Pivotal's Reactor project

The Pivotal team has developed a new module to support RP features, which is known as Reactor. They have released it as part of Spring Framework 5.x.

The Spring Framework is a Java framework to develop web applications, microserivces, and more. Its 5.x version is built on the Reactor module and also supports the API to develop Reactive applications. This module builds directly on the Reactive Streams Specification, so we don't need to use any bridge or adapters. Spring Framework has another module known as Reactor IO, which provides wrappers around low-level network runtimes, such as Netty and Aeron.
