Asynchronous Routing Engine
Available as of Camel 2.4
As of Camel 2.4 the asynchronous routing engine is back and kicking.
All the Enterprise Integration Patterns is supported as well a selected number of Components:
When we say a component is supported, that means, the component is leveraging the asynchronous model. For example Jetty uses continuations and the async http client to be fully asynchronous and non blocked. That means no threads will ever be blocked while waiting for a reply.
In the future additional Components will be supported as well where it's applicable.
Background information
