> Hi,
> the {{KStreamPrintProcessor}} is implemented from scratch (from the {{AbstractProcessor}}) and the same for the related supplier.
> It looks to me that it's just a special {{KStreamPeekProcessor}} with forwardDownStream to false and that allows the possibility to specify Serdes instances used if key/values are bytes.
> At same time used by a {{print()}} method it provides a fast way to print data flowing through the pipeline (while using just {{peek()}} you need to write the code).
> I think that it could be useful to refactoring the {{KStreamPrintProcessor}} as derived from the {{KStreamPeekProcessor}} customizing its behavior.
> Thanks,
> Paolo.
