I guess that we more often think about our services in “happy path” term, but we underestimate not so happy paths. What if my API is trying to reach another API/system and it is failing constantly? Can I reach it less often in case of timeout? I thought about that in case of a Mule 4 application and I come up with Circuit Breaker pattern. In this article I will briefly introduce the pattern and show you how you use it in your Mule application.
Sometime it is needed to use custom JAVA code to processes current message. Developed custom code is known as Java Component. How mule knows which method should invoke and what parameters should be there passed? There are some rules that your class may full fill in order to work without any additional configuration. However when you have more sophisticated use case or class is fairly complex you would probably need Entry Point Resolver configured. I will explain on simple examples some of them. This is valid for Mule version 3.x. In next article I will describe in more detail new Java Module available in version 4.x.
