Abstract

Aiming at solving the problem that rapid increase of time delay in data synchronization within existing mimic storage architecture, which leads to the performance degradation during system security scheduling, this paper proposed a pre-synchronization model that enabled standby executors to utilize checkpoints in heterogeneous pools for data pre- synchronization, thereby reducing the time required for the executor to go online. Furthermore, according to the synchronization characteristics of the pre-synchronization model and the switching scheduling situation, this paper designed CMEC method. This method could determine the optimal checkpoint interval by maximizing the effective work rate of each execution cycle, balancing checkpoint overhead and rollback overhead. The experiments show that, compared with the existing full-volume synchronization strategy, this method shortens the synchronization time required for the executor to go online, improves the synchronization efficiency and ensures the stability and continuity of the system under increasingly heavy business loads.
