面试限流算法的相关内容

【Java面试】传统行业跳互联网，一定要会这道题：在秒杀场景中，常用的限流算法有哪些？

一位在传统行业工作了 5 年的程序员。去一个互联网公司面试，被问到一个秒杀的场景题。因为之前完全没接触过分布式相关的项目，单单只是问了限流算法都没有回答不上来，于是向我来求助。另外，我把往期分享的视频全部整理成一份500页的PDF面试题解析配套文档，希望能够以此来提高各位粉丝的通过率，如何获取？&n...

面试官：限流算法有哪些？

限流的实现算法有很多，但常见的限流算法有三种：计数器算法、漏桶算法和令牌桶算法。1.计数器算法计数器算法是在一定的时间间隔里，记录请求次数，当请求次数超过该时间限制时，就把计数器清零，然后重新计算。当请求次数超过间隔内的最大次数时，拒绝访问。计数器算法的实现比较简单，但存在“突刺现象”。突刺现象是指...

面试常见问题-限流策略有哪些，滑动窗口算法和令牌桶区别，使用场景

参考思路：限流算法常用的几种实现方式有如下四种：计数器、滑动窗口、漏桶和令牌桶；● 计数器：○ 思想：在固定时间窗口内对请求进行计数，与阀值进行比较判断是否需要限流，一旦到了时间临界点，将计数器清零。○ 问题：计数器算法存在“时间临界点”缺陷。比如每一分钟限制100个请求...
