Survey of Big Data Storage Technology

摘要

Big data storage is the foundation of big data processing and analysis. By researching and summarizing main processing technology of data storage, this paper respectively investigates and analyzes the following four aspects: distributed file system, NoSQL database, database appliance and new-type data storage technology of MPP architecture. In addition, this paper gives some recommendations applicable to different environments in favor of grasping the development states of data storage technology from different angles. This paper summarizes file segmentation, appropriate scenarios and merits and faults of distributed file system, and mainly analyzes and summarizes the theories and appropriate scenarios of four data storage models of NoSql database. Furthermore, this paper investigates and concludes the developments and features of database appliance minutely. At the same time, outline MPP (Massively Parallel Processing) architecture, a new data storage technology. At last, the research trends of storage technology are prospected, providing references to the research of big data storage technology.
