Since kaf v0.1.35 it is now possible to interact with Azure EventHub. Kaf is a modern CLI to interact with Kafka, i.e. producing data, consuming, or viewing topic and Consumer Group information. Now having first-class support for EventHub makes EventHub much more accessible than before. In the following Example i’ll show how to set up kaf for your EventHub. It’s very simple.

How does it work? On a very high level, a basic runtime (called SubstrateVM) is compiled into the binary, as well as the actual application. Sounds a little like Go, which also includes a small runtime for e.g. garbage collection. In this article, I’ll show how to build a small sample restful webservice with GraalVM native compilation. The sample application is written in Java. Why would somebody even be interested in native compilation of a JVM application? On my day job at E.ON i sadly still have to work a lot with Java applications. Our tech stack is completely cloud native - we run almost everything on Kubernetes. Our applications are “typical” 12 Factor applications. In such a dockerized environment, i think there are three major reasons why native compilation would be interesting. Read more
