在这个主题中,冯春培 和我们分享了阿里巴巴去Oracle,选择MySQL以及之后对于其他数据库产品的使用和尝试,这些亲历者的讲述对我们尤其具有参考价值。

【IT168资讯】由IT168(ITPUB、IXPUB、ChinaUnix)主办的2012中国数据库技术大会(DTCC)于(以下简称大 会)2012年4月13日~15日在北京召开。

在4月15 日上午召开的DBA管理行为专场6上来自支付宝数据平台负责人、阿里巴巴首席DBA冯春培就"数据之路:技术创新与业务实践"作了主题发言。

  在主题发言中,冯春培详细的给DBA介绍了阿里的数据库应用历程。之前在我们数据库大会现场来自淘宝的DBA丁原为我们介绍了淘宝放弃ORACLE,选用MYSQL的原因,详细见《弃Oracle选mysql 解读淘宝开源应用实践》,而冯春培则向DBA介绍了阿里选择MYSQL的细节历程。

解秘阿里放弃ORACLE选MYSQL精险历程

▲支付宝数据平台负责人、阿里巴巴首席DBA冯春培

冯春培指出:

淘宝最早用的MYSQL,后来向ORACLE迁移。由于PHP当时在数据库方面的问题,淘宝当时从MYSQL切入到了ORACLE。在这个过程中,由于架构是处于雏形阶段所以,技术能力以及架构能力都是偏弱的。

据冯春培介绍,互联网企业的DBA承受的压力非常大,早在在2004年时,数据库经常出问题的。后来, 随着业务的发超速发展, ORACLE的优化还是承载不了业务的发展,于是开始拆分,当时在淘宝和阿里巴巴有不同的思路,这个时候会有不同业务为主体的拆分。这些事情完成由于涉及到安全、交易、涉及到数据的稳定性问题, DB已经不能做了,这个时候就需要架构开始受到重视。

从2007年到 2009年的这个阶段,架构的作用非常大。这个阶段,阿里系涌现出一系列架构师

当这个事情做完之后怎么样考虑企业成本的问题?

这个大背景下2002年随着互联网社区飞速发展,ORACLE的发展处于黄金时段,DBA的成长也非常快。

阿里在2006年开始考虑ORACLE和企业之间的联系。当时我们了解到国内某银行使用服务商的全套产品(硬件+软件)以后,无法替换,因此我们在预测一旦由一家服务商绑定,我们的风险有多大,于是我们准备了向MYSQL的转移。但是准备时,我们团队主要是是ORACLE,而MYSQL谁去学呢?

  当然,从培养新人开始做起,在这条路上走得很扎实, 到了2008年底的时候,在整个集团要不要引入MYSQL?要不要有计划性的向MYSQL迁移?有许多的反对声音。第二、开发的人员也不一定认同,在ORALCE上很顺手,觉得用MYSQL阻力很高的。

  在阿里用MYSQL背后主要考虑的是成本

   我们往迁移MYSQL,我们预备花三年时候从一种数据库迁移到另外一种数据库。当时做这件事情的时候,阿里系和ORALCE签了一个 ULA,ORACLE的授权随便可能用。用三年的时间我们稳固的推进了MYSQL。冯春培指出,传统的关系型数据库在扩张方面没一家解决得好的。

  大数据对于DBA是一个机会

  冯春培指出,现在谈大数据时代,很多管理者或者业务负责人怎么认识到数据的重要性,还在一个转型的过度中。大数据未来对于DBA一个机会。我们必须理顺团队的发展,而选择在高速成长的企业是我们不二之选。
