The circuit breaker pattern switches from closed to open when the failure rate exceeds a threshold, and subsequent requests fail fast directly or take the fallback path; after a cooldown it enters the half-open state to let probe requests through, and returns to the closed state if they succeed.

VerifiedThe circuit breaker pattern originates from the fault-tolerance design philosophy of microservice architecture, automatically interrupting and rolling back when the failure rate exceeds a threshold.79% similarUnverifiedA circuit breaker maintains three states: Closed, in which requests pass through normally and failure rates are tracked; Open, in which all requests immediately fail after tripping; and Half-Open, in which a limited number of probe requests are allowed through after the cooldown period.78% similarUnverifiedThe circuit breaker's default configuration is to open after 5 consecutive failures, close at an 80% recent success rate, and half-open for probing after 60 seconds.78% similarUnverified熔断降级是分布式系统的容错模式，当下游服务连续失败或超时达到阈值时熔断器断开，后续请求直接走降级逻辑，避免故障引发系统雪崩74% similarUnverifiedTraditional circuit breakers follow a three-state model of Closed, Open, and Half-Open, typically triggered based on the failure rate within a time window.73% similar
