RxJava: Reactive Extensions for the JVM

RxJava is a Java VM implementation of Reactive Extensions: a library for composing asynchronous and event-based programs by using observable sequences.

It extends the observer pattern to support sequences of data/events and adds operators that allow you to compose sequences together declaratively while abstracting away concerns about things like low-level threading, synchronization, thread-safety and concurrent data structures.

Zero Dependencies
< 700KB Jar
Java 6+ & Android 2.3+
Java 8 lambda support
Polyglot (Scala, Groovy, Clojure and Kotlin)
Non-opinionated about source of concurrency (threads, pools, event loops, fibers, actors, etc)
Async or synchronous execution
Virtual time and schedulers for parameterized concurrency

Versioning

As of 1.0.0 RxJava is following semantic versioning. During the 0.x.y releases, the minor (.x) releases were breaking changes.

The 0.x releases were published under the com.netflix.rxjava GroupId. The 1.x releases are published under io.reactivex. All usage of 0.x and com.netflix.rxjava should eventually be migrated to 1.x and io.reactivex. This was done as part of the migration of the project from Netflix/RxJava to ReactiveX/RxJava.

During the transition it will be possible for an application to resolve both the com.netflix.rxjava and io.reactivex artifacts. This is unfortunate but was accepted as a reasonable cost for adopting the new name as we hit version 1.0.

The 0.20.x branch is being maintained with bug fixes on the com.netflix.rxjava GroupId until version 1.0 Final is released to allow time to migrate between the artifacts.
