title: Use-cases for reactive streams using java 9 Flows in Servlets?
body: <p>I'm looking for use-cases for using reactive streams within a servlet container (or just a HTTP server).</p>
  
  <p>The <a href="http://eclipse.org/jetty">Jetty project</a> has started being asked: "is Jetty reactive?" and we've noticed the <a href="http://cs.oswego.edu/pipermail/concurrency-interest/2015-January/013641.html">proposal</a> to add reactive streams to java 9.</p>
  
  <p>So we've started <a href="https://github.com/jetty-project/jetty-reactive">some experiments</a> with using the reactive streams API for async servlet IO, which are interesting enough..... but lack any focus because we lack real use-cases to focus which concerns are most important.</p>
  
  <p>So does anybody have any good use-cases that they could share/explain so that we can direct our jetty experiments to meet their needs.    The sort of thing I've imagined is having a RS based database publisher sending objects all the way out on a HTTP response or websocket connection using Flow.Processors for the conversions along the way.  </p>
