Last wednesday, I gave a presentation on NoSQL databases at the East Bay Java User Group (@oakjug), which meets monthly in downtown Oakland, CA. The talk gives an overview of NoSQL and compares and contrasts Redis, Cassandra and MongoDB using a use case from my book POJOs in Action. There was a pretty good turnout but the meeting was still small enough to be extremely interactive. There were lots of great questions and I got some good ideas on how to improve the next version of the talk.
Here are the slides:
