Drizzle: A High-Performance Microkernel DBMS for Scale-Out Applications AbstractDrizzle is a community-driven project based on the popular MySQL DBMS that is focused on MySQL's original goals of ease-of-use, reliability and performance. The Drizzle team is removing non-essential code, refactoring the remaining code, switching to a microkernel architecture (with well-defined APIs) and generally making Drizzle into a lean, mean query-running machine. Participation is easy and fun.
