摘要： 当Redis集群发生单点故障时,恢复过程不稳定且耗时较长。为此,在不增加网络传输代价的前提下,使用通信负载均衡的方法,对Redis集群容错机制的通信过程进行优化,从而达到提升集群可靠性的目的。实验结果表明,优化后的Redis集群的宕机恢复效率明显提升,在保证吞吐率和不提高传输代价的情况下,可提升集群处理故障状态的可靠性。

Abstract: It takes long time to recover when a single point of failure occurs in Redis cluster and the recover process is very unstable.This paper improves the communication process of the fault tolerance system in Redis cluster based on the consideration of load balancing without increasing the transmission cost of the system,on the purpose of improving the reliability of the cluster.Experimental results show that this method has a great improvement on the reliability and failover effectiveness of Redis cluster,under the premise that it does not cause much impact on the network transmission cost and throughput of the cluster,and indirectly enhances the reliability of cluster processing fault state.

Key words: Redis cluster, single node failure, fault tolerance mechanism, reliability, communication load balancing
