Class CacheReplicationOperation

java.lang.Object

com.hazelcast.spi.Operation

com.hazelcast.spi.AbstractOperation

com.hazelcast.cache.impl.operation.CacheReplicationOperation

All Implemented Interfaces:

DataSerializable

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.
