This document discusses the need for a new data management paradigm called M3 to address issues with scaling user data. It proposes a "DataOS" platform based on M3 principles that would provide a performant, scalable, and low-cost way to manage shared data and analytics across applications in a cloud environment. The DataOS adopts the M3 approach of decoupling data from applications, making all data universally addressable, and separating real-time and batch processing for better performance and scalability.
