> Unmatch records to filter functions should send somehow to side output.
> Example:
>  
> {code:java}
> datastream
> .filter(i->i%2==0)
> .sideOutput(oddNumbersSideOutput);
> {code}
>  
>  
> That's way we can filter multiple times and send the filtered records to our side output instead of dropping it immediatly, it can be useful in many ways.
>  
> What do you think?
