废话开篇 相比于其他内存数据库,Redis最大的特点就是拥有丰富的数据结构, 经常被称为Date Structure Server.Redis支持的数据结构包含strings, hashes, lists, sets and sorted sets.可以说能包含的基本都包含了,哈哈. 代码示例 下面列出的是对上述数据结构的操作代码示例,请选择参考. /** * @Title: RedisDemo.java * @Package never.database.redis * @author "Ne…
废话开篇 以前从来没听说过有Redis这么个玩意,无意间看到一位仁兄的博客,才对其有所了解,所以决定对其深入了解下.有不对的地方还请各位指正. Redis介绍 下面是官方的介绍,不喜欢english的直接绕到中文的介绍区域. Redis is an open source, BSD licensed, advanced key-value store. It is often referred to as a data structure server since keys can contai…
废话开篇 Redis的安装是非常简单易操作的,但是配置就有点复杂了,要想得到高性能的Redis数据服务,深入了解下如何配置是很重要的. 配置详解 下面是主要的参数及说明,至于如何配置才能最优,目前还不清楚,因为刚刚迈出了几步而已. daemonize 是否以后台进程运行,默认为no pidfile 如以后台进程运行,则需指定一个pid,默认为/var/run/redis.pid bind 绑定主机IP,默认值为127.0.0.1(注释) port 监听端口,默认为6379 timeout 超时时…

Implement a data structure supporting the following operations: Inc(Key) - Inserts a new key with value 1. Or increments an existing key by 1. Key is guaranteed to be a non-empty string. Dec(Key) - If Key's value is 1, remove it from the data structu…
Design a data structure that supports the following two operations: void addWord(word) bool search(word) search(word) can search a literal word or a regular expression string containing only letters a-z or .. A . means it can represent any one letter…
Design and implement a TwoSum class. It should support the following operations:add and find. add - Add the number to an internal data structure.find - Find if there exists any pair of numbers which sum is equal to the value. For example,add(1); add(…
