==== Examples
* :priority - Enqueues the job with the specified priority
* :queue - Enqueues the job on the specified queue
* :wait_until - Enqueues the job at the time specified
* :wait - Enqueues the job with the specified delay in seconds
==== Options
you can ask Active Job to retry performing your job.
with the +rescue_from+ option. When you rescue an exception from your job
Reschedules the job to be re-executed. This is useful in combination
