SYSTEM AND METHOD FOR SUPPORTING FAILOVER DURING SYNCHRONIZATION BETWEEN CLUSTERS IN A DISTRIBUTED DATA GRID

摘要

A system and method can support failover during synchronization between autonomous clusters in a distributed data grid. The system allows a cluster member in a source cluster to take over as an owner of a partition in a source cluster, when another cluster member in the source cluster becomes unavailable. Then, a cluster member in the destination cluster can receive one or more replication messages from said cluster member in the source cluster, wherein said one or more replication messages include one or more data changes. Furthermore, the cluster member in the destination cluster may ignore said one or more replication messages, if said one or more replication messages have already been received and successfully processed in the destination cluster.

1. A method for supporting federated data in a distributed data grid, comprising:
allowing a cluster member in a source cluster to take over as an owner of a partition in a source cluster, when another cluster member in the source cluster becomes unavailable; receiving, via a cluster member in the destination cluster, one or more replication messages from said cluster member in the source cluster, wherein said one or more replication messages include one or more data changes; and ignoring, via the cluster member in the destination cluster, said one or more replication messages, if said one or more replication messages have already been received and successfully processed in the destination cluster.
