Abstract: Data replication places physical copies of a shared logical item onto different sites. Optimistic replication (OR) allows a program at some site to read or update the local replica at any time. An update is tentative because it may conflict with a remote update. Such conflicts are resolved after the fact, in the background. Replicas may diverge occasionally but are expected to converge eventually.

A Projection-Stable Grammatical Model for the Distributed Execution of Administrative Processes with Emphasis on Actors' Views
Milliam Maxime Zekeng Ndadji,Maurice Tchoupé Tchendji,Clémentin Tayou Djamegni,Didier Parigot +3 more
TL;DR: In this paper, the authors present a model for a completely decentralized and artifact-centric execution of administrative processes specified using LSAWfP, which allows the confidential execution of certain tasks by ensuring that, each actor potentially has only a partial perception of the processes' global execution states.

Time, clocks, and the ordering of events in a distributed system
TL;DR: In this article, the concept of one event happening before another in a distributed system is examined, and a distributed algorithm is given for synchronizing a system of logical clocks which can be used to totally order the events.

Disconnected operation in the Coda File System
TL;DR: This paper shows that disconnected operation is feasible, efficient and usable by describing its design and implementation in the Coda File System by showing that caching of data, now widely used for performance, can also be exploited to improve availability.

Optimistic replication
Yasushi Saito,Marc Shapiro +1 more
TL;DR: This article identifies key challenges facing optimistic replication systems---ordering operations, detecting and resolving conflicts, propagating changes efficiently, and bounding replica divergence---and provides a comprehensive survey of techniques developed for addressing these challenges.

TL;DR: The motivation for and design of these mechanisms for conflict detection and per -write conflict resolution based on client-provid ed procedures are presented and the experiences gained with an initial implementation of the system are described.
