#region List
/*
* list是一个链表结构,主要功能是push,pop,获取一个范围的所有的值等,操作中key理解为链表名字。
* Redis的list类型其实就是一个每个子元素都是string类型的双向链表。我们可以通过push,pop操作从链表的头部或者尾部添加删除元素,
* 这样list既可以作为栈,又可以作为队列。Redis list的实现为一个双向链表,即可以支持反向查找和遍历,更方便操作,不过带来了部分额外的内存开销,
* Redis内部的很多实现,包括发送缓冲队列等也都是用的这个数据结构

#region Set无序集合

#region SetSorted 有序集合
/*
sorted set 是set的一个升级版本,它在set的基础上增加了一个顺序的属性,这一属性在添加修改.元素的时候可以指定,
* 每次指定后,zset(表示有序集合)会自动重新按新的值调整顺序。可以理解为有列的表,一列存 value,一列存顺序。操作中key理解为zset的名字.
