Each section can be either theoretical, or a practice section. 

> Through practice, you will be challenged by writing your own Kafka Streams application. The solutions will be thoroughly explained, and you will learn some tips on how to use Kafka Streams the best way.

> Through theory, you will learn about all the available API, the inner workings of the library, as well as some exciting concepts such as Exactly Once Semantics!

This course is the first and only available Kafka Streams course on the web. Get it now to become a Kafka expert!
