circuit-breaker

Retries alone can make an outage worse: if a dependency is hard failing, retries just add load. A circuit breaker adds a simple state machine: closed (normal), open (fail fast), and half-open (probe). I like gobreaker because it’s small and predictabl

Resilience4j provides resilience patterns for fault tolerance. Circuit breakers prevent cascading failures—open after threshold failures, allow retry after timeout. Rate limiters control request rates. Retry mechanisms handle transient failures. Bulkh
