hours to 8 seconds, while MkI's genetic analysis time has been shortened from a few days to 20 minutes.Here, let's look at the difference between MapReduce and the traditional distributed parallel computing environment MPI. MapReduce differs greatly from MPI in its design purpose, usage, and support for file systems, enabling it to be more adaptable to processing needs in big data environments.What new met
Big Data Network Design essentialsFor big data, Gartner is defined as the need for new processing models for greater decision-making, insight into discovery and process optimization capabilities, high growth rates, and diverse information assets.Wikipedia is defined as a collection of
The authors of this book describe each design pattern by using a class diagram (the UML class diagrams, the basics of which are described in addition to the object-oriented language applet + character dialogue interpretation knowledge points. This article is the introduction of "Big talk design mode" used in the object-oriented basic knowledge (based on C # language), easy to read the book code.

Analysis of the Reason Why Hadoop is not suitable for processing Real-time Data1. Overview
Hadoop has been recognized as the undisputed king in the big data analysis field. It focuses on batch processing. This model is sufficient for many cases (for example, creating an index for a webpage), but there are other use mod
overload the protected function, such as issplitable (), which is used to determine whether you can slice a block and return it by default to true, indicating that as long as the data block is larger than the HDFS block size, Then it will be sliced.But sometimes you don't want to slice a file, such as when some binary sequence files cannot be sliced, you need to overload the function to return FALSE.
