> Message Cut-Through/Streaming for efficient handling of large messages
> ----------------------------------------------------------------------
>
> Key: DISPATCH-767
> URL: https://issues.apache.org/jira/browse/DISPATCH-767
> Project: Qpid Dispatch
> Issue Type: Improvement
> Components: Router Node
> Reporter: Ted Ross
> Assignee: Ganesh Murthy
> Fix For: 1.0.0
>
>
> When large, multi-frame messages are sent through the router, there is no
> need to wait for the entire message to arrive before starting to send it
> onward.
> This feature causes the router to route the first frame and allow subsequent
> frames in a delivery to be streamed out in pipeline fashion. Ideally, the
> memory usage in the router should only involve pending frames. This would
> allow the router to handle arbitrary numbers of concurrent arbitrarily large
> messages.
