Node.js clustering with socket.io and mysql sessionstore

I'm trying to cluster a node app that runs with mysql, mysql session store and massive usage of socket.io. I was looking for a way to adapt the socket.io session storage in mysql but i only found some redis adapter (following this guidelines : https://github.com/elad/node-cluster-socket.io)

Is there a way to implement node clustering with socket.io and mysql without installing redis ?
