A full day with three (3) tracks on MongoDB.
Just some titles at random to awake your interest: Indexes, What Indexes?, Scaling MongoDB for Real-Time Analytics, Intelligent Stream Filtering Using MongoDB, GeoSpatial Indexing. That 4 out of 25.
My suggestion is that you visit and find presentations relevant to your topic map interests. Enjoy!
BTW, another 20 or so presentations on MongoDB from the MongoUK event in March, 2011.
