A simple heroku app that demonstrates using Kafka in ruby. This demo app accepts HTTP POST requests and writes them to a topic, and has a simple page that shows the last 10 messages produced to that topic.
You'll need to provision the app.
Install the kafka cli plugin:
$ heroku plugins:install heroku-kafka
Create a heroku app with Kafka attached:
$ heroku create
$ heroku addons:create heroku-kafka:beta-dev
$ heroku kafka:wait
Create the sample topic, by default the topic will have 32 partitions:
$ heroku kafka:create messages
Deploy to Heroku and open the app:
$ git push heroku master
$ heroku open
