Apache Kafka Series – Kafka Streams for Data Processing

• Write four Kafka Streams application in Java 8
• Configure Kafka Streams to use Exactly Once Semantics
• Scale Kafka Streams applications
• Program with the High Level DSL of Kafka Streams
• Build and package your application
• Write tests for your Kafka Streams Topology
• And so much more! 

Section outline:

1. Kafka Streams – First Look: Let’s get Kafka started and run your first Kafka Streams application, WordCount
2. End-to-End Kafka Streams Application : Write the code for the WordCount, bring in the dependencies, build and package your application, and learn how to scale it. This is a complete end to end example
3. KStream and KTable Simple Operations: Learn all the stateless operations available for the KStream and KTable API
4. Practice Exercise – Favourite Colour: Practice your newly acquired skills by writing your own Kafka Streams application, Favourite Colour. It will be challenging! Includes a Scala version of the example
5. KStream and KTable Advanced Operations: Learn all the stateful operations available for the KStream and KTable API
6. Exactly Once Semantics – Theory: Learn what EOS (Exactly Once Semantics) is, how Kafka 0.11 enables it, and how to activate them in Kafka Streams
7. Exactly Once – Practice Exercise – Bank Balance: Practice your newly acquired knowledge by writing your own Kafka Streams Exactly Once application, to compute a running Bank Balance for your customers
8. Testing your Kafka Streams Application: Learn how to test the WordCount Kafka Streams Topology with Kafka Streams v1.1.0
