Where did MongoDB come from, anyway? What are its design goals and best use cases? How does it work internally? And why isn’t it more like Dynamo? While most talks about MongoDB describe how to use the system, this talk will focus on MongoDB’s design philosophy and how it contrasts with the design of other prominent database systems. Particular attention will be paid to MongoDB’s approach to durability and scaling, but there will also be time to highlight key internals like BSON and secondary indexes. After all that, a good chunk of time will be devoted to Q & A. Developers interested in database theory and curious about design principles should attend this talk. Bring your hard questions!
