Generalization of the fast consistency algorithm to a grid with multiple high demand zones

摘要: One of the main challenges grid systems large scale and data intensive is that providing high availability performance, in spite unreliability delay occasioned by size Internet. Replication enables us to meet such a challenge with success. In context weak consistency, fast consistency algorithm prioritizes replicas demand. Nevertheless, only works well single zone demand, whereas multiple demand zones its performance poor. this paper, we propose an chosen according whereby each select leader subsequently construct logical topology, linking all together. way, changes are able reach without low forming barrier prevent from happening.
