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 8 functional API, Completable Future, Stream and Duration.
Reactor offers 2 reactive composable API Flux [N] and Mono [0|1] extensively implementing Reactive Extensions.
Suited for Microservices Architecture, Reactor offers backpressure-ready network engines for HTTP (including Websockets), TCP and UDP. Reactive Encoding/Decoding is fully supported.
Reactor Processors, Operators and Timers can sustain high throughput rates on the order of 10's of millions of messages per second. Plus its low memory footprint should go under most of the radars. Reactor is part of an ongoing research effort to challenge further the possible flow optimizations.
As a Reactive Engine/SPI, both Reactor Core and IO modules expose reactive streams constructs for focused use cases, eventually combined with Spring, RxJava, Akka Streams, Ratpack... As a Reactive API, reactor framework modules will offer rich consumable features like composition and pub-sub eventing.
Scaling-Out to overcome latency and slow microservices is an important tool. Cloud Native apps will have a better chance at effective scale-out with asychronous architectures. To assist such design, Reactor offers non-blocking and backpressure-ready embeddable solutions including local and remote Unicast/Multicast messaging or TCP/HTTP/UDP client & servers.
