Distributed database systems use commit protocols to ensure atomicity in case of distributed transactions and a wide variety of commit protocols have been proposed so far. Two–phase commit (2PC) is a widely accepted standard protocol for distributed transactions. But 2PC suffer from blocking problem due to which three-phase commit (3PC) protocol was proposed which is an extension of 2PC. This paper present a review and comparison of commit protocols used for distributed database systems.
