Hi Lahiru, I am afraid it's in an unusable state atm mainly due to my fault. I would also like to take this opportunity to discuss the continuity of the amqp transport.
The motivation behind creating an AMQP specific transport instead of using it via the JMS transport was due to the perceived flexibility & performance achieved via a transport that is close to the protocol. However as Qpid gained more experience and myself having the privilege of working with customers and end users realized that the JMS implementation is lacking this flexibility more due to design issues than any real issue with the API itself. Over the last year or so we made significant improvements to the JMS client. The new address format that will be used by all the Qpid clients including JMS will be rich enough to tune protocol specifics via the javax.jms.Destination abstraction while allowing applications to use pure JMS without having to resort to a vendor specific low level API. Going forward management aspects such as having to create queues/exchanges dynamically could be done by sending a map message than invoking a protocol command. Infact in AMQP 1.0 management/admin work such as declaring queues are not protocol specific commands any more. They are achieved via sending messages to a known admin/mgt service within a container. There was also quite a bit of performance work done in the JMS client to the extent the difference btw the JMS layer and lower layer is negligible for a real business application especially within the context of Synapse. In artificial benchmarks the diff is about 10k msg/sec. Therefore with the benefit of hindsight I feel that having an AMQP specific transport doesn't add anything significant over the well tested JMS transport that Synapse has. However before coming to a conclusion, it would be worthwhile to figure out all the use cases around AMQP with Synapse. Then we could document how they could be achieved via the JMS transport. If there are any use cases that cannot be reasonably met, then perhaps we could discuss about an AMQP specific transport.
