README

Yii2 Queue Extension

An extension for running tasks asyncronously via queues.

It supported queues based on DB, Redis, RabbitMQ, Beanstalk and Gearman.

Documentation is at docs/guide/README.md.

Installation

The preferred way to install this extension is through composer.

Either run

php composer.phar require --prefer-dist yiisoft/yii2-queue

or add

"yiisoft/yii2-queue": "~2.0.0"

to the require section of your composer.json file.

Basic Usage

Each task which is sent to queue should be defined as a separate class. For example, if you need to download and save a file the class may look like the following:

class DownloadJob extends BaseObject implements \yii\queue\JobInterface
{
    public $url;
    public $file;
    
    public function execute($queue)
    {
        file_put_contents($this->file, file_get_contents($this->url));
    }
}

Here's how to send a task into queue:

Yii::$app->queue->push(new DownloadJob([
    'url' => 'http://example.com/image.jpg',
    'file' => '/tmp/image.jpg',
]));

Pushes job into queue that run after 5 min:

Yii::$app->queue->delay(5 * 60)->push(new DownloadJob([
    'url' => 'http://example.com/image.jpg',
    'file' => '/tmp/image.jpg',
]));

The exact way task is executed depends on the driver used. The most part of drivers can be run using console commands, which the component registers in your application.

Command that obtains and executes tasks in a loop until queue is empty:

yii queue/run

Command launches a daemon which infinitely queries the queue:

yii queue/listen

See documentation for more details about driver console commands and their options.

The component has ability to track status of a job which was pushed into queue.

// Push a job into queue and get message ID.
$id = Yii::$app->queue->push(new SomeJob());

// The job is waiting for execute.
Yii::$app->queue->isWaiting($id);

// Worker gets the job from queue, and executing it.
Yii::$app->queue->isReserved($id);

// Worker has executed the job.
Yii::$app->queue->isDone($id);
