A Dynamic Management Mechanism Based on H-Index Secondary Indexes

摘要

Hbase is a kind of non-relational database providing scalable technology methods and platform for managing big data, but it can only query through the primary key. This paper proposes a secondary index mechanism based on the heat value which derives from H-Index, a secondary index scheme of Huawei. It updates data regularly by tagging heat values of data on the secondary index, then it gets heat values together and combines with secondary index read caching strategies to improve query performance. Experimental results show that the proposed mechanism can reduce the average response time for data query.
