<p>For the first item in our deployed system we used the xmessagettl option when the queue is created. Messages expire after a certain amount of time. <a href="http://www.rabbitmq.com/extensions.html">http://www.rabbitmq.com/extensions.html</a></p>
<p>For the second one I would do it in the client and I don't know if rabbit supports it. Example in our system there are 10 consumer machines reading from the same queue, it goes quick when every node can filter out messages, if you have to parse through the contents of the message.</p>
