Abstract
A method implemented by a node in a high availability system having a master node and a replica node, the method including monitoring another node to determine whether or not the node is responding via a network connection, when the node is found to be not responding, changing into a periodic replication mode of operation, serving user requests while in the replication mode of operation, determining that the other node is now responding via the network connection, negotiating to merge changes resulting from serving the user requests with the other node, and reverting to an online replication mode of operation.
