Greenplum 精粹文集。 话说当年 Greenplum(当时还是一个 Startup 公司,创始人家门口有 一棵青梅 ——greenplum,因此而得名)召集了十几位业界大咖(据 说来自 google、yahoo、ibm 和 TD),说干就干,花了一年多的时间 完成最初的版本设计和开发,用软件实现了在开放 X86 平台上的分布 式并行计算,不依赖于任何专有硬件,达到的性能却远远超过传统高 昂的专有系统。 Big Date2 (分享一下开源的直接好处,最近我们某用户的一个特殊需求,加载 数据中有回车等特殊字符,我们下载了 GP 外部表 gpfdist 源代码,不 到一天就轻松搞定问题) Greenplum 也正在积极的拥抱云计算,Cloud Foundry 的 PaaS 云平 台正在技术考虑把 Greenplum MPP 做为 DaaS 服务来提供,对于 Mesos 或其它云计算技术的爱好者,也可以考虑采用容器镜像技术 + 集群资源框架管理技术来部署 indd 21 16-11-22 下午3:38 22 2. 开放性 在短短的两年半时间里,该客户已经选择了多个厂商的 PC 服务器用 于部署 Greenplum,包括 DELL、HP、IBM 等等,且在单个集群混合 了不同厂商不同型号的服务器。Greenplum 数据库在这些硬件上的表 现都很稳定。 开放性的特性给客户带来的好处,不只是硬件厂商和型号的选择范围, 也包含工程实施过程的便利性。20140 码力 | 64 页 | 2.73 MB | 1 年前3
