Optimistic Replication in Pharos, a Collaborative Application on the Web
Pharos is a collaborative application which enables users to share document annotations. Annotations of a same subject are stored altogether in channels, and channels are replicated to improve performance. What characterises data replication in a collaborative application like Pharos is the way users see data. If, for instance, mutual consistency is required, then collaboration should be synchr...
متن کاملOptimistic replication in HOPE
The growing imbalance between network latency and throughput is causing nodes in distributed systems to appear to be moving farther apart. Many distributed systems are turning to replication as a mechanism to make resources appear closer. However, maintaining one-copy consistency in a system containing replicated elements has proven diicult. In particular, the checks required to make consistent...
متن کاملTowards On-Demand Web Application Replication
The increasing popularity of Web applications drives the need for systems that offer improve high performance web services by replicating applications at geographically distributed servers. In this paper, we propose a system for Web application replication that replicates both application code and its data. A key challenge in such a system is data replication and consistency, so that each repli...
متن کاملOptimistic-Preventive Replication in a Database Cluster
In a database cluster, preventive replication can provide strong consistency without the limitations of synchronous replication. However, the original proposal [11] and its extension to partial replication [3] have performance limitations: to prevent conflicts, transactions are forced to wait a delay time before executing. In this paper, we address this problem in order to scale up to large clu...
متن کاملReplication: Optimistic Approaches
optimistic, replication, survey Replication is a key enabling technology in distributed data sharing systems for improving both availability and performance. This paper surveys optimistic replication algorithms, which allow replica contents to diverge in the short term, in order to support concurrent work and to tolerate failures in low-quality communication links. The importance of such techni...
