The scalability of the system is the main reason for promoting the development of NoSQL movement, including distributed system coordination, failover, resource management and many other features. That makes NoSQL sound like a big basket that can be stuffed with anything. Although the NoSQL movement does not bring fundamental technological changes to distributed data processing, it still leads to extensive research and practice on protocols and algorithms. It is through these attempts to gradually summarize some effective database construction methods. In this article, I will focus on the NoSQL database distributed special ...

The intermediary transaction SEO diagnose Taobao guest Cloud host technology Hall is well-known, in the domestic Internet will encounter a variety of different man-made network failures, so that we can not normally visit many websites. However, because many people are not familiar with the network, many times will not be able to distinguish between different network failures, resulting in clearly network failure, but that is a server failure, or obviously a server failure, but it is considered a network failure situation. 　　I think it is necessary to explain the characteristics of different network failures, and how to differentiate them and solve them. In the domestic Internet environment, we often encounter ...

Using Lzo compression algorithms in Hadoop reduces the size of the data and the disk read and write time of the data, and Lzo is based on block chunking so that he allows the data to be decomposed into chunk, which is handled in parallel by Hadoop. 　　This feature allows Lzo to become a very handy compression format for Hadoop. Lzo itself is not splitable, so when the data is in text format, the data compressed using Lzo as the job input is a file as a map. But s ...

Original: http://hadoop.apache.org/core/docs/current/hdfs_design.html Introduction Hadoop Distributed File System (HDFS) is designed to be suitable for running in general hardware (commodity hardware) on the Distributed File system. It has a lot in common with existing Distributed file systems. At the same time, it is obvious that it differs from other distributed file systems. HDFs is a highly fault tolerant system suitable for deployment in cheap ...
