While I’ve never used it personally, I’ve looked at using RabbitMQ for the ActiveJob queue. The current implementation of the SneakersAdapter has a JobWrapper that hard codes the queue it’s running from. Since you can put things on different queues, like I believe the default mailer does, you have no built-in way to run it.
I get that this is a situation that isn’t well supported for Sneakers but there shouldn’t be a broken implementation in Rails itself.
