Described is a system, method, and computer program product for performing elections in a database cluster, where system resource statistics information is used to predict a cluster node failure. Resource statistics data is classified and used to identify anomalies. The anomalies can be used to determine the probability of a cluster node failure and to then elect a new master node and/or surviving sub-cluster.

Method and system to implement cluster failure prediction to facilitate split brain resolution

Described is a system, method, and computer program product for performing elections in a database cluster, where cluster topology representations are distributed across the cluster nodes using a prioritized messaging protocol. The cluster topology representations may be implemented as connectivity bit-vector that provide information that identifies which nodes in the cluster are able to communicatively connect with other nodes.
