In this workshop you will learn how to build scalable Kafka Streams applications with Spring Boot and Spring Kafka. You are introduced to the concepts of Kafka and streaming and get some hands on experience building an application using Kafka Streams components such as kStreams, kTables, filters, branches, and solving interesting challenges with complex joins and aggregates. We have been running a system with Kafka Streams in production successfully. I had a lot of fun building Kafka Streams applications and I would like to share what we have learned in the past year.
