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 backwards compatible, and so can be used as a drop-in replacement for standard InnoDB.
Percona XtraDB includes all of InnoDB ‘s robust, reliable
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.
Percona XtraDB engine will not have further binary releases, it is distributed as part of Percona Server for MySQL.
