This paper presents a vector data access method in memory, aimed at improve the I/O performance bottleneck in spatial data analysis. It uses memory copy instead of data interaction between disk and memory, as the memory copy operation is much faster than disk. It designs the vector spatial data model in memory as K-V structure, and presents the data access method between memory and SIC type. The experiment...
This paper concentrates on reducing the cost of I/O and improving algorithm efficiency by designing and realizing a spatial data access system based on main memory database (MMDB). We use Redis to manage vector spatial data in main memory which is faster than hard disk or disk-based database in respect of data access. We design a management strategy of spatial data, internal and external data exchange...
