You're only limited by the size of your pipe. If you're familiar with MongoDB then you'll feel write at home with Mango. We'll instantly map all of your existing data without ANY EFFORT with a new and improved AUTO SHARTING ALGORITHM. +Background and motivation +------------------------- + +The main problem with traditional database engines is that they are not web scale. +MongoDB provides an elegant solution to web scaling but does not go all the way, suffering from the scalability-limiting +constraint known as "possible durability". + +The "possible durability" problem is introduced in the CAPD conjecture, +based on the http://en.wikipedia.org/wiki/CAP_theorem and taking into account durability. + +MangoDB goes further: by implementing a new approach that removes MongoDB's "possible durability" constraints, +MangoDB can reach new levels of web scalability. + +Watch this video for a discussion on the "possible durability" problem: +http://www.youtube.com/watch?v=b2F-DItXtZs + + Getting Started ---------------
