heroku-kafka-demo-go

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.

Provisioning

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
