System and method for supporting data grid snapshot and federation

Abstract:

A system and method can support federation replication in a distributed computing environment. The system can provide one or more federation replication channels between a plurality of members in a first cluster and a plurality of members in a second cluster. Furthermore, a replication request can be transmitted from a federation coordinator to the plurality of members in the first cluster, wherein each said member in the first cluster owns a set of partitions. Then, the aggregated data for each said partition in the first cluster can be sent to the plurality of members in the second cluster via said one or more federation replication channels. Additionally, using the second cluster, the system can take a persistent snapshot of information on the plurality of members in the first cluster while the first cluster is operational.
