SYSTEM AND METHOD FOR SUPPORTING RESETTABLE ACKNOWLEDGEMENTS FOR SYNCHRONIZING DATA IN A DISTRIBUTED DATA GRID

A system and method can support resettable acknowledgements for synchronizing data between clusters in a distributed data grid. The system can use one or more unique identifiers (IDs) to support message passing between different clusters in the distributed data grid. A first cluster can receive a first replication message from a second cluster, wherein the replication message indicates that the replication message is from a new cluster. Then, the system can reset the first cluster to preserve idempotence in possessing one or more replication messages that are received from the second cluster, following the first replication message.
