The presumed-either two-phase commit protocol
Gopi K. Attaluri, Kenneth Salem · IEEE Transactions on Knowledge and Data Engineering · 2002
This paper describes the presumed-either two-phase commit protocol. Presumed-either exploits log piggybacking to reduce the cost of committing transactions. If timely piggybacking occurs, presumed-either combines the performance advantages of presumed-abort and presumed-commit. Otherwise, presumed-either behaves much like the widely-used presumed-abort protocol.
