiter to block too many frequent requests to some services, Bulkhead to limit the number of concurrent requests to a specific service, cacheing, fail retry, and time limiter. Resilience4J is a lightweight ‘fault tolerance’ framework with several functions like a circuitbreaker, rate-limiter, retry-functionality and caching. I've tried the Resilience4J example, but the rate limiter does not seem to obey my demands: @Test public void simpleReactiveWithRateLimiter() { RateLimiterConfig rateLimiterConfig = ... rx-java resilience4j rx-java3. Spring Cloud adds support for Spring MVC annotations and for using the same HttpMessageConverters used by default in Spring Web.
