TITLE: Instant Recovery from System Failures

ABSTRACT:
Abstract: Theory and techniques for single-page failures also enable efficient recovery from system failures. Traditional implementations permit new database transactions only after all recovery activities are complete, which may take minutes or possibly hours. Differently than advanced techniques by Mohan and by Speer and Kirchberg, which give early access only to pages not modified for a long time, instant restart permits immediate access to the pre-crash working set, including pages updated just prior to the failure. Differently than all previous recovery techniques, new transactions guide the recovery, not scans of the recovery log.

BIO:
