> As discussed in FLINK-7446, currently the TableSource only support to define 
> rowtime field, but not support to extract watermarks from the rowtime field. 
> We can provide a new interface called {{DefinedWatermark}}, which has two 
> methods {{getRowtimeAttribute}} (can only be an existing field) and 
> {{getWatermarkGenerator}}. The {{DefinedRowtimeAttribute}} will be marked 
> deprecated.
> How to support periodic and punctuated watermarks and support some built-in 
> strategies needs further discussion.
