Reasoning about the performance of a system is a rather tedious and complex task. A microscopic approach would suggest that you construct a model that factors in various components, such as the load and utilization of resources like CPU and I/O when certain code paths are executed. This can get complicated very quickly. Looking at the system's performance as a whole oftentimes suffices to achieve a general understanding of its behavior. Therefore, we propose to follow a pragmatic approach by looking at the system from a macroscopic perspective.

We're looking back on an exciting and insightful JavaLand 2024! My colleague Boris Fresow and I had the pleasure of leading an introductory workshop on Apache Kafka for Java Developers. To share our knowledge further, we are now making the materials from our 1-day workshop available to all interested parties.

Version 3.6.0 of Kafka for JUnit has been released. It increases all Kafka dependencies to 3.6.1.
