Summary
In this chapter, we have learned the differences between imperative and reactive applications. We discussed briefly how to use MicroProfile Context Propagation to propagate contexts for asynchronous programming and then covered MicroProfile Reactive Messaging concepts to discuss how to use Reactive Messaging to create a reactive cloud-native application. Through this chapter, you will now be able to connect the built application with your chosen messaging technologies such as Apache Kafka. You also now understand that whenever you need to create a message-driven application, you should consider using MicroProfile Reactive Messaging.
In the next chapter, we will cover MicroProfile GraphQL to learn how to use GraphQL in your cloud-native applications to improve performance if you need to frequently execute queries.
