Reactive Programming is interesting (again) and there is a lot of noise about it at the moment, not all of which is very easy to understand for an outsider and simple enterprise Java developer, such as the author. With its latest releases (starting with Java 8), Java itself has made some attempts to introduce built-in reactivity, yet these attempts are not very popular with developers to date. Reactive Programming Questions: Explain the actor model. Unfortunately, as it often happens, the new concept quickly fueled a set of misinterpretations around itself, and still continues doing so today. Whether you want to leverage non-blocking APIs, manage the latency introduced by the explosion … Reactive programming (RP) is not something new and cutting-edge when it comes to application development. ... Summary. Reactive, what an overloaded word.Many things turn out to become magically Reactive these days. Reactive programming has several obvious advantages, such as: If your project requires upgrades in such spheres as data dependencies, the safety of the tread, the connection between components, or managing async tasks, you should think about reactive programming. Everything that happens or changes in an application (calls, notifications, users’ actions, system errors, etc.) It will be the right solution in case of high-load and multi-user applications, for example, social networks, games, audio, or video applications.
