近日,全球最大的自由、免费、内容开放的网络百科全书Wikipedia正式从MySQL迁移到MariaDB数据库。

在做正式迁移前Wikipedia做了大量的准备工作,包括兼容性测试和性能测试,详情请看官方说明。此前,2012年CSDN研发频道曾报道过Wikipedia开发者Asher Feldman宣称将英文维基的一个(slave)数据库从MySQL5.1 + Facebook补丁集迁移到了MariaDB 5.5.28。

如今,时隔将近半年,Wikipedia正式完成迁移。

维基百科正式从MySQL迁移到MariaDB数据库

MariaDB是一个社区驱动的、采用XtraDb存储引擎的MySQL分支版本,由MySQL创始人Michael Widenius带领开发,遵循GPL v2.0协议开源。          

与MySQL相比较,MariaDB的优势在于:

  • 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

据Solidot 的报道获悉:MySQL是世界上最流行的开源关系数据,它的名字取自于创始人Michael "Monty" Widenius的长女“My”。2008年,Sun收购MySQL;2009年,甲骨文收购了Sun,MySQL落入了与开源社区关系紧张的甲骨文手中。Widenius与他的旧团队在2009初创建了MySQL的分支MariaDB,它的名字取自于Widenius的幼女“Maria”,他希望通过保留核心开发者和日益增长的社区帮助MariaDB挑战甲骨文的MySQL。

Wikipedia宣布从MySQL迁移到MariaDB,部分原因是甲骨文的MySQL有免费版和企业版,企业版的新功能没有公开源码,而MariaDB则没有这方面的问题。
