org.apache.flink.streaming.connectors.kafka.internals.KafkaTopicPartitionStateWithWatermarkGenerator<T,KPH>

类型参数:

T - The type of records handled by the watermark generator

KPH - The type of the Kafka partition descriptor, which varies across Kafka versions.

@Internal
public final class KafkaTopicPartitionStateWithWatermarkGenerator<T,KPH>
extends KafkaTopicPartitionState<T,KPH>

A special version of the per-kafka-partition-state that additionally holds a TimestampAssigner, WatermarkGenerator, an immediate WatermarkOutput, and a deferred WatermarkOutput for this partition.

See WatermarkOutputMultiplexer for an explanation of immediate and deferred WatermarkOutputs..
