2月24日消息,据外电报道,Twitter公司一位名叫Ryan King的工程师日前向博客MyNoSQL透露,公司计划从MySQL迁移到Cassandra数据库,因为后者具有更大的弹性、可扩展性和大量的社区网络开源开发人员。
我们有大量的数据,在数据巨大,增长率正在加速的情况下,我们需要一个系统,它可以更为自动化,并高度可靠、可用。Ryan King表示。
相关数据显示,在2009年里,Twitter用户数从1月份的每天约 200万人,激增至12月份的每天近5000万人。每天登陆Twitter的用户数量增长已经超过了20倍。
事实上,对于熟练的程序员来说,所谓的NoSQL数据库可以提高性能和可扩展性,这使得它们吸引消费者的网络世界。
像Facebook和Twitter,以及最初的Web 2.0的宠儿Digg,也正从MySQL数据库迁移到Cassandra数据库。
Ryan King表示,试验发现,Cassandra数据库比MySQL更具有可扩展性、可靠和更易于管理。
把装有所有tweets和 retweets信息的平台迁移到Cassandra上去,这是Twitter的当前要务。Ryan King说。在这之后,我们将开始把一些新的项目迁移到Cassandra或者其他的平台。
