Abstract
Data replication is to improve availability and performance in distributed systems and database systems. But it is difficult to keep strict consistency in data update. Existing protocols guarantee strict consistency, but the problem is that they need much cost and time delay. In this paper, hybrid update protocol permitting eager update for original copy and lazy update for other copies in propagation will be introduced. Hybrid update protocol also permits group update in ownership. This protocol manages replica version controls for group update consistency. By combining eager and lazy update with group ownership, it is to improve consistency and performance. Simulation shows it improves transaction throughput and turnaround depending on the application and situation.
