Kafka Streams 101 - Getting Started with Kafka Streams

What the course introduces

This is an introductory course on Kafka Streams, the library for processing data that already lives in Kafka. It explains what the library does, how the Streams API is organised, and how the pieces fit into an architecture.

The core idea

The key concept is the stream topology, the graph of processing steps that data passes through. Once that idea is clear, the rest of the API reads as a set of building blocks you assemble into a pipeline.

Who it is for

Developers who already know basic Kafka concepts and want to move from producing and consuming messages to transforming them will find it a logical next step. The description is short, so expect the lessons to cover the getting-started material rather than advanced stateful processing.
