redis相传性能不错,不仅结合了key value数据库的优点,又有满足一些必要的关系型数据库的功能。 我们有个产品最近想为每个用户出排行榜,APP,SNS产品常见功能，每个用户与好友做排行榜排序......无聊又必备功能。 还没测试redis性能。但功能是可以实现的。还挺不错的....稍后会测试测试性能,和PHP的API 要是不错....那可真是神物啊。 做个示例: [root@xpdmediainc04 redis-1.02]# ./redis-cli sadd tom:friend:list 123 #tom的好友列表 里面是好友的uid 1 [root@xpdmediainc04 redis-1.02]# ./redis-cli sadd tom:friend:list 456 1 [root@xpdmediainc04 redis-1.02]# ./redis-cli sadd tom:friend:list 789 1 [root@xpdmediainc04 redis-1.02]# ./redis-cli sadd tom:friend:list 101 1 [root@xpdmediainc04 redis-1.02]# ./redis-cli set uid:sort:123 1000 #uid对应的成绩 OK [root@xpdmediainc04 redis-1.02]# ./redis-cli set uid:sort:456 6000 OK [root@xpdmediainc04 redis-1.02]# ./redis-cli set uid:sort:789 100 OK [root@xpdmediainc04 redis-1.02]# ./redis-cli set uid:sort:101 5999 OK [root@xpdmediainc04 redis-1.02]# ./redis-cli set uid:123 "{'uid':123,'name':'lucy'}" #增加uid对应好友信息 OK [root@xpdmediainc04 redis-1.02]# ./redis-cli set uid:456 "{'uid':456,'name':'jack'}" OK [root@xpdmediainc04 redis-1.02]# ./redis-cli set uid:789 "{'uid':789,'name':'marry'}" OK [root@xpdmediainc04 redis-1.02]# ./redis-cli set uid:101 "{'uid':101,'name':'icej'}" OK [root@xpdmediainc04 redis-1.02]# ./redis-cli sort tom:friend:list by uid:sort:* get uid:* #从好友列表中获得id与uid:sort字段匹配后排序,并根据排序后的顺序，用key在uid表获得信息 1. {'uid':789,'name':'marry'} 2. {'uid':123,'name':'lucy'} 3. {'uid':101,'name':'icej'} 4. {'uid':456,'name':'jack'} [root@xpdmediainc04 redis-1.02]# ./redis-cli sort tom:friend:list by uid:sort:* get uid:* get uid:sort:* 1. {'uid':789,'name':'marry'} 2. 100 3. {'uid':123,'name':'lucy'} 4. 1000 5. {'uid':101,'name':'icej'} 6. 5999 7. {'uid':456,'name':'jack'} 8. 6000
