README

A simple Priority Queue Driver for your Laravel Applications to serve your priority messages and makes users happy 🔋.

With the famous Repository Pattern of Laravel, Priority Queue Driver is easily get injected into Laravel's Lifecycle without any hassle/hurdle.

We can use built-in artisan command php artisan queue:work 😎.

Supports

• Laravel 11 (supports by default)
• Laravel 10 (supports until Laravel drops the bug fixes at August 6th, 2024)
• PHP 8.2 & 8.3
• Any database that Laravel supported.

Architecture Diagram

Why Priority Queue Driver use Database?

• Everybody knows Database (MySQL, PgSQL, etc) 👀.
• Easy and simple to implement ❤️.
• Utilize the ORDER BY and INDEX for fast queue msgs pop process. Faster than any other stuff 🔥.
• Highest visibility (you can view the jobs and their data in DB) ⭐️.
• Highest flexibility (you can change the weight directly in DB to unblock important msgs) 💰.
• No extra tool involved. Just Laravel 🥰.

Install Laravel Priority Queue

composer require shipsaas/laravel-priority-queue

One-Time Setup

Export and run the migration (one-time). We don't load migration by default just in case you want to customize the migration schema 😎.

php artisan vendor:publish --tag=priority-queue-migrations
php artisan migrate

Open config/queue.php and add this to the connections array:

'connections' => [
    // ... a lot of connections above
    // then our lovely guy here
    'database-priority' => [
        'driver' => 'database-priority',
        'connection' => 'mysql',
        'table' => 'priority_jobs',
        'queue' => 'default',
        'retry_after' => 90,
        'after_commit' => false, // or true, depends on your need
    ],
],

Scale/Reliability Consideration

It is recommended to use a different database connection (eg mysql_secondary) to avoid the worker processes ramming your primary database.

Usage

The Job Weight

The default job weight is 500.

You can define a hardcoded weight for your job by using the $jobWeight property.

class SendEmail implements ShouldQueue
{
    public int $jobWeight = 500;
}

Or if you want to calculate the job weight on runtime, you can use the UseJobPrioritization trait:

use ShipSaasPriorityQueue\Traits\UseJobPrioritization;

class SendEmail implements ShouldQueue
{
    use UseJobPrioritization;
    
    public function getJobWeight() : int
    {
        return $this->user->isUsingProPlan()
            ? 1000
            : 500;
    }
}

Dispatch the Queue

You can use the normal Dispatcher or Queue Facade,... to dispatch the Queue Msgs

As primary queue

QUEUE_CONNECTION=database-priority

And you're ready to roll.

As secondary queue

Specify the database-priority connection when dispatching a queue msg.

// use Dispatcher
SendEmail::dispatch($user, $emailContent)
    ->onConnection('database-priority');

// use Queue Facade
use Illuminate\Support\Facades\Queue;

Queue::connection('database-priority')
    ->push(new SendEmail($user, $emailContent));

I get that you guys might don't want to explicitly put the connection name. Alternatively, you can do this:

class SendEmail implements ShouldQueue
{
    // first option
    public $connection = 'database-priority';
    
    public function __construct()
    {
        // second option
        $this->onConnection('database-priority');
    }
}

Run The Queue Worker

Nothing different from the Laravel Documentation 😎. Just need to include the database-priority driver.

php artisan queue:work database-priority

# Extra win, priority on topic
php artisan queue:work database-priority --queue=custom

Testing

Run composer test 😆

Available Tests:

• Unit Testing
• Integration Testing against MySQL and queue:work command
