Method Detail

startLogRecoveryBatch

void startLogRecoveryBatch(int maxBatchSize)

This method is called during recovery at the start of a batch of state entries. Derived classes should perform any initialization needed to start a batch.

Parameters:

maxBatchSize - the maximum batch size.

appendRecoveredLogEntry

void appendRecoveredLogEntry(Payload data)

This method is called during recovery to append state data to the current batch. This method is called 1 or more times after startLogRecoveryBatch(int).

Parameters:

data - the state data

applyRecoverySnapshot

void applyRecoverySnapshot(Snapshot.State snapshotState)

This method is called during recovery to reconstruct the state of the actor.

Parameters:

snapshotState - A snapshot of the state of the actor

applyCurrentLogRecoveryBatch

void applyCurrentLogRecoveryBatch()

This method is called during recovery at the end of a batch to apply the current batched log entries. This method is called after appendRecoveredLogEntry(org.opendaylight.controller.cluster.raft.protobuff.client.messages.Payload).

getRestoreFromSnapshot

@Nullable Snapshot getRestoreFromSnapshot()

Returns the snapshot to restore from on recovery.

Returns:
