Mariadb

简介

MariaDB is a community developed branch of MySQL. It's a branch of MySQL (ie, we are keeping our code in sync with MySQL) and contains in addition the Maria storage engine, updated version of other storage engines and extensions.

版本策略:目前所有MariaDB发行版都基于 MySQL 5.1. 当 MySQL 5.5 或 MySQL 5.6 变成 RC , 将切换到 MariaDB beta 版并基于RC版本上.
