Up until this point, we have discussed Reactor as a standalone framework. We have also seen how we can build publishers and subscribe to them.

SpringMVC can also serve asynchronous non-blocking data using Servlet 3.1, but then it moves away from the concepts of request mappers and filters. This makes the framework quite difficult to work with. Furthermore, when building microservice architecture for high performance, the framework may not be the optimum choice. With such an architecture...
