UnverifiedExponential backoff is a strategy in which the client progressively lengthens the waiting interval when retrying failed requests, mainly addressing two types of problems: rate limiting (HTTP 429) and brief unavailability of downstream services; compared with fixed-interval retries, it can significantly reduce pressure on services that are already overloaded.79% similarUnverifiedCombining an exponential backoff strategy can avoid the thundering herd effect caused by a large number of retry requests at the moment a service recovers77% similarUnverifiedCascading failure is a typical failure mode in distributed systems: when a component responds slowly due to excessive load or an anomaly, upstream services keep retrying or piling up requests, thereby transmitting pressure to other dependent components and ultimately causing large-scale unavailability.75% similarUnverified级联失效的根本原因通常在于服务间的强耦合与缺乏熔断机制，上游服务响应超时会导致下游线程池被阻塞请求耗尽74% similar
