A few years ago, when NoSQL was trending, like every other team, our team was also enthusiastic about the new and exciting stuff; we were planning to change the database in one of the applications. But when we got into the finer details of the implementation, we remembered what a wise man once said, “the devil is in the details,” and eventually, we realized that NoSQL is not a silver bullet to fix all problems, and the answer to NoSQL VS RDMS was: “it depends.” Similarly, in the last year, concurrency libraries like RxJava and Spring Reactor were trending with enthusiastic statements, like the asynchronous, non-blocking approach is the way to go, etc. In order to not make the same mistake again, we tried to evaluate how concurrency frameworks like ExecutorService, RxJava, Disruptor, and Akka differ from one another and how to identify the right use case for respective frameworks.
