Kafka Streams in Action: Event-driven applications and microservices

Detailed Summary of the Book

Kafka Streams in Action guides software developers through the intricate details of creating event-driven applications with Apache Kafka's Stream Processing API. It takes an absolutely hands-on approach, starting with the basic concepts and gradually heading towards the development of complex microservices. This book assumes a base-level understanding of Java and builds upon it, teaching you how to manage data flow and handle asynchronous processing efficiently.

The book begins with an extensive overview of the fundamental components of Kafka Streams, such as streams, state stores, and processing topologies. You will learn how to create stream processing applications and explore the nuances of handling data records persistently. As the chapters unfold, you delve into concepts like windowed joins, stateful transformations, and the management of processor state.

The practical examples provided throughout the book help reinforce learning by applying those concepts in a real-world setting. You will uncover strategic methods for integrating microservices and discover smarter ways to deploy applications in distributed environments, ensuring robustness and flexibility. It lays a firm foundation for rethinking how applications can be developed in a more data-centric and reactive way.
