一. 发布订阅

#订阅scribe

127.0.0.1:6379> SUBSCRIBE "channel_1"

Reading messages... (press Ctrl-C to quit)

1) "subscribe"

2) "channel_1"

3) (integer) 1

1) "message"

2) "channel_1"

3) "haha"

1) "message"

2) "channel_1"

3) "hello world"

#发布消息publish

127.0.0.1:6379> publish "channel_1" haha

(integer) 1

127.0.0.1:6379> publish "channel_1" "hello world"

(integer) 1

二. 模拟队列

1. 普通队列 : 对list进行lpush , rpop
2. 优先级队列 :
   
   brpop list1 list2 list3 timeout // 先从list1取,list1没有数据了再从list2取

三. pipline管道

1. redis的管道相当于把多条命令批处理, 使原来多条命令需要多次连接服务器转为多条命令连接一次服务器
2. pipline在命令行下没有，jedis有

/** pipline */

public void test3(){

    Pipeline pipelined = jedis.pipelined();

    for (int i = 0; i < 100; i++) {

        pipelined.set("str"+i,i+"");

    }

    pipelined.sync();  // 提交管道

}
