Abstract This paper presents an updated version of Viewstamped Replication, a replication technique that handles failures in which nodes crash. It describes how client requests are handled, how the group reorganizes when a replica fails, and how a failed replica is able to rejoin the group. The paper also describes a number of important optimizations and presents a protocol for handling reconﬁgurations that can change both the group membership and the number of failures the group is able to handle.show more
Abstract We describe our experience in building a fault-tolerant data-base using the Paxos consensus algorithm. Despite the existing literature in the ﬁeld, building such a database proved to be non-trivial. We describe selected algorithmic and engineering problems encountered, and the solutions we found for them. Our measurements indicate that we have built a competitive system.show more
