title: Apache Camel/ActiveMQ priority route
body: <p>I have two AMQ queues that have the same consumers.
  The first queue (Q1) handles 97% of the messages and the other (Q2) only 3%.
  Problem is that messages in Q2 need to process messages as soon as they are queued.
  So my problem is that when a message is available in Q2 I need somehow to suspend the first route to take it's consumers.
  The apache camel routing looks like this:</p>
  
  <pre><code>&lt;route id="q1"&gt;
      &lt;from uri="jms:recordAnalysisRequests" /&gt;
      &lt;to uri="bean:analysisService" /&gt;
  &lt;/route&gt;
  &lt;route id="q2"&gt;
      &lt;from uri="jms:recordAnalysisRequestsFastTrack" /&gt;
      &lt;to uri="bean:analysisService" /&gt;
  &lt;/route&gt;
  </code></pre>
  
  <p>What strategy should use?
  I don't think I can use resequencer because Q1 could have thousands of messages queued up and I cannot fit all in a resequencer batch.
  I was looking at the route throttling but I cannot figure out how to do it.
  Also I was wondering if I can synchronize through a zookeeper node. Again I will need some guidance here if this solution is viable.</p>
