Percona XtraDB is an enhanced version of the InnoDB storage engine, designed to better scale on modern hardware, and including a variety of other features useful in high performance environments. It is fully backwards 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, to use memory more efficiently, and to be more convenient and useful. The new features are especially 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.
We are open for features requests for new engine and ready to accept community patches. You can monitor Percona’s current tasks and further plans on the Percona XtraDB Launchpad project. You can also request features and report bugs there. Also we have setup two maillists for General discussions and for Development related questions.
Percona XtraDB engine will not have further binary releases. XtraDB engine is distributed as part of Percona Server and MariaDB
Current stable release is Percona-Server-5.1.45-10:
