Beanstalkd介绍

什么是Beanstalkd

Beanstalk,一个高性能、轻量级的分布式内存队列系统,最初设计的目的是想通过后台异步执行耗时的任务来降低高容量Web应用系统的页面访问延迟,支持过有9.5 million用户的Facebook Causes应用。
后来开源,现在有PostRank大规模部署和使用,每天处理百万级任务。Beanstalkd是典型的类Memcached设计,协议和使用方式都是同样的风格,所以使用过memcached的用户会觉得Beanstalkd似曾相识。

Beanstalkd运行流程

job典型的生命周期

   put            reserve               delete
  -----> [READY] ---------> [RESERVED] --------> *poof*

job可能的状态迁移

   put with delay               release with delay
  ----------------> [DELAYED] <------------.
                        |                   |
                 kick   | (time passes)     |
                        |                   |
   put                  v     reserve       |       delete
  -----------------> [READY] ---------> [RESERVED] --------> *poof*
                       ^  ^                |  |
                       |   \  release      |  |
                       |    `-------------'   |
                       |                      |
                       | kick                 |
                       |                      |
                       |       bury           |
                    [BURIED] <---------------'
                       |
                       |  delete
                        `--------> *poof*

        )
)

查看任务的详细信息(通过ID)

$job =  $pheanstalk->peek(1);
$job_stats = $pheanstalk->statsJob($job);

Beanstalkd生产者方法

指定需要使用的管道

$tube = $pheanstalk->useTube('default');

向管道插入数据

$tube = $pheanstalk->useTube('default');
$put = $tube->put(
    'hello, beanstalk', // 任务内容
    1024, // 任务的优先级
    10,  // 不等待直接放到ready队列中
    60 // 处理任务的时间
);

或者:

$pheanstalk->putInTube('default',  'test1', 1024, 10, 60);

Beanstalkd消费者方法

监听管道

$tube =  $pheanstalk->watch('user');

去除不需要监听的管道

$tube =  $pheanstalk->watch('user')->ignore('default');

以堵塞的方式监听管道

$job =  $pheanstalk->watch('user')->reserve(4); //堵塞时间为4秒

列出所有已经监听的管道

$pheanstalk->listTubesWatched();

watch + reserve 方法

$pheanstalk->reserveFromTube('default')

删除当前任务

$job =  $pheanstalk->watch('default')->reserve();
$pheanstalk->delete($job);

将当前任务重新放入管道

$job =  $pheanstalk->watch('default')->reserve();
$pheanstalk->release($job);

为任务续命(当处理任务的时间小于当前任务执行时间时)

$job =  $pheanstalk->watch('default')->reserve();
$pheanstalk->touch($job);
//TODO

将任务预留

$job =  $pheanstalk->watch('default')->reserve();
$pheanstalk->bury($job);

将预留任务释放(变为reday状态)

$job = $pheanstalk->peekBuried('default');
$pheanstalk->kickJob($job);

批量将预留任务释放

$pheanstalk->userTube('default')->kick(999); //将id小于999的预留任务全部释放

读取当前准备就绪的任务(ready)

$job = $pheanstalk->peekReady('default');

读取当前处于延迟状态的任务(delayed)

$job = $pheanstalk->peekDelayed('default');

对管道设置延迟

$pheanstalk->pauseTube('default', 100); //设置100秒延迟

取消对管道的延迟

$pheanstalk->resumeTube('default');
