Security control heterogeneous big data cloud storage system based on adaptive cache

Abstract

Abstract In order to improve enterprise information security and the performance of storage system in data processing process, the application of adaptive memory cache mechanism in remote sensing data storage is studied. Firstly, alluxio is used to build a unified virtual file system, and the caching mechanism based on spatial relationship and historical data access inference is studied. Secondly, Presto based on memory computation is introduced as the storage component of remote sensing data meta-data, providing real-time read-write support for massive remote sensing data meta-data and advanced semantic information. Through experiments, the process of adaptive memory buffer remote sensing data storage system takes less time than the traditional storage method.
