摘要
现如今,科技发展速度不断加快,云存储效率在先进科技的带动下大大提高,但云存储文件系统应用期间受静态完全副本冗余机制影响较大,这在一定程度上会增加云存储负载压力,最终影响系统运行稳定性,减慢系统运行速度。文章首先简要介绍RS纠删码,然后针对HDFS完全副本与纠删码对比分析,最后重点探究RS纠删码基础下HDFS云存储动态副本策略。
Nowadays, the scientific and technological development is being accelerated, and the efficiency of cloud storage isgreatly improved by advanced science and technology. However, the redundant mechanism of static full replica greatly affects the ap-plication of cloud storage file system. To some extent, this will increase the cloud storage load pressure, and ultimately affect the sta-bility of the system and slow down the speed of the system. This paper first briefly introduces RS erasure codes, then comparesHDFS full replica with erasure codes, and finally focuses on the dynamic replication strategy of HDFS cloud storage based on RSerasure codes.
