Resilience4j 是一个轻量级的容错组件,其灵感来自于 Hystrix,但主要为 Java 8 和函数式编程所设计。轻量级体现在其只用 Vavr 库(前身是 Javaslang),没有任何外部依赖。而 Hystrix 依赖了 Archaius ,Archaius 本身又依赖很多第三方包,例如 Guava、Apache Commons Configuration 等。
限速组件架构:
Resilience4j 提供了如下几款核心组件
•
resilience4j-circuitbreaker: Circuit breaking
•
resilience4j-ratelimiter: Rate limiting
•
resilience4j-bulkhead: Bulkheading
•
resilience4j-retry: Automatic retrying (sync and async)
•
resilience4j-cache: Response caching
附件组件包括:
•
resilience4j-reactor: Spring Reactor adapter
•
resilience4j-rxjava2: RxJava2 adapter
•
resilience4j-micrometer: Micrometer Metrics exporter
•
