Kevin Calcagno, Lulu
Lulu is the leading self-publishing site on the web, with over 1.2 million books, eBooks, and calendars, each with its own user-generated metadata. This data is Lulu's entire business, and we learned a number of lessons migrating this mission critical data from PostgreSQL to MongoDB. This talk builds upon a September 2011 talk at Mongo Raleigh where we discussed why we chose a non-relational database. We'll also cover what we learned from backing MongoDB with NFS and from using Spring Data to integrate MongoDB into our code.
