Chapter 2. Enhancements

ENTMQIC-1905 - Support for large messages - Message Streaming

AMQ Interconnect has been enhanced to better support large messages. Previously, when receiving a message, the router waited to receive the entire message before sending it to its receivers. This led to slow throughput for large messages.

Starting in AMQ Interconnect 1.1, the router sends frames to the receivers when they arrive at the router, and releases the memory immediately after sending the buffer to all receivers. This keeps the memory stable on the router even if there are a large number of senders sending large messages. In addition, messages are delivered more quickly to the receivers, thus increasing throughput because frames are sent when they are received and not held until the entire message arrives at the router.

In addition, multicast streaming is now supported as part of this enhancement.
