Method Details

notify

public void notify(Notification notification)

This method permits to just send a notification. For the channels that implements For ConnectChannel an empty Partition and Offset will be sent with the SourceRecord

Parameters:

notification - the notification to send

notify

public void notify(Notification notification,
 Offsets<P,? extends OffsetContext> offsets)

This method permits to send a notification together with offsets. This make sense only for channels that implements For ConnectChannel A notification is sent also to non ConnectChannel

Parameters:

notification - the notification to send

offsets - the offset to send together with Kafka SourceRecord

incrementalSnapshotNotificationService

public IncrementalSnapshotNotificationService<P,O> incrementalSnapshotNotificationService()

isEnabled

private Predicate<? super NotificationChannel> isEnabled()

isConnectChannel

private Predicate<? super NotificationChannel> isConnectChannel()

stop

public void stop()
