Beanstalkd介紹

什麼是Beanstalkd

Beanstalk,一個高效能、輕量級的分布式記憶體隊列系統,最初設計的目的是想通過後台非同步執行耗時的任務來降低高容量Web應用系統的頁面訪問延遲,支援過有9.5 million使用者的Facebook Causes應用。
後來開源,現在有PostRank大規模部署和使用,每天處理百萬級任務。Beanstalkd是典型的類Memcached設計,協議和使用方式都是同樣的風格,所以使用過memcached的使用者會覺得Beanstalkd似曾相識。

Beanstalkd運行流程

job典型的生命週期

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

job可能的狀態遷移

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

Pheanstalk\Response\ArrayResponse Object(    [_name:Pheanstalk\Response\ArrayResponse:private] => OK    [storage:ArrayObject:private] => Array        (            [id] => 1 //任務job ID            [tube] => test //所處管道            [state] => reserved //目前狀態            [pri] => 1024 //任務優先順序(預設1024)            [age] => 469 //任務存活時間(秒)            [delay] => 0 //任務延遲時間(秒)            [ttr] => 60 //任務執行時間            [time-left] => 59 //任務在reserve狀態維持的秒數            [file] => 0 // binlog-4 預設-0            [reserves] => 2 //總共reserve次數            [timeouts] => 0 //任務逾時次數            [releases] => 0 //重設任務次數            [buries] => 0 //預留次數            [kicks] => 0 //釋放預留任務次數        ))

查看任務的詳細資料(通過ID)

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

Beanstalkd生產者方法

指定需要使用的管道

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

向管道插入資料

$tube = $pheanstalk->useTube('default');$put = $tube->put(    'hello, beanstalk', // 任務內容    1024, // 任務的優先順序    10,  // 不等待直接放到ready隊列中    60 // 處理任務的時間);

或者:

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

Beanstalkd消費者方法

監聽管道

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

去除不需要監聽的管道

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

以堵塞的方式監聽管道

$job =  $pheanstalk->watch('user')->reserve(4); //堵塞時間為4秒

列出所有已經監聽的管道

$pheanstalk->listTubesWatched();

watch + reserve 方法

$pheanstalk->reserveFromTube('default')

刪除當前任務

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

將當前任務重新放入管道

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

為任務續命(當處理任務的時間小於當前任務執行時間時)

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

將任務預留

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

將預留任務釋放(變為reday狀態)

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

批量將預留任務釋放

$pheanstalk->userTube('default')->kick(999); //將id小於999的預留任務全部釋放

讀取當前準備就緒的任務(ready)

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

讀取當前處於延遲狀態的任務(delayed)

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

對管道設定延遲

$pheanstalk->pauseTube('default', 100); //設定100秒延遲

取消對管道的延遲

$pheanstalk->resumeTube('default');
