Abstract: A sequence of configuration-delta messages from a configuration manager of a replication graph established for replicating state information of an application is received at a particular node of the graph. Representations of the messages are stored in a local configuration change repository. Using the repository, the node identifies neighbor source nodes and destination nodes of the graph. Subsequent to receiving a particular configuration-delta message indicating that a neighbor source node has been removed from the graph, a different source node is identified by the particular node, and a request is sent to the different source node to transmit a set of state transition messages pertaining to the application.
