I'm super excited to announce the first milestone release of Project Reactor! Project Reactor is a foundational framework for building asynchronous, FastData applications on the JVM. Some of the goodness in Reactor 1.0.0.M1 includes: reactive composition helpers Stream and Promise, a TcpServer and TcpClient, and Groovy and Spring support. Reactor is designed, from the ground up, to be a high-performance, high-scale platform for building the next generation of big data applications. It provides simple tools for chaining asynchronous tasks together and makes executing those tasks as easy as calling a single method.
