> In the current form, an operator can replace it's position with its own instances. We call this partitioning. There are use cases when the operators can replace themselves with dags which will be semi permanent as in each of the operators in this replaced dag play the primary operator role as the original operator until needed.
> One such use case is structured query execution. 
> We can start with the static dag creation (functionality that StreamingApplication already has) and peel our way to dynamic behavior.
