【摘要】 近年来,由于Hbase适用于海量半结构化和非结构化数据存储,伸缩性较好,受到越来越多企业的青睐,但是当检测用户访问权限时,HBase细分到了表中某些列,在列的数量较多的情况下,它的实时访问权限检测效率不理想。从叠加树的角度,基于列编码通过搜索树中叶节点的方式来获取访问权限,在保证安全性的情况下,减少了搜索时间的开销。更多还原

【Abstract】 In the case of a large number of columns,its real-time access permission detection efficiency is not satisfactory.From the perspective of the overlay tree,this paper obtains the access rights by searching the leaf nodes in the tree based on the column coding.When the security is ensured, the search time overhead is greatly reduced.更多还原
