>
> Punctuate() function in processor and transformer needs to be handled a bit
> differently from process(), since it can generate new records to pass through
> the topology from anywhere of the topology, whereas for the latter case a
> record is always polled from Kafka and passed via the source processors.
> Today because we do not set the curRecord correctly, calls to timestamp() /
> topic() / etc would actually trigger a KafkaStreamsException.
