Immortal DataBase (DB) is a transaction time database system that is built into a commercial database system rather than being layered on top. This enables it to have performance that is very close to the performance of an unversioned current time database system. Achieving such competitive performance is essential for wide acceptance of this temporal functionality. In this paper, the authors describe further performance improvements in two critical dimensions. Immortal DB range search performance is improved for current time data via improved current version storage utilization, making this performance essentially the same as unversioned performance.
