Rate Limiting About State of the art rate-limiting in Java. Implemented algorithms: Token bucket algorithm Fixed window algorithm Sliding window log algorithm Highly customizable and extensible implementation with assumptions about the environment used - it can be easily extended to be used with any ke...
bucket4j ならびに bucket4j-spring-boot-starter を用いると、かなり簡単に既存の Spring Boot アプリケーションに Rate-Limiting の機能を追加することができる。 本格的に Rate-Limiting の処理をシステム全体に適用する場合は、Ambassador Pattern や Side-Car Pattern を用いて API Gateway のミドル...
Each time a request comes in, we log the time. If it hasn't been a certain duration since the last request, then abort with a rate-limiting error. key = create_key(request) entry = gate.get_entry(key) if (entry) response.set_status(SERVICE_UNAVAILABLE) return end entry = create_ent...

假如超过服务能力,一般会造成整个接口服务停顿,或者应用挂了,将延迟传递给服务调用方造成整个系统的服务能力丧失。要是对外的公开 API 接口服务,Rate limiting 应该是一个必备的功能,否极有可能被恶意调用导致服务宕掉,所以限流是必要的。这里本文就整理下常见的限流原理及方案。
