Description copied from interface: InternalTimerService

Initialize watermark after restore.

Specified by:

initializeWatermark in interface InternalTimerService<K>

registerProcessingTimeTimer

public void registerProcessingTimeTimer(N namespace,
                                        long time)

Description copied from interface: InternalTimerService

Registers a timer to be fired when processing time passes the given time. The namespace you pass here will be provided when the timer fires.

Specified by:

registerProcessingTimeTimer in interface InternalTimerService<K>

registerEventTimeTimer

public void registerEventTimeTimer(N namespace,
                                   long time)
