Queue Module

Overview

Simple multi driver queue system. This is essentially a port of the Laravel queue system.

Still very much a WIP not for use in production!

Although it would be better to use illuminate/queue directly it has too many dependancies that would replicate silverstripe/framework functionality at this time. By porting the code we can take advantage of SilverStripes command line framework and dependancy injection whilst still having a feature rich and multi backend queue system.

So our thanks go to Taylor Otwell et al for their excellent work on Laravel.

    db:
        driver: 'db'
        queue: 'default'

Usage Overview

Import QueueManager

Import the QueueManager class for ease of use.

use StudioBonito\SilverStripe\Queue\QueueManager;

Push A Job Onto The Queue

Use QueueManager::inst() to get an instance of the QueueManger class and then call the push() method passing in the name of a job handler and an array of data.

QueueManager::inst()->push('SendEmail', array('message' => $message));

Creating A Job Handler

Job handlers are simple classes that contain a run method with $job and $data parameters.

class SendEmail {

    public function run($job, $data)
    {
        // Code for processing job goes here.
    }
}
