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…

良心博文: http://blog.csdn.net/opennaive/article/details/7532589 这里只是基础简述 众人说: 链接:http://blog.csdn.net/opennaive/article/details/7532589 2006年的OSDI有两篇google的论文,分别是BigTable和Chubby. Chubby是一个分布式锁服务,基于Paxos算法: BigTable是一个用于管理结构化数据的分布式存储系统,构建在GFS.Chubby.SSTa…
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”…

HDFS(Hadoop Distributed File System ) HDFS(Hadoop Distributed File System )Hadoop分布式文件系统.是根据google发表的论文翻版的.论文为GFS(Google File System)Google 文件系统(中文,英文). 1. 架构分析 基础名词解释: Block: 在HDFS中,每个文件都是采用的分块的方式存储,每个block放在不同的datanode上,每个block的标识是一个三元组(block id, n…

You are given several logs that each log contains a unique id and timestamp. Timestamp is a string that has the following format: Year:Month:Day:Hour:Minute:Second, for example, 2017:01:01:23:59:59. All domains are zero-padded decimal numbers. Design…
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…
