An adaptive replica consistency maintenance mechanism in cloud storage
Wang Ximei Yang Shoubao Sherry Guo Liangmin
An adaptive replica consistency maintenance mechanism based on application and user requirements is proposed, which includes updating consistency and merging consistency. The system adjusts the consistency mechanism according to the formal consistency demand, achieves the dynamic balance between the replica consistency, usability and system performance. The experimental results show that This mechanism can significantly reduce the operating cost and improve the availability of replicas in the case of consistency requirements.
