The Percona XtraDB storage engine

Percona XtraDB is an enhanced version of the InnoDB storage engine, designed to better scale on modern hardware. It also includes a variety of other features useful in high-performance environments. It is fully backward compatible, and so can be used as a drop-in replacement for standard InnoDB.

Percona XtraDB includes all of InnoDB ‘s robust, reliable ACID-compliant design and advanced MVCC architecture, and builds on that solid foundation with more features, more tunability, more metrics, and more scalability. In particular, it is designed to scale better on many cores, use memory more efficiently, and be more convenient and useful. The new features are specially designed to alleviate some of InnoDB’s limitations. We choose features and fixes based on customer requests and on our best judgment of real-world needs as a high-performance consulting company.

Percona XtraDB engine will not have further binary releases, it is distributed as part of the Percona Server for MySQL.
