Project Reactor - Create efficient Reactive systems

Reactor is a fourth-generation Reactive library for building non-blocking applications on the JVM based on the Reactive Streams Specification. Reactor is a fully non-blocking foundation with efficient demand management. It directly interacts with Java functional API, Completable Future, Stream and Duration. Reactor Operators and Schedulers can sustain high throughput rates on the order of 10's of millions of messages per second.
