Abstract

Fast spatial query is the foundation of the mass ZY1-02C data application. In the traditional spatial query structure using relational database, frequent disk I/Os and data swaps degrade the query performance a lot. In contrast, main memory database which is completely based on the memory can significantly improve the searching efficiency. In this study, a vector data storage and R-tree indexing structure was designed and implemented based on the Redis database, which is a main memory database of Key-Value type. This structure was used in practice and the efficiency of spatial query was improved.
