public ReplicationExecutor(Peer peer,
                   ReplicationFactor replicationFactor,
                   ReplicationSender replicationSender,
                   Random random,
                   ScheduledExecutorService timer,
                   int delayMillis,
                   boolean allPeersReplicate)

Constructor for the default indirect replication.

Parameters:

peer - The peer

Method Detail

init

public void init(int intervalMillis)

otherResponsible

public void otherResponsible(Number160 locationKey,
                    PeerAddress other,
                    boolean delayed)

Description copied from interface: ResponsibilityListener

Here an other peer is responsible and we need to transfer data.

Specified by:

otherResponsible in interface ResponsibilityListener

Parameters:

locationKey - The location key

other - The other peer that is responsible for locationKey

delayed - Indicates if the other peer should get notified immediately or delayed. The case for delayed is that multiple non responsible peers may call this and a delayed call in that case may be better.

meResponsible

public void meResponsible(Number160 locationKey)

Description copied from interface: ResponsibilityListener

The responsibilty changed to our peer. That means we are now responsible.

Specified by:

meResponsible in interface ResponsibilityListener

Parameters:

locationKey - The location key

meResponsible

public void meResponsible(Number160 locationKey,
                 PeerAddress newPeer)

Specified by:

meResponsible in interface ResponsibilityListener

run

public void run()

Specified by:

run in interface Runnable

send

protected List<PeerAddress> send(Number160 locationKey,
                     Map<Number640,Data> dataMapConverted)

If my peer is responsible, I'll issue a put if absent to make sure all replicas are stored.

Parameters:

locationKey - The location key

domainKey - The domain key

dataMapConverted - The data to store

Returns:

The future of the put

shutdown

public void shutdown()
