Resilience4j v0.13.2 发布，面向 Java 8 和函数式编程的容错库

Resilience4j v0.13.2 发布了，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。

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

限速组件架构：
