Difference Between Circuit Breaker and Retry in Spring Boot

Date: 2025-02-17

Spring Boot offers two crucial resilience patterns for microservices: Retry and Circuit Breaker. Retry repeatedly attempts an operation (useful for transient failures like network glitches), while Circuit Breaker stops repeated calls to a failing service after a threshold is reached, providing a fallback (ideal for persistent failures). Retry uses Spring Retry's @Retryable, and Circuit Breaker leverages Resilience4j's @CircuitBreaker. Choosing between them depends on the failure type; combining both provides optimal fault tolerance, with Retry handling short-term issues and Circuit Breaker preventing cascading failures from persistent ones.
