There is a case where I need to run 100 jobs simultaneously . I did my R&D and I came to a point that i need to create multiple queues to run multiple jobs at a time. But I have dynamic number of job count which I need to execute in a given time.
Solution #1 (Create multiple job queues)
php artisan queue:work --queue=myJobQueue & php artisan queue:work --queue=myJobQueue1 & php artisan queue:work --queue=myJobQueue2
Can anyone please suggest the best approach to do this task ?

I know you can stop all workers in Laravel using queue:restart. But I'm looking for a way to stop all workers working on a specific queue. Something like this:
php artisan queue:restart --queue=my_queue
As far as I read the documentation,
php artisan queue:clear redis --queue=emails
is only available for The SQS, Redis, and database queue drivers.
But this command is clearing, not stopping.
I have been searching a lot for a solution until I just gave up...
I want to run php artisan queue:work --stop-when-empty command every minute in Laravel task scheduler.
I have tried this
$schedule->command('queue:work --stop-when-empty')->everyMinute()->runInBackground();
but that doesn't seem to work at all...
You are not supposed to run the queue in the scheduler.
The queue should always be up and running (using a process manager, like Supervisor) and pick jobs when they are dispatched (dispatched in a scheduled task or somewhere else, it doesn't matter).
Here is the documentation on this topic: https://laravel.com/docs/8.x/queues#supervisor-configuration
I need to convert/resize uploaded images using Laravel so they are available during the next seconds or minute or so...
I was wondering, to have less pressure on the server, is it better to do this using Laravel Schedules or Queues
If Queues is the way to go, how to dispatch? (delayed?)
If you are expecting multiple users uploading multiple images concurrently, in that case, I would stick with Queue for this task. Here's a link to Laravel 7.x Queue, they have really good documentation.
Step 1: php artisan queue:table & php artisan migrate. This will create 2 tables: jobs and failed_jobs.
Step 2: Create a Job php artisan make:job ResizeImage. This will create a new file under jobs folder. It's the implements ShouldQueue that's gonna do the magic for you.
Step 3: To make a dispatch call. ResizeImage::dispatch($params);. To delay, add ->delay(now()->addMinutes(10));
Step 4: In your .env file, change QUEUE_CONNECTION=sync to QUEUE_CONNECTION=database. This config will be used by config/queue.php file.
Step 5: Clear config and cache. php artisan config:clear php artisan cache:clear
Things to understand:
When you dispatch a job, a new row will be added to jobs table. Whatever you add to the handle() method in your jobs file will be added to the payload column of the table.
To trigger the queue, you can either add a supervisor to your server or a simple php artisan queue:work will run the jobs.
Please go through the docs, they have really good + deep + better explanation with examples. Cheers!
I'm using redis queue driver in Laravel 6.14. Today I've realized, that when I'm using php artisan queue:work it outputs processed jobs totally randomly. Does anybody come up with the same problem? I thought it outputs all jobs (correctly processed and failed). Thans for any ideas and help.

How to keep Laravel Queue system running on server
(20 answers)
Closed 4 years ago.
I have jobs to send several emails.
In my controller I call the job:
dispatch(new SendStartPatEmail($data));
And record is saved in table jobs.
But to execute the job I have to run php artisan queued:work manually.
How can I do this automatically?
There are lots of different ways, all depending on the environment that you're using. Laravel tends to recommend using Supervisor to monitor your queue workers and keep them running.
Alternatively, you may wish to have your jobs execute immediately, instead of adding them to a queue. You can do this by setting your queue driver to sync, either in your config:
config/queue.php
'default' => env('QUEUE_DRIVER', 'sync'),
or in your .env file (assuming your config is set up as above)
.env
QUEUE_DRIVER=sync

Yes, if you use Linux you can use for example supervisor which will
run php artisan queue:listen (you need to add this command to
supervisor configuration file) and it will make sure all the time this
command is running.
php artisan queue:work is a simple command that listens to a queue and executes some jobs.
What's the whole concept?
You can run this simple command on the background and all jobs in queue will be executed.
But running a process (queue:work) on the background is not always safe.
Why? because there is always the chance that the process may be terminated or stuck because of a memory leak.
In this case laravel recommends the use of a Supervisor .The supervisor is another process working like a service.It is responsible to check whether the process that php artisan queue:work creates, works normally or it should be restarted.
This way php artisan queue:work runs on the background but there is a mechanism (supervisor) which can restart the process in case something goes wrong
There is the dispatch_now( ... ) method for specifying those jobs you want run synchronously.
I don't care for underscores, so I usually create a helper method dispatchNow( ... ) that calls the underscore version.. 😛
