Inventor's Paradox

Background In this post I would tell a story about installing MariaDB in Ubuntu Trusty, and the process that I went through to enable TokuDB engine. I need to experiment using the engine as an alternative to the Archive engine, to store compressed table rows. It have better performance than InnoDB tables (row_format=compressed), and it was recommended in some blog posts (this post  and this )  Packages for Ubuntu Trusty In order to be able to use TokuDB, I seek the documentation and find out that Ubuntu version 12.10 and newer for 64-bit platform requires  mariadb-tokudb-engine-5.5  package.  Despite the existence of mariadb-5.5 packages, I found no package containing tokudb keyword in the official Ubuntu Trusty repositories.

From governance point of view, linux software should be installed in native packagers such as using dpkg or rpm, so this is one minus point that the oracle's java license prevented the crea...
