MariaDB 是一个采用 Aria 存储引擎的 MySQL 分支版本，是由原来 MySQL 的作者 Michael Widenius 创办的公司所开发的免费开源的数据库服务器。

与 MySQL 相比较，MariaDB 更强的地方在于：

• Maria 存储引擎

• PBXT 存储引擎

• XtraDB 存储引擎

• FederatedX 存储引擎

• 更快的复制查询处理

• 线程池

• 更少的警告和bug

• 运行速度更快

• 更多的 Extensions (More index parts, new startup options etc)

• 更好的功能测试

• 数据表消除

• 慢查询日志的扩展统计

• 支持对 Unicode 的排序
