Tutorial

Take the IBM Event Streams Java app coding challenge

In this tutorial, you'll actually build a small application. First, however, you will first run a small binary application. This application will produce some records to a topic. Then, your challenge is to write a consumer application that will consume records from the topic and will recover the secret message that is put inside one of the records.
