Asynchronous Java Applications on the JVM with Reactor

Reactor is a foundation for asynchronous applications on the JVM. It provides abstractions for Java, Groovy and other JVM languages to make building event and data-driven applications easier. It’s also really fast.

Reactor, as the name suggests, is heavily influenced by the well-known Reactor design pattern. But it is also influenced by other event-driven design practices, as well as several awesome JVM-based solutions that have been developed over the years. Reactor’s goal is to condense these ideas and patterns into a simple and reusable foundation for making event-driven programming much easier.

On modest hardware, it’s possible to process around 15,000,000 events per second with the fastest non-blocking Dispatcher. Other dispatchers are available to provide the developer with a range of choices from thread-pool style, long-running task execution to non-blocking, high-volume task dispatching. This video discusses the motivations behind the project, the design patterns and existing technology that inspired the project, and how it fits in the asynchronous ecosystem today.
