| Abstract(in English) | Driven by the ever-increasing demand of decision-making applications, database volume continues to grow, leading to prolonged query execution. Although parallel database systems are widely deployed for such analytical purposes, numerous components of nodes and storage cause failures during execution with non-negligible probabilities. The trivial approach of restarting entire queries can impose unacceptable temporal costs. In this paper, we propose a method that enables shared-storage parallel database systems to resume analytical queries by having back-up nodes take over pre-failure execution states that have been tracked and replicated among nodes. We also present several performance models of the mechanism and discuss its effect. |
