**Topics**

***Event Driven in the Wild with Kafka***
Tutorials make building event driven applications look easy—just sprinkle some annotations over your code base, and you’re done! But as it turns out, reality can be far trickier.

This talk is for anyone about to embark on building a Java-based Event Driven Architecture, as well as for those who already have and want to compare battle scars.

I’ll start from the ground up—covering how to organize your teams and structure your codebase for an event-driven world, and exploring key patterns and frameworks that apply regardless of the technology stack—before diving into the nitty-gritty details of working with Kafka.

**About Jonas**
Curious software engineer with a focus on all things Java. Currently working for Cymo specializing in event driven and streaming architectures.

***Scared of the ExecutorService? Try JobRunr Jobs instead!***
Is thinking about retryability, observability, and resource control giving you a headache when it comes to Java threading? Why not use JobRunr to let it handle the complexity instead?

In this quick session, we'll touch upon the differences of various approaches to Java threading and how to leverage JobRunr as your robust threading manager instead of whipping up a homebrew solution.

**About Wouter**
Wouter Groeneveld is a software engineer with more than 15 years of experience wrangling with different programming languages and ecosystems, including the JVM. As part of the JobRunr team, he now helps making background job processing easier to grok for developers.

**Additional notes:**

* **This meetup includes food. Please keep your RSVP status up to date so we do not waste any of our food.**
* **Some pictures might be made. If you feel uncomfortable about this, please mention this to the organizers (or anyone with a camera).**
