public interface IracManager

It manages the keys changed in the local cluster and sends to all asynchronous backup configured.

lockOwner - The lock owner who updated the key.

trackUpdatedKeys

<K> void trackUpdatedKeys(Collection<K> keys,
                          Object lockOwner)

Sets all the keys in keys as changed by the lockOwner.

Parameters:

keys - A Collection of keys changed.

lockOwner - The lock owner who updated the keys.

trackKeysFromTransaction

void trackKeysFromTransaction(Stream<WriteCommand> modifications,
                              GlobalTransaction lockOwner)

Sets all keys affected by the transaction as changed.

Parameters:

modifications - The Stream of modifications made by the transaction.

lockOwner - The GlobalTransaction.

trackClear

void trackClear()

Sets all keys as removed.

cleanupKey

void cleanupKey(Object key,
                Object lockOwner,
                IracMetadata tombstone)

Sets the key as not changed and remove any tombstone related to it.

If lockOwner isn't the last one who updated the key, this method is a no-op.

Parameters:

key - The key.

lockOwner - The lock owner who updated the key.

tombstone - The tombstone (can be null).

onTopologyUpdate

void onTopologyUpdate(CacheTopology oldCacheTopology,
                      CacheTopology newCacheTopology)

Notifies a topology changed.

Parameters:

oldCacheTopology - The old CacheTopology.

newCacheTopology - The new CacheTopology.

requestState

void requestState(Address origin,
                  org.infinispan.commons.util.IntSet segments)

Requests the state stored in this instance for the given segments.

Parameters:

origin - The requestor.

segments - The segments requested.

receiveState

void receiveState(Object key,
                  Object lockOwner,
                  IracMetadata tombstone)

Receives the state related to the key.

Parameters:

key - The key modified.

lockOwner - The last lockOwner.

tombstone - The tombstone (can be null)
