Meaning, Vert. How does this impact you and your application? Wanna use another Vert. Starting the application is a simple class with the public static void main String args entry point. No specific IDE or plugin to install to start using Vert.
About Vert. Reactive programming is a programming paradigm, associated with asynchronous streams, which respond to any changes or events. Similarly, Vert. Setup To use Vert. Verticles Verticles are pieces of code that Vert.
The toolkit provides us many abstract verticle class, which can be extended, and implemented as we want to.
Being polyglot, verticles can be written in any of the supported languages. An application would typically be composed of multiple verticles running in the same Vert. To create a verticle in JAVA, the class must implement io. Verticle interface, or any one of its subclasses.
Event Bus It is the nerve system of any Vert. We then extract the body of the message 5 and subscribe to the Rx chain: if we receive the message, we print it 6. Would you like to do some more complex stuff? Have a look at the repeatWhen.
Is that all? Well, no. Guess what?
There is a third way to do it! Retry with the circuit-breaker The circuit-breaker is a very popular pattern in the micro-services world: it enables to handle reliability and failure. Whenever a failure occurs, the circuit-breaker increases its counter of failure.
The original operation is not called anymore but you can supply a fallback instead. And guess what? There are lots of options to configure your circuit-breaker. We will focus only on the retry feature. Then, we wrap our call with the circuit-breaker 2. The execute. The wrapped operation will then complete 4 or fail 5 the given future.
A handler will deal with the result of the execution of the circuit-breaker 6. The circuit-breaker offers nice options: fallback, timeout, etc. Depending on your business logic, it may be worthwhile having a look at it. Conclusion With the Vert. Depending on your business logic, you can opt for a simple retry with a Handler or with a Rx-ified version and the retry. RxJava offers nice operators that can give you powerful options to implement more complex retry logics.
