Percona has been adding more and more custom features to the Percona MySQL build, which significantly enhances the manageability and functionality of the MySQL server.  The patches include features such as fine-grained query logging and user, table, and index statistics, as well as many other additions.  Some of the functionality is based on well-known patches from others, such as Google; some is uniquely available from Percona.

Percona makes the modifications available in source code form and as packages for RHEL, CentOS, and others. The Percona development team is also continuing to build an experimental high-performance patchset based on groundbreaking work with the InnoDB storage engine, targeted at reducing internal contention and greatly increasing the engine's ability to take advantage of today's multi-core, large-memory commodity hardware.

"Our patches are designed in response to the needs of our customers' mission-critical systems, and solve real-world problems in some of today's largest and most demanding MySQL installations," says Vadim Tkachenko, Percona's CTO and head of development.  "Some patches are sponsored by customers, and some are pro bono."  Tkachenko adds that MySQL users who need customizations to the MySQL server often turn to Percona, which has a staff of several full-time developers who build MySQL server enhancements and custom features.
