Write Notifications ⚙️ Demystifying Laravel Jobs & Queues: Best Practices for Scalable Task Processing Sandeeppant Sandeeppant 3 min read · May 28, 2025

While building your web application, you may have some tasks, such as parsing and storing an uploaded CSV file, sending emails, image processing, API calls, etc. that take too long to perform during a typical web request. Thankfully, Laravel allows you to easily create queued jobs that may be processed in the background. By moving time intensive tasks to a queue, application can respond to web requests with blazing speed and provide a better user experience to customers. #Creating Jobs

By default, all of the queueable jobs for your application are stored in the app/Jobs directory. If the app/Jobs directory doesn't exist, it will be created when you run the make:job Artisan command:

php artisan make:job SendEmail

This creates a job class in app/Jobs/SendEmail.php with a handle() method, where you write the job logic.

use App\Mail\WelcomeMail; use Illuminate\Support\Facades\Mail;

public function handle() {

  Mail::to($this->user->email)->send(new WelcomeMail($this->user));

}

#Dispatching Jobs

To queue a job, you dispatch it like so:

SendEmail::dispatch($user);

You can delay it too:

SendEmail::dispatch($user)→delay(now()→addMinutes(10));

⚙️ Queue Configuration

Laravel supports different queue drivers out of the box, like: Press enter or click to view image in full size

Set your preferred driver in .env:

For high-throughput apps, Redis is often the go-to choice.

QUEUE_CONNECTION=redis

Configure Redis queues in config/queue.php, and ensure you have Redis installed or a cloud provider configured.

Then create the jobs table:

php artisan queue:table php artisan migrate

🧾 Running the Queue Worker

php artisan queue:work

You can also run it as a daemon with:

php artisan queue:work –daemon

#Job Chaining:

Laravel supports job chaining — a powerful way to run multiple jobs in sequence.

Bus::chain([

  new ProcessPodcast($podcast),
  new OptimizePodcast($podcast),
  new ReleasePodcast($podcast),

])→dispatch();

  If any job in the chain fails, the remaining jobs won’t be executed.
  Combine with catch() to handle failure:

Bus::chain([…])

1. >catch(function (Throwable $e) {

Handle chain failure })→dispatch(); #Job Batching: Batching allows you to dispatch a group of jobs together and track their collective progress. Bus::batch([ new ResizeImage($image), new ApplyWatermark($image), new UploadToCDN($image), ])→then(function (Batch $batch) { All jobs completed })→catch(function (Batch $batch, Throwable $e) {

  // Handle failed job

})→finally(function (Batch $batch) {

  // After all jobs (success or failure)

})→dispatch();

To use batching, ensure Queue::batch()configure the database tables with:

php artisan queue:batches-table php artisan migrate

#Job Middleware

Middleware can apply behaviors before or after the job executes:

  Rate limiting
  Preventing duplicates
  Locking

Example — prevent overlapping:

use Illuminate\Queue\Middleware\WithoutOverlapping;

public function middleware() {

  return [new WithoutOverlapping($this->user->id)];

}

You can also use:

  ThrottlesExceptions
  RateLimited
  Custom middleware for retry/backoff control.

#Retry Strategies and Backoff

Each job can define how long to wait before retrying:

public function backoff() {

  return [10, 30, 60]; // retry after 10s, then 30s, then 60s

}

You can also control maximum retries:

public $tries = 5; public $maxExceptions = 3;

To globally set retry strategy, use config/queue.php. #Job Failures, Timeouts, and Alerts

Jobs may fail due to:

  External API issues
  Timeouts
  Exceptions

You can handle job failure gracefully with failed():

public function failed(Throwable $exception) {

  Log::error("Job failed: " . $exception->getMessage());

}

Timeouts:

public $timeout = 120; seconds To alert via Slack or email, use Notification classes in failed(). #Scheduling Queued Jobs Queued jobs can also be scheduled via Laravel’s task scheduler: $schedule→job(new CleanUpTempFiles)→daily(); Press enter or click to view image in full size Conclusion Laravel’s job and queue system is not just about sending emails — it’s a gateway to building resilient, scalable, event-driven architectures. With advanced techniques like batching, chaining, middleware, and Horizon monitoring, you can turn your Laravel app into a finely-tuned asynchronous machine.
