基于行键的 HBase 大数据文件存储 转换与快速检索研究.

In traditional and relational database, it is difficult to meet the needs of data storage and quick retrieval due to such huge amount of data. For this problem, this paper studied the mapping model of data file field, the relationship between data file field and HBase column, and the importing execution plan, which had solved the heterogeneity of file object and the universality of storage transformation. It put forward the "RowKey" generation rules and algorithm, and provided the algorithm of data transformation based on mapping model and "RowKey". Then according to the mapping rules of data file fields with HBase table column, the data in data file was transformed into HBase. It realized the fast data access and retrieval according to prefix matching in "RowKey" or keyword matching, which had strong commonality and could be widely used in HBase large data storage applications.
