Drizzle 7.0, Future of Virtualizing
This document discusses the history and features of Drizzle, an open source relational database management system (RDBMS). Drizzle was created in response to Oracle's acquisition of Sun Microsystems and MySQL. It uses a microkernel design and pluggable interfaces to provide features like asynchronous replication, table functions for metadata access, and integrated hot backups without locking for high availability. The document promotes Drizzle's scalability and lack of "gotchas" compared to other database solutions.
