This document provides an overview of the design philosophy and goals for the Drizzle database system. Key points include removing old locks and focusing on today, leveraging multi-core CPUs by using copy-on-write and message passing for scaling, moving code to the edge and removing unnecessary features from the core, using pluggable authentication and dumping access control lists, adopting UTF-8 and weakly typed fields, and maintaining an open source development model through Launchpad.
