Thanks rcruz. Redis has a few advantages over other NoSQL databases<p>1. Redis is a Disk-backed in-memory database so its blazing fast.
2. Redis also has an easy pub/sub built in so you can easily use it communicate between servers in your nodejs cluser.
3. Kue is an amazing open source priority queue which uses it as a backend by default.<p>For small datasets that don't require you to query within your json, its an amazing database.
