摘要 认为在大数据时代,数据迁移已成为以数据为中心的挖掘分析操作的基础环节。通过对大数据存储系统中的数据迁移进行需求分析,首先提出了数据迁移模型,并分析了影响迁移性能的因素;然后基于上述模型,从作业层面提出一种负载均衡的数据迁移算法。该算法能够规避数据访问热点,提高数据迁移效率。 In the big data era, data migration has become the basis for data centric mining analysis. In this paper, we analyze the requirements of data migration in big data storage systems and propose the corresponding migration model. We then analyze the factors affecting the migration performance. Then, using our proposed model, we design a load balanced migration algorithm from the aspect of job level,which can efficiently improve migration performance through avoiding data retrieving hotspots.
