---------------------------------------

             Summary: Consolidate TimestampAssigner Methods in Kafka Consumer
                 Key: FLINK-3747
                 URL: https://issues.apache.org/jira/browse/FLINK-3747
             Project: Flink
          Issue Type: Improvement
          Components: Streaming
            Reporter: Aljoscha Krettek
            Priority: Blocker


On {{DataStream}} the methods for setting a TimestampAssigner/WatermarkEmitter are called {{assignTimestampsAndWatermarks()}} while on {{FlinkKafkaConsumer*}} they are called {{setPunctuatedWatermarkEmitter()}} and {{setPeriodicWatermarkEmitter()}}.

I think these names should be matched, also the name {{setWatermarkEmitter}} does not hint at the fact that the assigner primarily assigns timestamps.
