前言:相对来说我们是比较深度使用redis的,在推荐瀑布流和排行榜等好多的场景我们主要是用的是SortedSet,今天来说一说SortedSet 一、基本的用法 插入数据,常用的有ZADD和ZINCRBY 使用方法Long zadd(byte[] key, double score, byte[] member)插入数据,比我们的推荐场景中,根据用户的行为数据,推荐出来的数据会存放到...
其实只需稍微改造下链表,就能支持类似“二分”的搜索算法,即跳表(Skip list),支持快速的新增、删除、搜索操作。 Redis中的有序集合(Sorted Set)就是用跳表实现的。我们知道红黑树也能实现快速的插入、删除和查找操作。那Redis 为何不选择红黑树来实现呢? 跳表的意义究竟在于何处? 单链表即使存储的数据有序,若搜...
