About this book
I wrote the 2nd edition of Kafka Streams in Action to teach you how to build event streaming applications in Kafka Streams and include other components of the Kafka ecosystem, Producer and Consumer clients, Connect, and Schema Registry. I took this approach because for your event-streaming application to be as effective as possible, you’ll need not just Kafka Streams but other essential tools. My approach to writing this book is a pair-programming perspective; I imagine myself sitting next to you as you write the code and learn the API. You’ll learn about the Kafka broker and how the producer and consumer clients work. Then, you’ll see how to manage schemas, their role with Schema Registry, and how Kafka Connect bridges external components and Kafka. From there, you’ll dive into Kafka Streams, first building a simple application, then adding more complexity as you dig deeper into Kafka Streams API. You’ll also learn about ksqlDB, testing, and, finally, integrating Kafka with the popular Spring framework.
