Resilience4j is lightweight alternative to Netflix Hystrix.
Resilience4j is a lightweight, easy-to-use fault tolerance library inspired by Netflix Hystrix, but designed for Java 8 and functional programming. Lightweight, because the library only uses Vavr (formerly Javaslang), which does not have any other external library dependencies. Netflix Hystrix, in contrast, has a compile dependency to Archaius which has many more external library dependencies such as Guava and Apache Commons Configuration. With Resilience4j you don’t have to go all-in, you can pick what you need.
Resilience provides several core modules and add-on modules:

resilience4j-circuitbreaker: Circuit breaking
