In the past few years, reactive programming has developed increasingly as an alternative to classic programming models. Especially in the area of highly scalable applications, reactive programming offers advantages in terms of performance and reliability.
Reactive programming is able to recognize the load of an application during operation and to adapt the operation depending on the load. Especially in scenarios with high concurrency, the reactive programming model also prevents most classic errors caused by multi-threading.
Reactive programming is defined as message-based in the Reactive manifest. This encapsulation facilitates a clearly defined public interface, which hides the internal workings of larger modules and allows applications to be efficiently split into Microservices.
