In the first half of this JavaWorld introduction to Apache Kafka, you developed a couple of small-scale producer/consumer applications using Kafka. From these exercises you should be familiar with the basics of the Apache Kafka messaging system. In this second half, you’ll learn how to use partitions to distribute load and scale your application horizontally, handling up to millions of messages per day. You’ll also learn how Kafka uses message offsets to track and manage complex message processing, and how to protect your Apache Kafka messaging system against failure should a consumer go down. We’ll develop the example application from Part 1 for both publish-subscribe and point-to-point use cases.
