Hystrix is a Java library for latency and fault tolerance in distributed systems, providing circuit breakers, thread/semaphore isolation, fallbacks, and request collapsing to stop cascading failures. It is now officially in maintenance mode, with Netflix recommending resilience4j for new projects.
Use cases
- stop cascading failures between microservices
- add circuit breakers around remote service calls
- implement fallbacks and graceful degradation
- isolate third-party library calls with bulkheads
- monitor real-time dependency health with dashboards
- add timeouts and fail-fast behavior to remote calls
When to choose
- maintaining an existing JVM application already built on Hystrix
- you need battle-tested circuit breaker semantics on Java 6+
- you rely on its mature dashboard and monitoring integrations
When to avoid
- starting a new project - use resilience4j or similar instead
- you need adaptive, real-time performance-based concurrency limits
- you are not on the JVM
- you expect active maintenance, bug fixes, or new features
