Data replication in a distributed system: A performance study

[[abstract]]Investigates the performance issues of data replication in a loosely-coupled distributed database system, where a set of database servers are connected via a network. A database replication scheme called “replication with divergence”, which allows some degree of divergence between the primary and the secondary copies of the same data object, is compared to two other schemes that, respectively, disallow replication and maintain all replicated copies consistently at all times. The impact of some tunable factors, such as cache size and the update propagation probability, on the performance of “replication with divergence” is also investigated. These results shed light on the performance issues that were not addressed in previous studies on the replication of distributed database systems[[fileno]]2030204010044[[department]]資訊工程學
