Redis的面试问题总结，面试跳槽必备

1.什么是redis? Redis 是一个基于内存的高性能key-value数据库。 2.Reids的特点　 Redis本质上是一个Key-Value类型的内存数据库，很像memcached，整个数据库统统加载在内存当中进行操作，定期通过异步操作把数据库数据flush到硬盘上进行保存。因为是纯内存操作，Redis的性能非常出色，每秒可以处理超过 10万次读写操作，是已知性能最快的Key-Value DB。 Redis的出色之处不仅仅是性能，Redis最大的魅力是支持保存多种数据结构，此外单个value的最大限制是1GB，不像 memcached只能保存1MB的数据，因此Redis可以用来实现很多有用的功能，比方说用他的List来做FIFO双向链表，实现一个轻量级的高性 能消息队列服务，用他的Set可以做高性能的tag系统等等。另外Redis也可以对存入的Key-Value设置expire时间，因此也可以被当作一 个功能加强版的memcached来用。 Redis的主要缺点是数据库容量受到物理内存的限制，不能用作海量数据的高性能读写，因此Redis适合的场景主要局限在较小数据量的高性能操作和运算上。 3.使用redis有哪些好处？ 　 (1) 速度快，因为数据存在内存中，类似于HashMap，HashMap的优势就是查找和操作的时间复杂度都是O(1) (2) 支持丰富数据类型
