System design - Redis & HTTP william AI Recommendation/LLM 1 人赞同了该文章 Why redis is fast 基于内存 优势: High read/write throughput, Low latency 劣势: Dataset cannot be larger than memory 代码简洁 2.IO多路复用 + 单线程 3. 高效的数据结构 基于redis优化的cache: Dragonfly, keyDB HTTP 加...
更新缓存的的Design Pattern有四种:Cache aside, Read through, Write through, Write behind caching,我们下面一一来看一下这四种Pattern。 1. Cache Aside Pattern 这是最常用最常用的pattern了。其具体逻辑如下: 失效:应用程序先从cache取数据,没有得到,则从数据库中取数据,成功后,放到缓存中。 命中:应用程序从...
