Re: [Openstack] ZeroMQ RPC Driver - FF-Exception request

2012-02-21 Thread Eric Windisch
It has been a pretty long month. I absorbed the community's comments, made improvements where they've been raised, and have also refactored to use fully asynchronous messaging. I won't say the driver isn't without bugs, but it is again fully-functional and feature complete. I've been working

Alexis, It is also obvious that the link I provided is a particularly biased source, so it should be taken with a grain of salt. I only mentioned Qpid because Nova just received a driver for it, I didn't know the differences in such detail. One of the problems Nova has is that it registers N

Under specific architectures, 0MQ can process millions of messages per second vs. RabbitMQ's many thousands. RabbitMQ is a messaging system; 0MQ is a messaging framework. There's a pretty good write-up on some of the basic differences here: http://www.zeromq.org/docs:welcome-from-amqp Note
