Atmoshpere & Asynchronous Servlet

Last week, I was at Devoxx and I attended to a speech of JF Arcan, the head architect of the Atmoshpere framework [1]. While the new coming Servlet 3.0 Async provides

  • Method to suspend a response, HttpServletRequest.startAsync()
  • Method to resume a response: AsyncContext.complete()

Atmosphere offers:

  • Annotation to suspend: @Suspend
  • Annotation or resume: @Resume
  • Annotation to broadcast (or push) events to the set of suspended responses: @Broadcast
  • Annotation to filter and serialize broadcasted events using BroadcasterFilter

In [2], JF Arcand demonstrates how Atmosphere can be used to suspend a request but also broadcasting a message to all suspended threads. Atmoshpere defines the notion of broadcastable and topics.
