I am performing some job with Resque-worker (5 workers). Now, when this job is completed/done I want to trigger another worker which processes the data previous worker stored in
I'm not sure if this is of any help, but have you had a look at the resque-status gem?
That way you can track a given jobs' status, to see when it is completed. But I'm affraid there are no auto-trigger functionality, to start new workers.
