Percona Server是MySQL的改进版本，使用 XtraDB 存储引擎，在功能和性能上较 MySQL 有着很显著的提升，如提升了在高负载情况下的 InnoDB 的性能，为 DBA 提供了一些非常有用的性能诊断工具，另外有更多的参数和命令来控制服务器行为。

Percona Server 5.6.21-70.1 发布，该版本主要是 bug 修复，包括：

A slave replicating in RBR mode would crash, if a table definition between master and slave differs with an allowed conversion, and the binary log contains a table map event followed by two row log events. This bug is an upstream regression introduced by a fix for bug #72610. Bug fixed #1380010.
An incorrect source code function attribute would cause MySQL to crash on an InnoDB row write, if compiled with a recent GCC with certain compilation options. Bug fixed #1390695 (upstream #74842).
MTR tests for Response Time Distribution were not packaged in binary packages. Bug fixed #1387170.
The RPM packages provided for CentOS 5 were built using a debugging information format which is not supported in the gdb version included with CentOS 5.10. Bug fixed #1388972.
A session on a server in mixed mode binlogging would switch to row-based binlogging whenever a temporary table was created and then queried. This switch would last until the session end or until all temporary tables in the session were dropped. This was unnecessarily restrictive and has been fixed so that only the statements involving temporary tables were logged in the row-based format whereas the rest of the statements would continue to use the statement-based logging. Bug fixed #1313901 (upstream #72475).

其他 bug 还包括: #1387227, and #1388001.
