New hardware platforms, e.g. cloud, multi-core, etc., have led to
a reconsideration of database system architecture. Our Deuteron-
omy project separates transactional functionality from data man-
agement functionality, enabling a flexible response to exploiting
new platforms. This separation requires, however, that recovery
is described logically. In this paper, we extend current recovery
methods to work in this logical setting. While this is straightfor-
ward in principle, performance is an issue. We show how ARIES
style recovery optimizations can work for logical recovery where
page information is not captured on the log. In side-by-side per-
formance experiments using a common log, we compare logical
recovery with a state-of-the art ARIES style recovery implementa-
tion and show that logical redo performance can be competitive.
