这里有新鲜出炉的HBase教程,程序狗速度看过来!

HBase分布式面向列的开源数据库

HBase是一个分布式的、面向列的开源数据库,该技术来源于 Fay Chang 所撰写的Google论文“Bigtable:一个结构化数据的分布式存储系统”。就像Bigtable利用了Google文件系统(File System)所提供的分布式数据存储一样,HBase在Hadoop之上提供了类似于Bigtable的能力。HBase是Apache的Hadoop项目的子项目。HBase不同于一般的关系数据库,它是一个适合于非结构化数据存储的数据库。另一个不同的是HBase基于列的而不是基于行的模式。

HBase – Hadoop Database,是一个高可靠性、高性能、面向列、可伸缩的分布式存储系统,利用HBase技术可在廉价PC Server上搭建起大规模结构化存储集群。

HBase是Google Bigtable的开源实现,类似Google Bigtable利用GFS作为其文件存储系统,HBase利用Hadoop HDFS作为其文件存储系统;Google运行MapReduce来处理Bigtable中的海量数据,HBase同样利用Hadoop MapReduce来处理HBase中的海量数据;Google Bigtable利用 Chubby作为协同服务,HBase利用Zookeeper作为对应。
