什么是缓存穿透以及常见解决方案缓存穿透是指客户端请求的数据在缓存中和数据库中都不存在，这样缓存永远不会生效，这些请求都会打到数据库，导致数据库压力提高，造成宕机。缓存穿透就是指用户访问那些在数据库和Redis中都不存在的数据，例如我们知道id采用自增策略，那么就不可能出现负数id，而如果不法分子使用负数id进行查询，那么这些请求都会穿过Redis直接向数据库发送请求，从而导致数据库压力骤增，导致数
Redis 为什么这么快？小海海不怕困难 Redis redis
决定Redis请求效率的因素主要是三个方面，分别是网络、cpu、内存。在网络层面，Redis采用多路复用的设计，提升了并发处理的连接数，不过这个阶段，Server端的所有IO操作，都是由同一个主线程处理的这个时候IO的瓶颈就会影响到Redis端的整体处理性能。所以从Redis6.0开始，在多路复用及层面增加了多线程的处理，来优化IO处理的能力不过，具体的数据操作仍然是由主线程来处理的，所以我们可以

跳跃表（Skiplist）是Redis中用于实现有序集合（SortedSet）的一种高效数据结构。以下是关于Redis中跳跃表（Skiplist）的关键特性和工作原理的概览：基本概念层级结构：跳跃表通过多层次的链表组成，每一层都是下一层的稀疏视图，顶层最快地遍历整个链表，而底层则是完全连通所有节点的传统链表结构。这样的设计使得查询操作能够快速跳过大量不需要检查的元素。有序集合：每个节点（或称为元素
