A simple heroku app that demonstrates using Kafka in Go. 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 apps:create your-cool-app-name $ heroku addons:create heroku-kafka:basic-0
Create the sample topic. By default, the topic will have 8 partitions:
$ heroku kafka:topics:create messages
Deploy to Heroku and open the app:
$ git push heroku master $ heroku open
