Column-oriented storage has become a progressive model for high-speed database systems and flash memory has become a critical storage in building high-performance servers. In this paper, the authors analysis traditional raw-oriented storage model and then propose a new column-aware storage model using flash memory and an assist drive to improve the effective performance of the high-speed column-oriented database system. Their storage management scheme called column-aware polarization improves the performance of update operation by classifying each column into highly compressive or lowly compressive, and balancing overloaded update operations under heavy workload condition.
