MongoDB is a database based on distributed file storage. Written by the C + + language. Designed to provide scalable, high-performance data storage solutions for Web applications. Products between relational and non relational databases are among the most functionally rich and most like relational databases in relational databases. The data structure he supports is very loose and is a JSON-like Bjson format, so you can store more complex data types. MONGO the most characteristic is that he supports the query language is very powerful, its syntax is somewhat similar to the object-oriented query language, can almost actually ...

Research on load Balancing strategy of Distributed system South University Li Deng Although load balancing has been studied for nearly 20 years, the load balancing strategy is a NP complete problem, and the real satisfying system is not many. In this paper, the distributed system and distributed object technology are discussed, and then the algorithm and model of load balancing are studied in detail, and the reasons of extra cost are studied, and the difficulties in the research of load balancing strategy are researched. The innovation of this paper is to put forward the information center scheduling strategy, which is widely studied in the current typical load ...

Design and implementation of a file prefetching model oriented to Distributed File System Shi Ming Liu Yi Tangge How to provide stable and efficient file I/O performance for upper level application and computation, is the hotspot of distributed File system performance research. This paper analyzes the common characteristics of the Distributed file system in the design mechanism, and proposes a general heuristic document Prefetching model based on this, and selects the HDFs platform for system implementation. The heuristic file prefetching is transparent to the upper layer, adopts the method of establishing the prefetch thread pool in the file system, and takes the data storage file of the file block as the prefetch unit, in the Distributed File Department ...

Scalable distributed Relational Cloud database scheme Wang Minwudi Chong Zhu Zefei Li Renwang analyzing the base of various relational and database to meet the requirement of high concurrency and high availability of cloud database Based on the convenience and scalability of relational data, a scalable relational cloud database scheme is proposed. This scheme presents a new system architecture. Database read-write process data merging process data model and structure and storage and analyzing the bottleneck of its system architecture theory finally, the data consistency availability and online running performance are analyzed and the results show that this scheme ...

Slishan, deputy director of the new Energy and Renewable Energies Division of the National Energy Bureau, said April 6 in an interview with the first financial daily that the state Energy Bureau is currently studying the distribution of distributed energy development, and has issued a "distributed energy management measures" in the interior. At the same time, the National Energy Agency is studying specific power management and Internet price issues.　　By then, enterprises can do their own electricity generation, the excess power can be input into the grid.　　However, he disclosed that the "method" is currently in the consultation stage, will not be announced to the outside world in the near future. "Distributed energy" refers to the distribution of energy in the user side of the comprehensive ...

Research on distributed data stream clustering algorithm based on Hadoop mapreduce Cai Binlei Ningjiadong Zhu Shiwei Guo Qin with the continuous increase of data flow scale, the existing clustering algorithm based on grid has no effect on the clustering of data streams, can not find any shape clusters in real time, and can not delete the noise points in the data stream in time. This paper presents a distributed data stream clustering algorithm (Pgdc-stream) based on grid density in Hadoop platform environment, which facilitates the parallel clustering of data flow in MapReduce framework based on Hadoop.
