Beanstalkd的使用(Golang)

          最近需要引入一种新的消息队列，这个队列最好有专业、简单、消息不丢失等特性，但又不会引入过多的复杂性，
 特别是在目前单枪匹马的情况下。然后发现Beanstalkd看起来是我所需要的.
        Beanstalkd 支持任务优先级 (priority), 延时 (delay), 超时重发 (time-to-run) 和预留 (buried), 
 同时支持binlog.最后速度还可以。
 看了下源码,c语言代码量小而清晰.作者从07年维护到14年,Star也很高,质量应当是有保障的。
 队列作者提供了Go客户端,从作者项目列表中可以看到已经写了不少Go相关的东西,看来Go很受后台开发的欢迎。

      写了个调用例子如下.

 可用beanstool来查看队列状态

 

也可以参考我写下面两段，来查。

ar, er := c.ListTubes()if er != nil {fmt.Println("[Example]  er:", er)} else {for i, v := range ar {fmt.Println("[Example] ListTubes  i:", i, " v:", v)c.Tube.Name = vid, body, err := c.Reserve(5 * time.Second)if err != nil {fmt.Println("[Example] err:", err, " name:", c.Tube.Name)continue} else {fmt.Println("[Example] job:", id)fmt.Println("[Example] body:", string(body))}}}func tubeStatus(c *beanstalk.Conn) {fmt.Println("[tubeStatus]/////////////////////////")fmt.Println("Tube(", c.Tube.Name, ") Stats:")m, er := c.Tube.Stats()if er != nil {fmt.Println("[tubeStatus] err:", er)} else {for k, v := range m {fmt.Println(k, " : ", v)}}fmt.Println("[tubeStatus]/////////////////////////")}

  从测试看,Beanstalkd 足以满足我现在的需求了.
