This redis queue driver works just like the standard Laravel redis queue driver, however, it prevents the same job from being queued multiple times.
REQUIREMENTS
Needs PHP >= 7.1 to be installed.
Requires illuminate/redis and illuminate/queue, both "~5.7"
INSTALLATION
Require via Composer
composer require mlntn/laravel-unique-queue
Configure
Create a new connection in config/queue.php
return [
// ...
'connections' => [
'my_unique_name' => [
'driver' => 'unique',
'connection' => 'default',
'queue' => env('UNIQUE_QUEUE_NAME', 'give-me-a-name'),
'retry_after' => 90,
],
//...
]
];
IMPLEMENTATION
Implement a uniquely-queueable job
Your job should use the UniquelyQueueable trait:
<?php
namespace App\Jobs;
use Illuminate\Bus\Queueable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Foundation\Bus\Dispatchable;
use Mlntn\Queue\Traits\UniquelyQueueable;
class MyUniqueJob implements ShouldQueue {
use Dispatchable, InteractsWithQueue, Queueable, UniquelyQueueable, SerializesModels;
/* ... */
}
If the connection is not the default, you will need to specify the connection when dispatching the job:
dispatch(new UniqueJob)->onConnection('my_unique_name');
Implement a unique-queueable event
Since an Event simply encapsulates a Job, the event class should also use the UniquelyQueueable trait:
<?php
namespace App\Events;
use Illuminate\Queue\SerializesModels;
use Mlntn\Queue\Traits\UniquelyQueueable;
class MyEvent {
public function __construct($entityId)
{
$this->entityId;
}
public function getUniqueIdentifier()
{
return $this->entityId;
}
}
Dispatch event:
event(new MyEvent(123));
To specify the queue, the listener has to provide the connection name
<?php
namespace App\Listeners;
class MyListener {
public $connection = env('UNIQUE_QUEUE_NAME');
// use delay if you need
public $delay = 10;
public function handle(MyEvent $event) {
// what ever you need
}
}
Using Lumen
Lumen handles binding slightly different. Use LumenQueueServiceProvider to enable unique queueing in Lumen.
Register service provider in app.php:
$app->register(Mlntn\Providers\LumenQueueServiceProvider::class);
Using Horizon
Set up a worker configuration:
'worker_name' => [
'connection' => 'my_unique_name',
'queue' => ['default'],
'balance' => 'auto',
'processes' => 16,
'tries' => 3,
],
Run Queue Worker
The unique queue behavior acts internally. Run queue worker as known using artisan (via cli, supervisor or another method). For more detailed information head over to https://github.com/illuminate/queue Specify the connection name used in config/queue.php
php artisan queue:work my_unique_name
