There are two main ways to store data: Database and filesystem, and the object-oriented storage are developed behind, but the overall thing is to store both structured and unstructured data. DB is initially serviced for structured data storage and sharing. FileSystem storage and sharing is large files, unstructured data, such as pictures, documents, audio and video. With the increase in data volume, stand-alone storage can not meet the needs of structured and unstructured data, then in the era of cloud computing, there is a distributed ...

"Editor's note" ebay opens up a database technology called Kylin, and ebay shared many of the details of Kylin on a Wednesday blog, providing SQL interfaces and OLAP interfaces based on Hadoop, supporting terabytes to petabytes of data, Kylin is designed to reduce the query latency of Hadoop at more than 1 billion rows of data levels. All this shows that ebay has made good progress in using Hadoop technology. Below: Online auction website ...

Hadoop is a large data distributed system infrastructure developed by the Apache Foundation, the earliest version of which was the 2003 original Yahoo! Doug cutting is based on Google's published academic paper. Users can easily develop and run applications that process massive amounts of data in Hadoop without knowing the underlying details of the distribution. The features of low cost, high reliability, high scalability, high efficiency and high fault tolerance make Hadoop the most popular large data analysis system, yet its HDFs and mapred ...
