title: End to end example of CQRS implementation on top of AppEngine
body: <p>All of the infrastructure components required to implement a <a href="http://cqrsinfo.com/" rel="nofollow">CQRS</a> based application seem to be out of the box within AppEngine. </p>
  
  <p>Unfortunately, I can't find anything related to this subject.</p>
  
  <p>Few possible reasons</p>
  
  <ul>
  <li>It's a well kept secret beyond "Architecture Astronauts"</li>
  <li>It's a worthless overkill architecture because AppEngine scales out "by design"</li>
  <li>It's not mainstream yet</li>
  </ul>
  
  <p>However, even if no complete code is available, provided anyone has hints, bits of targeted code, pros/cons regarding CQRS on top of AppEngine, I'd be greatly honored to benefit from your knowledge.   </p>
  
  <p>Thanks in advance.  </p>
  
  <p><em>Note 1: At least, a similar project exists in the .Net ecosystem (Lokad-CQRS which targets Windows Azure)<br>
  Note 2: Even if I'm rather python inclined, answers related to Java experience are welcome</em></p>
