ABSTRACT:
An asynchronous peer-to-peer data replication method implemented within a replication cluster comprising at least one master node and at least a first client node includes entering an update in a data volume of the master node and storing the update in a master node storage. Next, updating a first active session in a master log and then sending a first message from the master node to the first client node. The first message comprises a first message content and first “piggybacked” data indicating that the first active session in the master log was updated. Next, receiving the first message by the first client node, registering that the first active session in the master log was updated and signaling internally that the first active session in the master log was updated. Next, sending an update request from the first client node to the master node, processing the update request by the master node and sending the update to the first client node. Finally, receiving the update by the first client node and updating the first active session in a first client log.
