title: Node.js cluster and socket.io with mongodb as store
body: <p>I've got a problem to set up clustered <strong>node.js / socket.io</strong> app, with socket.io store, based not on Redis but on MongoDB.
  I need to mention that my app uses Mongo to store data. So I don't want to setup another DB just to make soket.io works across multiple process.</p>
  
  <p>I found an option - <a href="https://npmjs.org/package/mong.socket.io" rel="nofollow">mong.socket.io</a>, but it looks like I can't make this work with node clusters.
  I'm using <strong>node: 0.10.10</strong>, with <strong>socket.io: 0.9</strong><br />
  I'm looking for any solution that will let me use MongoDB as a store for socket.io that runs on separate processes. </p>
