队列工作延迟4小时

Question

I have a mission-critical queue in laravel 5.4 which is powerd by Redis and 8 workers on supervisor.

In this queue, I have to make delayed jobs with a delay about 4 hours like this:

        $job = (new VerifyAndOrderJob($books))
            ->onQueue('orders')
            ->delay(\Carbon::now()->addHours(4));


        dispatch($job);

Now since Laravel queues are based on FIFO, If I have thousands of delayed jobs like this in the queue everyday and I wanted to push a same job but without any delay, is it need to wait till other delayed jobs to be processed or this will be fired instantly?
