MongoSV was a four-track, one-day conference on December 3, 2010 at Microsoft Research Silicon Valley in Mountain View, CA. The main conference track featured 10gen founders Dwight Merriman and Eliot Horowitz, as well as Roger Bodamer, the head of 10gen’s west coast operations, and several of the key engineers developing the MongoDB project. These sessions were geared towards developers and administrators interested in learning how to use the database, with sessions on schema design, indexing, administration, deployment strategies, scaling, and other features. A second track showcased several high-profile deployments of the database at Shutterfly, Craigslist, IGN, Intuit, Wordnik, and more. For more experienced users of the database, there were several advanced sessions, covering the storage engine, replication, sharding, and consistency models.
Excellent collection of videos and slides on MongoDB and various aspects of its use.
