> Right now there is no reliable way of passing WatermarkGeneratorSupplier
> and/or TimestampAssigner as lambdas in scala.
> The only way to use this API is:
> {code}
> .assignTimestampsAndWatermarks(
> WatermarkStrategy.forGenerator[(String, Long)](
> new WatermarkGeneratorSupplier[(String, Long)] {
> override def createWatermarkGenerator(context:
> WatermarkGeneratorSupplier.Context): WatermarkGenerator[(String, Long)] =
> new MyPeriodicGenerator
> }
> )
> .withTimestampAssigner(new SerializableTimestampAssigner[(String,
> Long)] {
> override def extractTimestamp(t: (String, Long), l: Long): Long =
> t._2
> })
> )
> {code}
