Part of BuzzingPixel's Corbomite project.

This project provides a Queue for adding items to be run by the server in sequence.

Usage

When you require this into a Corbomite project, the CLI commands and dependency injection config will automatically be set up.

Installation

Corbomite Queue needs to add a couple of database tables in order to function. In order to do this, it needs to create some migrations which then need to be run. Run the create-migrations command, which will place migration files in your Corobomite project.

php app queue/create-migrations

After running that command, you'll need to run the migrations:

php app migrate/up

Running the queue

Development environment

In dev, you'll probably just want to run the queue manually. The command to do that is:

php app queue/run

That command runs the next item in your queue.

Production Environments

As of 1.3.0, Corbomite Queue is multiple worker aware. That means you can and should have multiple workers running the queue/run command in a loop (how many workers will depend on how beefy your server environment is and how many resources you want consumed on the queue). The queue tracks which batches are running and which are not running. The next worker will pick up the next task in a batch that does not currently indicate it is running.

An example shell script is provided in this repository for Linux environments. Example Shell Script.

You are encouraged to use Supervisor to set multiple workers to run this script.

Adding to the queue

The Queue API is provided to make things extremely easy to add items to the queue. Note that in the examples below, any class you specify to add to the queue, Corbomite Queue will attempt to get it from the Dependency Injector first so you can use dependency injection if you want to.

<?php
declare(strict_types=1);

use corbomite\di\Di;
use corbomite\queue\QueueApi;

/** @noinspection PhpUnhandledExceptionInspection */
$queueApi = Di::diContainer()->get(QueueApi::class);

$batchModel = $queueApi->makeActionQueueBatchModel([
    'name' => 'this_is_a_test',
    'title' => 'This is a Test',
    'items' => [
        $queueApi->makeActionQueueItemModel([
            'class' => \some\ClassThing::class,
        ]),
        $queueApi->makeActionQueueItemModel([
            'class' => \another\ClassThing::class,
        ]),
        $queueApi->makeActionQueueItemModel([
            'class' => \more\Classes::class,
            'method' => 'someMethod', // If method is not specified, --invoke is assumed
            // Provide anything you want in this array, your method will receive it as an argument
            'context' => [
                'stuff' => 'thing',
            ],
        ]),
    ],
]);

/** @noinspection PhpUnhandledExceptionInspection */
$queueApi->addToQueue($batchModel);
