Reactor - a foundation for asynchronous applications on the JVM

Reactor was recently made public after a two-year incubation, evolving slowly alongside frameworks like Storm, Akka, Play, GPars or Vert.x. Integrated with Grails starting with version 2.3, Reactor takes the best ideas from several asynchronous toolsets and synthesizes them into a coherent framework that supports a variety of runtime topologies and makes it easy for developers to efficiently leverage their cloud or traditional hardware assets. Reactor is equally at home inside or outside a Spring ApplicationContext and also provides first-class Groovy support in the form of DSLs and language extensions. Special attention has been given to make Reactor easy enough to use to create single-file node.js-like applications, while maintaining a solid asynchronous toolset that works with Big and Fast Data tools like Gemfire, Spring Integration, and Spring Batch. This talk will give Reactor a proper introduction and show sample code that demonstrates the event-driven and composition-based nature of Reactor applications.

Session Detail

Grails and the Realtime Web

Grails 2.3 is coming with new asynchronous and eventing features, driven by the same usability that shapes the Grails success amid developers. That means the framework now supports the modern definition of "realtime".

In fact, Platform-core plugin currently helps developers at writing Event-Driven Architectures and pushes the boundaries to the Browser with its Events-Push extension. Scalability might also be an outcome of such architecture, since multiple Grails applications can now easily work together. Eventually, with events propagated across server(s) and browsers, a new set of patterns emerges and HTML5 web applications have rarely been so pleasant to write.

We'll see in this session how we address few spotted today's and tomorrow's concerns: Scrolling large data sets without blocking, streaming to the browser, scale Grails in the cloud...
