This article mainly introduces the methods and parameter comments about operating Beanstalkd in PHP. It has certain reference value. Now I share it with everyone. Friends in need can refer to it
Beanstalk is a high-performance, lightweight distributed memory queue system. It was originally designed to reduce the page access of high-volume web application systems by asynchronously executing time-consuming tasks in the background. Delay, supported the Facebook Causes application with 9.5 million users.
Later open sourced, PostRank is now deployed and used on a large scale, processing millions of tasks every day. Beanstalkd is a typical Memcached-like design. The protocol and usage are the same, so users who have used memcached will feel that Beanstalkd looks familiar.
job typical life cycle
put reserve delete -----> [READY] ---------> [RESERVED] --------> *poof*
job possible state migration
put with delay release with delay
----------------> [DELAYED] <------------.

Specify the pipeline to be used
$tube = $pheanstalk->useTube('default');
Insert data into the pipe
$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
);Or:

Listening pipe
$tube = $pheanstalk->watch('user');
Remove pipes that do not need to be monitored
$tube = $pheanstalk->watch('user')->ignore('default');
Listen to the pipe in a blocked manner
$job = $pheanstalk->watch('user')->reserve(4); //堵塞时间为4秒
List all monitored pipes
$pheanstalk->listTubesWatched();
watch reserve method
$pheanstalk->reserveFromTube('default')
Delete the current task
$job = $pheanstalk->watch('default')->reserve(); $pheanstalk->delete($job);
Reset the current task Put it into the pipe
$job = $pheanstalk->watch('default')->reserve(); $pheanstalk->release($job);
to extend the life of the task (when the time to process the task is less than the current task execution time)
$job = $pheanstalk->watch('default')->reserve(); $pheanstalk->touch($job); //TODO
Reserve the task
$job = $pheanstalk->watch('default')->reserve(); $pheanstalk->bury($job);
Release the reserved task (change to reday status)
$job = $pheanstalk->peekBuried('default'); $pheanstalk->kickJob($job);
Release reserved tasks in batches
$pheanstalk->userTube('default')->kick(999); //将id小于999的预留任务全部释放
Read the currently ready tasks (ready)
$job = $pheanstalk->peekReady('default');
Read the task currently in delayed state (delayed)
$job = $pheanstalk->peekDelayed('default');
Set delay for pipeline
$pheanstalk->pauseTube('default', 100); //设置100秒延迟
Cancel the delay on the pipeline
$pheanstalk->resumeTube('default');
