It also allows you to do local decisions, without the actual need for a cloud upload. But as you know from sitting at your favorite restaurant, staring at the menu, making decisions can be quite hard ;-) Complex event process and machine learning models can help you with IoT use cases though.

AsyncAPI Java Tools 0.0.4 released
