title: How to scale socket.io without redis
body: <p>I'm currently searching for an alternative to scale my express app with socket.io. The problem is that I don't want to use redis as socket.io store. Are there any other possibilities to cluster socket.io except with <a href="https://github.com/fent/clusterhub" rel="nofollow">Clusterhub</a>?</p>
  
  <p>EDIT: I tried to use <a href="https://github.com/hdachev/fakeredis" rel="nofollow">fakeredis</a> as replacement for redis, but it seems like it doesn't work with socket.io. From <a href="https://github.com/evantahler/actionhero" rel="nofollow">ActionHero.js</a> I know that faye-websocket works with fakeredis.</p>
