随着 BI (DW) 在各个企业中重要性的不断提升,各个数据库厂家都希望能搭上这辆班车。这不,MySQL 也联合 Infobright 一起推出了开源的 数据仓库解决方案,而且是开源的。

其实现的各种DW该有的功能就不多说了,但是 Infobright 有一点非常吸引人的技术特点不能不提,那就是以列为导向的架构设计。

以列为导向的架构设计是非常适合于DW应用场景的,对于大多数DW的分析场景中,实际关注的数据很多时候都只有那么一列或者少数几列的数据。所以在以列为导向的设计中,大部分的分析查询都只需要读取某一个(或者几个)表的几列,而不需要像传统以行为导向的数据库(或者存储引擎)那样需要扫描整个表的数据,这两者IO量的差距是非常大的。除了以列为导向的架构设计之外,Infobright 和很多其他的DW解决方案一样,也会进行数据压缩,而且由于其以列为导向的存储方式,压缩比率在很多情况下都会比以行为导向的存储方式更高,效果更理想。有人通过测试比较,常规的以行为导向的存储数据压缩比率较高的时候也就 3:1 左右,但是 Infobright 的却很容易就做到 10:1 的压缩比率。

此外,从MySQL 以及 Infobright 的官方报道中除了上述技术特点(或者说优势)之外,还有很多其他的被描绘的非常神奇的功能,如被称为 “知识网格” (Knowledge Grid) 的自我管理功能,完全不需要索引或者分区,神奇的自我查询优化器等等。

这里是官方给出的一张 Infobright 的架构图:
