Abstract

Experiments conducted on a database testbed at Princeton indicate excessive page-table I/O is the major performance drawback of shadow recovery. In light of this, a method for parameterizing shadow recovery that minimize page-table I/O without sacrificing to much disk utilization is proposed. Using a simple model, the mechanism is analyzed and evaluated, comparing it to two conventional ones.
