Lock technology is important to ensure transaction isolation, but if multi-tenant database continues to use traditional fixed granularity database lock, it will bear a very high burden. In this paper, to satisfy requirements in the shared storage multi-tenant database, we propose variable granularity lock (VGL) mechanism. It provides a lock of one granularity for each tenant who uses the shared storage multi-tenant database. In addition, we give experiments indicating that the performance of VGL is excellent.
