queue_classic adapter for Active Job
queue_classic provides a simple interface to a PostgreSQL-backed message queue. queue_classic specializes in concurrent locking and minimizing database load while providing a simple, intuitive developer experience. queue_classic assumes that you are already using PostgreSQL in your production environment and that adding another dependency (e.g. redis, beanstalkd, 0mq) is undesirable.

To use queue_classic set the queue_adapter config to
Rails.application.config.active_job.queue_adapter = :queue_classic
QC::Queue object to schedule jobs on.
If you have a custom
QC::Queue subclass you'll need to subclass
ActiveJob::QueueAdapters::QueueClassicAdapter and override the
# File activejob/lib/active_job/queue_adapters/queue_classic_adapter.rb, line 45 def build_queue(queue_name) QC::Queue.new(queue_name) end
