Percona Server for MySQL is a MySQL relational database management system build created by Percona, which was founded by Peter Zaitsev and Vadim Tkachenko in 2006. It contains several scalability, availability, security and backup features only available in the paid, premium version of the official MySQL release. It uses XtraDB, an enhanced version of the InnoDB Storage Engine, by default, and retains full compatibility with InnoDB. It provides ACID (atomicity, consistency, isolation, durability) and MVCC (multiversion concurrency control). Distributed under the GNU GPL.
