Research on HBase Loading data Feng Xiaope The Internet has made great progress today. Today, a huge amount of data is uploaded to the Internet. As the size of the data grows, a large number of business scenarios begin to consider the level of data storage expansion, allowing storage services to be added and deleted, while current relational databases are more focused on a single machine. The massive data storage becomes the bottleneck, the single machine cannot load the massive data. HBase is the Apache top open source project separated from Hadoop. Because it is a good Java implementation of the G ...

Data distribution and storage design of ship information System Wang Kanmei Hu Xiaohui Zhou Wenya Gao with the increasing requirements of data interaction between various systems of ships, the explosive increase of historical data, the efficient distribution of data and the increasing importance of mass data storage. On the basis of analyzing the specification of DDS (data distribution service), the Ship Information data distribution system is built, and a joint storage scheme based on RDB and NoSQL (not only SQL) is proposed. To realize the data of ship information system ...

Network latency has a significant impact on user satisfaction, and the physical distance between users and servers is the biggest factor in the latency problem. 　　Problems such as application and processing latency can always be solved by adding more computing resources, but long-distance data packets always take time (for example, from London to New York), which depends largely on the physical constants of the speed of light. Because most cloud computing providers are currently located in the United States, the problem of network latency in the American continent can be tolerated by users. But if your big one ...

Experimental analysis on computing performance of massive data based on GemFire Xu Xiang, Shiming, Lio, Zhu Yu in this paper, a distributed Memory database experiment platform based on GemFire is proposed for the real-time and dynamic scalability processing of high performance computation of multi-source dynamic mass data in traffic field. Using the key-value data storage structure and the distributed dynamic member relationship, the computational performance of the floating vehicle system is tested and analyzed by loading the real data of the float car in the whole cloud computing architecture. The experimental results show that the platform can shorten the computation time of tens above large data to 10 of the original system.

The U.S. Fireworks, Firearms and Bursting Control Agency (ATF) not only hopes to find out about the people by keyword, but also hopes to have a system that can search 18 generations of its citizens without using Facebook. According to a recent filing by ATF, the agency's strategic intelligence information division, OSII, wants to buy a large online data storage system and plans to have the system operate for at least five years. So that it can automatically search for individuals, and by combining "organizational and non-organizational data" to "detect 2 ...

A collaborative mechanism for computing and data in large data technology Wang Peng Huang Liu Fengan Handsome Data system is also known as a data-oriented high-performance computing system, similar to the traditional high-performance computing systems, and its computing and data storage is usually based on the cluster implementation of distributed systems. Based on the coordination mechanism of computation and data, this paper compares the high performance computing and data-oriented high performance computation, and points out that the cooperative mechanism of computing and data determines the basic structure and performance of large data system. The integration of Distributed file system and computation through assistance mechanism is the realization of automatic parallelization of large data system.

Cloud storage is an effective choice for a range of storage requirements. 　　Understanding the key features of various cloud storage systems helps identify the right use cases and avoids potential and costly errors. We use the term "cloud storage" as if there is a single data storage service. There are actually many types of cloud storage systems. These systems can be categorized by identifying the characteristics of the appropriate use cases. For example, you don't want to run an inventory management system using a filing system that takes hours to respond to a read request. Similarly, there is no reason to save for low latency SSD if disk-based storage is effective ...
