For the business staff, especially the data scientists, Informatica's intelligent data platform is not only an intelligent large data preprocessing tool, but also can bring direct value to the enterprise as the business system. Internet companies often emphasize the details and micro-innovation, the product of a certain function to the extreme, so as to firmly attract a large number of users. But enterprise-class vendors are different, preferring to platform their products. The advantage of the platform is that you can integrate as many functions as possible to facilitate the department ...

In Google data centers there are large numbers of data to be processed, such as a lot of Web pages crawled by web crawlers (WebCrawler). 　　 　　Since many of these data are PB levels, the process has to be as parallel as possible, and Google has introduced the MapReduce distributed processing framework to address this problem. The technology overview MapReduce itself originates from functional languages, mainly through "map" and "Reduce" ...

MapReduce: Simple data processing on large cluster

Foreword in the first article of this series: using Hadoop for distributed parallel programming, part 1th: Basic concepts and installation deployment, introduced the MapReduce computing model, Distributed File System HDFS, distributed parallel Computing and other basic principles, and detailed how to install Hadoop, How to run a parallel program based on Hadoop in a stand-alone and pseudo distributed environment (with multiple process simulations on a single machine). In the second article of this series: using Hadoop for distributed parallel programming, ...

Now the investment community has focused on projects such as mobile Internet applications, internet finance and smart-wear devices, which appear to be pigs in a number of outlets. Undeniably, in the Internet and traditional industries constantly penetrate into the depth of the present, each of these projects to promote, will change people's life, are an immeasurable blue sea. But the odd thing is that a lot of reserves, when rich in gold, are just flashing in the torrent of time ahead, and then buried by a din and doubt. This gold mine, which I will elaborate and excavate, is a pig that can really fly ——...

Hadoop is a Java implementation of Google MapReduce. MapReduce is a simplified distributed programming model that allows programs to be distributed automatically to a large cluster of ordinary machines. Just as Java programmers can do without memory leaks, MapReduce's run-time system solves the distribution details of input data, executes scheduling across machine clusters, handles machine failures, and manages communication requests between machines. This ...

In recent years, with the emergence of new forms of information, represented by social networking sites, location-based services, and the rapid development of cloud computing, mobile and IoT technologies, ubiquitous mobile, wireless sensors and other devices are generating data at all times, Hundreds of millions of users of Internet services are always generating data interaction, the big Data era has come. In the present, large data is hot, whether it is business or individuals are talking about or engaged in large data-related topics and business, we create large data is also surrounded by the big data age. Although the market prospect of big data makes people ...

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 distributed features of the NoSQL database ...
