Backburner configuration is taken directly from https://github.com/nesquena/backburner without much changes

Notes

When testing socket connection in random_job.rb, make sure your port is open (this example uses port 3306)

How to test

To insert job into queue:

$ ruby main.rb

To execute the job:

$ ruby worker.rb

DO NOT forget, if you have any changes in random_job.rb then you need to restart your worker.rb
