Hbase Data Model Design

After Facebook abandoned Cassandra, HBase 0.89 was given a lot of stability optimizations to make it truly an industrial-grade, structured data storage retrieval system. Facebook's Puma, Titan, ODS time Series monitoring system uses hbase as a back-end data storage System. 　　HBase is also used in some projects of domestic companies. HBase subordinate to the Hadoop ecosystem, from the beginning of the design of the system is very focused on the expansion of the dynamic expansion of the cluster, load are ...

HBase is a distributed, column-oriented, open source database based on Google's article "Bigtable: A Distributed Storage System for Structured Data" by Fay Chang. Just as Bigtable takes advantage of the distributed data storage provided by Google's File System, HBase provides Bigtable-like capabilities over Hadoop. HBase Implements Bigtable Papers on Columns ...

Sometimes the best way to learn about a software product is to see how it is used. It can solve what problems and how these solutions apply to large application architectures that can tell you a lot. Because HBase has a lot of open product deployments, we can do just that. 　　This section describes in detail some of the scenarios in which people successfully use HBase. Note: Do not limit yourself to the belief that hbase can only solve these usage scenarios. It is a nascent technology, and innovation based on the use of the scene is driving the development of the system. If you have new ideas, think you can benefit from HBAs ...

HBase provides both scalability and the economics of sharing the same infrastructure as Hadoop, but does its flaws rip off its hind legs? 　　The NoSQL expert laid out the debate frame. HBase is part of the world's most popular large data-processing platform, Apache Hadoop, modeled after Google BigTable. 　　But can this lineage guarantee hbase a dominant role in the competitive and fast-growing NoSQL database market? Michael of the MAPR company.

HBase is a column-oriented distributed database. HBase is not a relational database, and its design goal is to solve the limitation of the theory and implementation of relational database in processing massive data. The traditional relational database was designed for the trading system in the 70 's to satisfy the data consistency (ACID), and did not consider the scalability of data scale expansion, and the reliability of single point system failure. Although after many years of technical development, has produced some to the relational database patching (parallel database), however is limited by the theory and the realization about ...

Research on the construction of medical and health data center based on HBase and the synchronization of heterogeneous database Fang Shiwei to determine the data model, this paper puts forward the idea of HBase C-o-r modeling based on the E-R modeling of relational database, Then comprehensive analysis of Health department promulgated medical and Health metadata standards and the actual situation of some health institutions to achieve health information HBase Data Center construction. In order to realize the synchronization of data transparently to data center in heterogeneous relational database of medical institutions, the following schemes are proposed. First of all, in the data format proposed heterogeneous database production ...

Type selection and design of bigtable NoSQL database release time: 2012.04.16 14:20 Source: Blog Author: Blog This paper introduces the selection strategy and schema design principle of Bigtable/hbase type NoSQL database system. Data scale BigTable Class database system (Hbase,cassandra, etc.) is to solve ...

Several articles in the series cover the deployment of Hadoop, distributed storage and computing systems, and Hadoop clusters, the Zookeeper cluster, and HBase distributed deployments. When the number of Hadoop clusters reaches 1000+, the cluster's own information will increase dramatically. Apache developed an open source data collection and analysis system, Chhuwa, to process Hadoop cluster data. Chukwa has several very attractive features: it has a clear architecture and is easy to deploy; it has a wide range of data types to be collected and is scalable; and ...

Taxis, buses, passenger buses, heavy goods vehicles ..., operating vehicles occupy an important position in urban traffic, and people's lives and even social development has an important relationship. 　　It has become an indispensable part of intelligent traffic construction to build an information platform, monitor and manage the operating vehicles, standardize the vehicle behavior and establish a good operation order. "National Transportation Supervision Service Platform" is one of the important products developed by Beijing Zhong Xing Road Information Technology Co., Ltd. (hereinafter referred to as "Zhong Xing Lu"), which is committed to the monitoring, management and information interaction of the national freight vehicle, in full ...

Recently focused on Hadoop, so I've also been looking at Hadoop related projects.        HBase is an Open-source project based on Hadoop and an implementation of Google's bigtable. What is BigTable? Google's monitors the full explanation. Literally is a big table, in fact, and we imagine the traditional database table is still somewhat different. Loose data can be said to be between M ...
