Abstract

One method, by a first standby node, comprises monitoring communications from a first cluster leader, wherein the first cluster leader and the first standby node are members of a replicated state cluster; obtaining a designation as a second cluster leader of the replicated state cluster in response to the first cluster leader becoming unavailable; and assessing a state of an additional standby node of the replicated state cluster within a time period after the designation, wherein the additional standby node is available as a candidate leader of the replicated state cluster during the time period when the state of the additional standby node is valid based on one or more validity criteria, wherein the state comprises one or more results of one or more write operations generated by an application.
