To sum up;

delay() – Introduces a delay before processing the job in the queue, allowing you to schedule the job to run after a set amount of time.

$timeout – Specifies how long (in seconds) the job has to run before it is marked as failed if it exceeds this time.

$tries – Defines the maximum number of times the job will be retried if it fails.

retryUntil() – Determines how long (in time) the system should keep retrying the job before marking it as failed. Once this time limit is reached, no further retries will be attempted.

$backoff – Specifies the wait time between each retry attempt after a job fails. Running n independent php artisan queue:work commands means having n separate workers concurrently processing tasks.

php artisan queue:work --queue=queue1,queue2,default – Defines the priority order of the queues, meaning jobs from queue1 will be processed first, followed by queue2, and then the default queue.

The ->onQueue() method allows you to assign a specific name to the queue where the job should be placed
