Percona Server Mysql分支数据库
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 5.5.53-38.4 发布了。该版本基于MySQL 5.5.53。
更新内容：
新特性：
Metrics for scalability measurement feature has been removed. WARNING: if you have scalability_metrics_control variable in your my.cnf configuration file you’ll need to remove it, otherwise server won’t be able to start.
Bug 修复：
When a stored routine would call an “administrative” command such as OPTIMIZE TABLE, ANALYZE TABLE, ALTER TABLE, CREATE/DROP INDEX, etc. the effective value of log_slow_sp_statements was overwritten by the value of log_slow_admin_statements. Bug fixed #719368.
Thread Pool thread limit reached and failed to create thread messages are now printed on the first occurrence as well. Bug fixed #1636500.
