Hey,
Does delayed_jobs take signals? I would love to tell DJ to finish processing the current jobs, but stop taking new ones, so I can deploy a new version of the code without abruptly `SIGTERM` stopping the current jobs being processed.

The standard signals do that already.

Hi David,
hm good point: https://github.com/collectiveidea/delayed_job/blob/73bd1b50e719b336b70fcbb8dc4a37ec9b2f6f35/lib/delayed/worker.rb#L159
raise_signal_exceptions is set to :term (most likely the default value). So the idea is to set it to false from preventing the Signal Exception?
My workers are currently deployed to Heroku and I don't want to abruptly terminate them, so my idea is to stop processing then deploy.

Yes, but be aware, Heroku is not very patient. Your process has 30 seconds to gracefully shutdown before it hard kills it.
