Class CacheReplicationOperation

java.lang.Object

com.hazelcast.spi.Operation

com.hazelcast.cache.impl.operation.CacheReplicationOperation

All Implemented Interfaces:

DataSerializable, IdentifiedDataSerializable

public class CacheReplicationOperation
extends Operation
implements IdentifiedDataSerializable

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.

prepare

public final void prepare(CachePartitionSegment segment,
                          Collection<ServiceNamespace> namespaces,
                          int replicaIndex)

storeRecordsToReplicate

beforeRun

public void beforeRun()
               throws Exception

Description copied from class: Operation

The beforeRun is called before either the Operation.run() or the Operation.call() method is called. runs before wait-support

Overrides:

beforeRun in class Operation

Throws:

Exception

run

public void run()
         throws Exception

Description copied from class: Operation

Runs the operation. Either the Operation.run() or Operation.call() method should be implemented; not both. Runs after wait-support, supposed to do actual operation

Overrides:

run in class Operation

Throws:

Exception

Overrides:

writeInternal in class Operation

Throws:

IOException

readInternal

protected void readInternal(ObjectDataInput in)
                     throws IOException

Overrides:

readInternal in class Operation
