Slides: http://www.slideshare.net/christkv/lessons-from-4-years-of-driver-develoment Its been 4 years since I started on the MongoDB driver and I'll share my trip through frustration and excitement pointing out all the things I did wrong and some of the things I'm kind of certain that I got right (more or less). History of the driver, challenges, gotchas, performance. License: For reuse of this video under a more permissive license please get in touch with us.
