完全改进:5.6.17

Percona Server 5.6.17-65.0

Percona is glad to announce the release of Percona Server 5.6.17-65.0 on May 6th, 2014 (Downloads are available here and from the Percona Software Repositories).

Based on MySQL 5.6.17, including all the bug fixes in it, Percona Server 5.6.17-65.0 is the current GA release in the Percona Server 5.6 series. All of Percona‘s software is open-source and free, all the details of the release can be found in the 5.6.17-65.0 milestone at Launchpad.

New Features

Percona Server now supports Metrics for scalability measurement.

Percona Server now supports Audit Log Plugin.

Percona Server parser and query optimizer now support Multiple Clustering Keys when TokuDB engine is used.

Storage engine handler interface has been extended with new calls to notify the storage engine of imminent table or index scan. The calls are used by TokuDB to improve performance of these operations.

Percona Server packages are now available for Ubuntu 14.04.

Bugs Fixed

Percona Server couldn’t be built with Bison 3.0. Bug fixed #1262439,upstream #71250.

Fixed the inadequate background LRU flushing for write workloads with InnoDB compression that could lead to lower performance. Bug fixed #1295268.

Percona Server debug packages were not built for the previous releases. Bug fixed #1298352.

Queries that no longer exceedlong_query_timewere written to the slow query log if they matched the previouslong_query_timevalue when slow_query_log_use_global_control variable was set toall. Bug fixed #1016991.

When writing audit plugins it was not possible to get notifications for general-log events without enabling the general-log. Bug fixed #1182535 (upstream #60782).

mysqld_safedid not correctly parse flush_caches and numa_interleave options. Bug fixed #1231110.

Thread Pool would handle a new client connection without notifying Audit Plugin. Bug fixed #1282008.

Fixed a performance issue in extending tablespaces if running underfusionIOwith atomic writes enabled. Bug fixed #1286114 (Jan Lindström).

Previous implementation of the log_slow_rate_type set toquerywith log_slow_rate_limit feature would log every nth query deterministically instead of each query having a 1/n probability to get logged. Fixed by randomly selecting the queries to be logged instead of logging every nth query. Bug fixed #1287650.

Percona Server source files were referencing Maatkit instead of Percona Toolkit. Bug fixed #1174779.

Maximum allowed value for log_slow_rate_limit wasULONG_MAX(ie. either4294967295or18446744073709551615, depending on the platform). As it was unreasonable to configure the slow log for every four billionth session/query, new maximum allowed value is set to1000. Bug fixed #1290714.

Other bugs fixed #1295523, #1299688 (upstream #72163) and #1272732.

Percona一个专注于Linux的MySQL衍生版,提供一系列运维管理工具percona-toolkit、XtraBackup、Playback、tcprstat和Nagios、Cacti、Zabbix监控插件,支持MySQL社区办所没有的线程池,采用InnoDB改进版引擎XtraDB,著名的博客mysqlperformanceblog.com和书籍《High Performance MySQL》都出自Percona技术团队。

Percona官方提供有Ubuntu/Debian/Redhat/CentOS软件源,可以直接使用apt-get和yum安装,非常方便:
http://www.percona.com/doc/percona-server/5.6/installation.html

编译起来也很方便:
cmake . \
-DCMAKE_BUILD_TYPE=Release \
-DBUILD_CONFIG=mysql_release \
-DFEATURE_SET=community \
-DWITH_EMBEDDED_SERVER=OFF \
-DWITH_INNODB_MEMCACHED=ON \
-DCMAKE_INSTALL_PREFIX=/png/percona/5.6.16

make && make install

如果不指定-DCMAKE_INSTALL_PREFIX则默认安装到/usr/local/mysql。
如果你既要进行优化也要保留调试信息,-DCMAKE_BUILD_TYPE内容改为RelWithDebInfo,不保留调试信息则二进制文件更小。
-DBUILD_CONFIG=mysql_release 表示使用与Oracle官方相同的参数进行编译。
官方编译参数并不启用InnoDB Memcached插件功能,需要使用的话则需要-DWITH_INNODB_MEMCACHED=ON显式指定。

更多编译参数和配置请参看:
