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 ...

MapReduce: Simple data processing on large cluster

Here is a translation of the Redis Official document "A fifteen minute introduction to Redis data Types", as the title says, The purpose of this article is to allow a beginner to have an understanding of the Redis data structure through 15 minutes of simple learning. Redis is a kind of "key/value" type data distributed NoSQL database system, characterized by high-performance, persistent storage, to adapt to high concurrent application scenarios. It started late, developed rapidly, has been many ...

Lei and Mingzhu bet on the Internet people are excited for a while. Old Ji pay attention to the relevant comments, found that many "experts" are in analysis said Mingzhu will lose, and millet in five years of income certainly more than gree. These comments can not help but remind Old Ji once contacted a company, at that time the company has just come on the market, a few years before the listing of the performance that is rubbing against the multiply growth. Several senior executives are excited to die there, saying that we only have ten years, we can expect to exceed the old club xx, a yearly income of 100 ...

This paper is an excerpt from the book "The Authoritative Guide to Hadoop", published by Tsinghua University Press, which is the author of Tom White, the School of Data Science and engineering, East China Normal University. This book begins with the origins of Hadoop, and integrates theory and practice to introduce Hadoop as an ideal tool for high-performance processing of massive datasets. The book consists of 16 chapters, 3 appendices, covering topics including: Haddoop;mapreduce;hadoop Distributed file system; Hadoop I/O, MapReduce application Open ...

Hadoop RPC communication is different from other systems RPC communication, the author for the use of Hadoop features, specifically designed a set of RPC framework, the framework of personal feeling is still a little complicated. So I'm going to split into client-side and Server service-side 2 modules for analysis. If you have a good understanding of RPC's entire process, you must be able to understand it very quickly for Hadoop RPC. OK, let's cut to the chase. The related code for the RPC of Hadoop is ORG.APAC ...

The two questions in the previous section, "How do you determine intelligence?" and "Is the animal smart?" have been resolved.

In the field of telecommunications and it, a complete system consists of various kinds of basic physical resources and software resources, the basic physical resources provide computing, storage, network and other hardware capabilities, and all kinds of software constitute a variety of colorful applications. 　　These applications are developed by different manufacturers, based on different operating system platforms, using different software architectures, with different deployment patterns, the application of diversification will inevitably bring the complexity of software management. The software management described in this paper mainly refers to the lifecycle management of the software in the field, including the release of software, configuration management, distribution and deployment, patch management 、...
