> Right now, the {{AssignerWithPunctuatedWatermarks}} and 
> {{AssignerWithPeriodicWatermarks}} interfaces also require implementing a

> For cases where the source emits records with timestamps, its not necessary 
> to extract timestamps again from the records, we just want to generate 
> watermarks.
