active_job_lock

https://github.com/dferrazm/active_job_lock

An ActiveJob plugin. Adds locking, with optional timeout/deadlock handling. Using a `lock_timeout` allows you to re-acquire the lock should your job fail, crash, or is otherwise unable to relase the lock. i.e. Your server unexpectedly looses power. Very handy for jobs that are recurring or may be retried.
