Description: bigtable是设计来分布存储大规模结构化数据的，从设计上它可以扩展到上２^50字节，分布存储在几千个普通服务器上．Ｇoogle的很多项目使用ＢＴ来存储数据，包括网页查询，google earth和google金融．这些应用程序对ＢＴ的要求各不相同：数据大小（从URL到网页到卫星图象）不同，反应速度不同（从后端的大批处理到实时数据服务）．对于不同的要求，ＢＴ都成功的提供了灵活高效的服务．在本文中，我们将描述ＢＴ的数据模型．这个数据模型让用户动态的控制数据的分布和结构．我们还将描述ＢＴ的设计和实现．

Description: Google的核心竞争技术是它的计算平台。Apache上就出现了一个类似的解决方案，目前它们都属亍Apache的Hadoop项目，对应的分删是： Chubby-->ZooKeeper GFS-->HDFS BigTable-->HBase MapReduce-->Hadoop 目前，基亍类似思想的Open Source项目迓径多，Hadoop是其中最为流行的框架，本文就将简要介绍hadoop的一个开发流程。-Hadoop got its start in Nutch. A few of us were attempting to build an open source
web search engine and having trouble managing computations running on even a
handful of computers. Once Google published its GFS and MapReduce papers, the
route became clear. They’d devised systems to solve precisely the problems we were
having with Nutch. So we started, two of us, half-time, to try to recreate these systems
