Rafael,
Thanks for responding. The only reason why I said it wouldn't be portable is because when I saw the CMake files I thought I'd have to build it to bind C functions from the engine to Python. However, if I can perform the p2p messaging just using the proton.py then that would work. My scenario is the following: I have three Python modules running. One is a web service that takes incoming requests and places the request data as a message on an incoming queue, then another Python service listens on the incoming queue and processes the data in the messages. After it finishes processing the data it passes the results as another message onto an outgoing queue which is then grabbed by the last Python service and sent back. Previously I was using the Java Qpid broker because I need persistence enabled so that if the Qpid broker or one of these Python services were to fail during a queue transaction, the services, when restarted, would be able to pickup the durable message and continue the data flow. While it works great with the Qpid broker, the main issue is that the Qpid broker is just too heavy. I need a fast lightweight version that still offers the basic persistence (I was using Derby store) and ideally written in Python since all of my code is in Python. I don't have any specific performance requirements other than saying the faster the better. Right now all of the queueing is done locally between these services, but I would like to have the ability to extend it easily to work over networked machines which I know Proton can do. Do you think it's overkill to use something like Qpid or Proton in my scenario?

The latest release of the cpp broker uses proton to provide AMQP 1.0 support, and we plan to use it in future releases of the Java broker also. That said, Proton is definitely intended to be used independently of either the cpp or Java broker, and can be used without either (i.e. peer to peer), so in that sense the answer to your question is yes. There is definitely interest in building a lightweight queuing component that works well with Proton and can be flexibly deployed in a variety of topologies, and even dynamically/transparently redeployed at runtime. A python prototype has been discussed as a starting point for some of this work, and there has been other work ongoing both in terms of re-factoring the cpp broker and in terms of prototyping new servers that may ultimately contribute. Why do you think your own queuing server built in python wouldn't be portable? Can you describe a little bit more about your scenario, e.g. do you need persistence, transactions, etc ...? Do you have any particular performance requirements? Can you describe your messaging topology at all? --Rafael
