All Implemented Interfaces:

DataSerializable, RemotePropagatable<Operation>

public class CacheReplicationOperation
extends AbstractOperation

Replication operation is the data migration operation of CacheRecordStore.

Cache record store's records and configurations will be migrated into their new nodes. Steps;

• Serialize all non expired data.
• Deserialize the data and config.
• Create the configuration in the new node service.
• Insert each record into ICacheRecordStore.

Note: This operation is a per partition operation.
