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.
MySQL Community Source
MySQL source for each release of TokuDB can be downloaded under the GPLv2 license from the links below. Each source tar file includes all Tokutek patches for the MySQL binary released with the corresponding version of TokuDB.
