Research on the Metadata Storage Mode and Efficiency of Distributed File System Based on HGML

Abstract:

In the G / S mode, in order to meet the storage demands of massive spatial data, the requirements of the distributed file system (DFS) on back-end servers are extremely high. As one of the core tasks of DFS, the metadata storage is the necessary premise which ensures the reliability and efficiency of the entire system. This paper introduces a metadata storage mode based on HGML, and then designs and implements two solutions, which are scattered storage and integrated storage. According to the different characteristics of the two solutions, access efficiency of the metadata has been tested respectively. The result shows that the new metadata storage mode can basically satisfy the storage demands of massive spatial data.
