Hi all,
Can we access individual elements from a DataStream through an iterator like we 
can in a WindowedStream with the apply function?
I am able to access the elements of a WindowedStream using the apply function 
and using the Iterable and Collector interfaces:
val ds = ws.apply((K, W, input: Iterable[T], output: Collector[R]) => {
   val it = input.toIterator
   while(it.hasNext){      ...   }})

the output of this function is a DataStream. I want to perform a keyBy on this 
DataStream and then again iterate through it's individual elements. We cannot 
use the apply function on DataStreams like in WindowedStreams. Is there any 
other way? Thanks and Regards,Piyush Shrivastava
