Optimistic Replication and Resolution

نویسنده

  • Marc Shapiro
چکیده

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 (see entry on Eventual Consistency).

Optimistic Replication with Forward Conflict Resolution in Distributed Real-Time Databases

In this thesis a replication protocol – PRiDe – is presented, which supports optimistic replication in distributed real-time databases with deterministic detection and forward resolution of transaction conflicts. The protocol is designed to emphasize node autonomy, allowing individual applications to proceed without being affected by distributed operation. For conflict management, PRiDe groups ...

Deening and Measuring Connicts in Optimistic Replication

Optimistic replication is often viewed as essential for large scale systems and for supporting mobile computing. In optimistic replication, updates can be made concurrently to diierent le replicas, resulting in multiple versions of the le. To recover from these connicting updates, after-the fact connict resolution actions are required to recombine multiple versions into one. This paper deenes t...

Supporting Application-Specific Resolution in an Optimistically Replicated File System

In this position paper we describe an interface to incorporate application-specific knowledge for conflict resolution in an optimistically replicated file system. Conflicts arise in such systems because replicas of an object can be modified simultaneously in different network partitions. Application-specific knowledge is made available by the application writer in specialized tools called Appli...

A Simulation Framework for Evaluating Replicated Filing Environments

Optimistic replication of data is becoming increasingly popular in distributed systems. However, the performance characteristics of such systems are not well understood. We have developed a flexible and extensible simulation framework to investigate the operating costs and service quality of optimistic replication for file systems. This paper describes the simulator and presents the results of ...
