Tokutek is proud to be an on-going contributor to open source MySQL. We believe that we and the MySQL community at large all benefit from the additional features, bug fixes, and performance improvements we contribute. And of course, we also contribute patches that help MySQL’s BerkeleyDB API to provide optimal performance and support for our TokuDB storage engine.
We have contributed our patches to both MySQL and MariaDB, and they are available as OpenSource under the GPLv2 license.
