We recently gave this talk at the local Boston MongoDB Meetup group. It’s a walkthrough of Traackr’s experience in choosing a NoSQL solution and how we ended up up switching from HBase to MongoDB. This deck goes through some in depth technical aspects, like schema design and our use of secondary indexes. BTW, the attendance at the meetup was great. We love the Mongo community in general and are looking forward to continuing to work with them and 10gen.
