Ali HBase ultra-detailed practice summary | One article to understand structured storage in the era of big data

Foreword Back in 2011, Hadoop, as a new thing, had already played well in Alibaba. Thousands of "cloud ladders" were the famous computing platform in China at that time.

This year, HBase, a good brother of Hadoop, was brought into Taobao by Master Bi Xuan and started its Ali journey. From the original Taobao historical transaction records to last year's Alipay consumption record storage and unified online historical storage; from the multi-year storage evolution of Ant Security Risk Control to the passionate iteration of HBase, TT, and Galaxy; HBase has experienced the bitterness of youth in Ali. , released the vitality of youth, but also paid the price of growth. With the unremitting efforts of several generations, the five-year-old HBase has begun to show a more mature, complete and richer side, and has become one of the widely used storage products within the company.

After the internal tempering of the Alibaba Group, the group will deliver this technological dividend to the majority of Alibaba Cloud customers. The cloud database HBase product has been launched, which supports massive PB-level big data storage and is suitable for high-throughput random read and write scenarios.

This article will systematically describe the positioning and construction ideas of HBase. The relevant content may not be in-depth development. There will be special introductions in the future. Please keep an eye on Ali technology-related articles.

Overview
HBase is an open source non-relational distributed database (NoSQL), based on Google's BigTable modeling, is a highly reliable, high-performance, highly scalable distributed storage system, using HBase technology can be built on cheap PC Server Large-scale structured storage clusters.

HBase was initially developed and constructed in the form of a Hadoop sub-project, and it was not until May 2010 that it officially became an independent development of Apache's top-level project. With the surging growth of data in the Internet era, HBase has been rapidly developed and applied as a basic storage system. A large number of well-known commercial companies (Facebook, Yahoo, Ali, etc.) have involuntarily joined the HBase ecological construction team and become one of the most active Apache communities. one.

The capabilities and characteristics of HBase can be briefly summarized in the following table. Based on these capabilities, it is widely used in the fields of online access to massive structured data, real-time computing of big data, and storage of large objects.
