Golang Workers / Job Queue

A running example of the code from:

• http://marcio.io/2015/07/handling-1-million-requests-per-minute-with-golang
• http://nesv.github.io/golang/2014/02/25/worker-queues-in-go.html

This gist creates a working example from blog post, and a alternate example using simple worker pool.

TLDR: if you want simple and controlled concurrency use a worker pool.

# 1. A recent version of Ruby is required 
# 2. Ensure the required gems are installed with `gem install rspec json rspec-command`
# 3. Run this from the command line with rspec sampletokenSpec.rb

# Optionally output the test results with -f [p|d|h] for required views of the test results.

# For debugging I added a clear action to the contract which clears everything in the tables
