Abstract

Database systems use the journaling techniques in order to guarantee database consistency even at system crashes. Since the journaling needs duplicated write operations, it exhausts the lifetime of NAND flash-based storage device. In this paper, we propose a novel file system-level block remapping technique, which changes only the file system metadata at database checkpointing without any data write operations. Experiments show that the proposed scheme can reduce the write traffic on storage device by 17% on average.
