Abstract: In view of the node downtime caused by malicious attack in a distributed cluster,the recovery efficiency of the snapshot mechanism of traditional node restart is insufficient.Based on the storage and transmission of snapshot files by cluster nodes,a Raft-based snapshot dual-trigger strategy is proposed to improve the rationality of snapshot triggering.Experiments show that the algorithm improves the time from node downtime to recovery compared to the original Raft algorithm,so as to avoid the shortcomings of traditional cluster node recovery,and can better adapt to the complex network conditions of the cluster.Cluster node failure recovery is of great reference significance.
