Что такое Laravel Queues?

// Job
class SendEmailJob implements ShouldQueue {
    use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;

    public function __construct(public User $user) {}

    public function handle(Mailer $mailer): void {
        $mailer->send($this->user->email, new WelcomeEmail());
    }

    public function failed(Throwable $e): void {
        Log::error('Email failed', ['user' => $this->user->id]);
    }
}

// Отправка в очередь
SendEmailJob::dispatch($user);
SendEmailJob::dispatch($user)->onQueue('emails')->delay(now()->addMinutes(5));
