Redis is single threaded. How can I exploit multiple CPU / cores?It’s not very frequent that CPU becomes your bottleneck with Redis, as usually Redis is either memory or network bound. For instance, using pipelining Redis running on an average Linux system can deliver even 1 million requests...
单线程 Redis 如此快的 4 个原因 本文翻译自国外论坛 medium,原文地址:https://levelup.gitconnected.com/4-reasons-why-single-threaded-redis-is-so-fast-414e0106f921 作为内存数据存储,Redis以其速度和性能而闻名,通常被用作大多数后端服务的缓存解决方案。 然而,在 Redis 内部采用的也只是单线程的设计。 ...
官方FAQ表示,因为Redis是基于内存的操作,CPU不是Redis的瓶颈,Redis的瓶颈最有可能是机器内存的大小或者网络带宽。既然单线程容易实现,而且CPU不会成为瓶颈,那就顺理成章地采用单线程的方案了 Redis is single threaded. How can I exploit multiple CPU / cores? It's not very frequent that CPU becomes your b...

《Redis is single threaded. How can I exploit multiple CPU/cores?》 redis.io/topics/faq,说明了redis使用单线程的原因: CPU通常并不是Redis的瓶颈,因为Redis通常要么受内存限制,要么受网络限制。比如说,一般在Linux系统上运行的流水线Redis,每秒可以交付一百万个请求,如果你的应用程序主要使用O(N)或O(log(N...
“为什么单线程的Redis能那么快?”通常说,Redis 是单线程,主要是指Redis 的网络 IO 和键值对读写是由一个线程来完成的,这也是 Redis 对外提供键值存储服务的主要流程。但 Redis 的其他功能,比如持久化、异步删除、集群数据同步等,其实是由额外的线程执行的。
