Wechat MomentsThe fusion policy protects the upstream services in the cluster from being overstressed, in the event that some nodes in the cluster crash completely without our knowledge. The system uses anomaly detection to complete the fusion function, by periodically and dynamically detecting anomalies in the upstream cluster to determine if some hosts are abnormal, and if anomalies are found, the hosts are isolated from the connection pool, this is called outlier detection.
