PHP 操作 Beanstalkd 方法及参数注释
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*Beanstalkd安装

Pheanstalk操作
连接Beanstalkd
<?php
require __DIR__ . '/vendor/autoload.php';
use Pheanstalk\Pheanstalk;
/**
* 实例化beanstalk
* 参数依次为：ip地址 端口号默认11300 连接超时时间 是否长连接
*/

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'); 相关推荐
