Abstract Introduction::  Bigtable设计主旨:可扩地扩展到pByte级别和数千台机器的系统, 通用.可伸缩.高性能.高可用性.  不实现完整的关系数据模型,而是支持一个可以动态控制,允许用户自解释数据属性:  用户甚至可以指定数据(使用时)是存在内存中还是磁盘中:  支持row级别的事务处理:不支持跨行事务:: 2. Data model数据模型:三位数据模型: row.column.timestamp.row:即数据的key,是任意字符串(其实不一定要求是“字符”…

2006 年10 月Google 发布三架马车之一的<Bigtable:A Distributed Storage System for Strctured Data>论文之后,Powerset 公司就宣布 HBase 在 Hadoop 项目中成立,作为子项目存在.后来,在2010 年左右逐渐成为 Apache 旗下的一个顶级项目.可能是实际应用中包装得太好,很多人对于 HBase 的认识止步于 NoSQL .今天,蚂蚁金服的南俊从基础开始讲起,希望有助于增强大家在实际业务中对 HBase 的…

I researched a lot about storage system classes given at good universities this year. This had two reasons: The first was thispost of a researcher at NetApp, about the missing of a good storage or file system class book and secondly our own storage s…

The Hadoop Distributed File System (HDFS) is designed to store very large data sets reliably, and to stream those data sets at high bandwidth to user applications. In a large cluster, thousands of servers both host directly attached storage and execu…

Facebook在OSDI 2014上发表论文f4: Facebook's Warm BLOB Storage System,这个系统主要目的就是降低存储成本,在容忍磁盘,主机,机架,数据中心的同时提供2.1倍的存储因子(用户存储的1bit数据实际上占用磁盘2.1bit空间).本文只讨论f4系统的核心Erasure Code部分,如何降低存储因子. Facebook热的blob数据依然存在Haystack中,访问不那么频繁的数据(Warm)放入存储系统f4中.Haystack存储blob的思路就…
