The epoch will be incremented if the node's +config epoch is zero, or if it is less than the cluster's greatest epoch. + +**Note:** config epoch management is performed internally by the cluster, and +relies on obtaining a consensus of nodes. The `CLUSTER BUMPEPOCH` attempts to +increment the config epoch **WITHOUT** getting the consensus, so using it may +violate the "last failover wins" rule.
