Installation

You can install this package via composer using this command:

composer require pdffiller/laravel-queue-qless

The package will automatically register itself using Laravel auto-discovery.

Setup connection in config/queue.php

    'connections' => [
        // ...
        'qless' => [
            'driver' => 'qless',
            'redis_connection' => 'qless',
            'queue' => 'default',
        ],
        // ...    
    ],

Also you can set Qless queue as default in config/queue.php

    'default' => env('QUEUE_DRIVER', 'qless'),

Redis connection in config/database.php

    'redis' => [

        'client' => 'predis',

        // ...
        'qless' => [
            'host' => env('REDIS_HOST', '127.0.0.1'),
            'password' => env('REDIS_PASSWORD', null),
            'port' => env('REDIS_PORT', 6379),
            'database' => 0,
        ],
        // ...
    ],

And add Laravel Qless service provider to app.php

<?php

return [
    //...
    'providers' => [
        //...
        /**
         * Qless
         */
         LaravelQless\LaravelQlessServiceProvider::class,
    ]
];

Usage

Once you completed the configuration you can use Laravel Queue API. If you used other queue drivers you do not need to change anything else. If you do not know how to use Queue API, please refer to the official Laravel documentation: http://laravel.com/docs/queues

Also you can use additional features.

Topics

Topic help you to put a job to different queues. First, you must to create a subscription. You can use pattern for name of topics. Symbol * - one word, # - few words divided by point .. Examples: first.second.*, *.second.*, #.third.

/**
 * Subscribe
 */

\Queue::subscribe('*.*.test', 'queue1');

\Queue::subscribe('this.*.test', 'queue2');

\Queue::subscribe('this.*.orange', 'queue3');

Than you can put job to all subscribers.

/**
 * Put job to few queues
 */
\Queue::pushToTopic('this.is.test', TestQless::class, ['test' => 'test']);
// Push job to queue1 and queue2, but not to queue3

Custom Handler

Job Handler helps you to create a custom route for jobs.

Custom Handler example:

    class CustomHandler implements JobHandler
    {
        public function perform(BaseJob $job): void
        {
            if ($job->getQueue() === 'queue_name') { // by queue
                (new QueueNameJob)->perform($job);
                return;
            }
            
            if ($job->getData()['option_name'] === 'value') { // by payload
                (new OptionNameJob)->perform($job);
                return;
            }
            
            if (in_array('tag_name', $job->getTags())) { // by tag
                (new TagNameJob)->perform($job);
                return;
            }
            
            // other
            
            $job->perform(); // Default
        }
    }
    

You must add to a service provider.

    public function boot()
    {
        // other code

        $this->app->bind(JobHandler::class, CustomHandler::class);
        
        // other code
    }

Recurring Jobs

Sometimes it's not enough simply to schedule one job, but you want to run jobs regularly. In particular, maybe you have some batch operation that needs to get run once an hour and you don't care what worker runs it. Recurring jobs are specified much like other jobs:

/**
 * Recurring Job
 */
 
\Queue::recur($intervalInSeconds, $jobClass, $data, $queueName); 

Sharding

If you compare Qless sharding with the DB sharding, then they have little in common. Qless gets random write-connection for all jobs. Data reading occurs in a circle from all connections.

Setup redis connections for sharding in config/database.php:

return [
    'redis' => [
        // ...
        'qless' => [ /* ... */ ],
        'connection2' => [ /* ... */ ],
        'connection3' => [ /* ... */ ],
        // ...
    ],
];

Then set the shards via redis_connection key in config/queue.php file:

return [
    'connections' => [
        // ...
        'qless' => [
            // ...
            'redis_connection' => [
                'connection2',
                'connection3',
            ],
            // ...
        ],
        // ...
    ],
];

Testing

You can run the tests with:

vendor/bin/phpunit
