I had the pleasure of speaking at Mongo Seattle a few weeks back on how I use MongoDB for real-time data collection and analytics. The presentation ended up being a comparison of how I previously built TweetStats on top of MySQL and the terrible SQL queries that still power it to this day to how I would build it if I were using MongoDB. I also gave a couple use cases of how I’ve used MongoDB to power a game-based link shortener as well as my current primary focus, RowFeeder. I’ve you’d like a walk-through of MongoDB’s atomic incrementors and some map-reduce goodness, check out the slides below.
