> Streaming programs currently use the same lazy operator execution model as batch programs.
This makes the functionality of some operators like time based windowing very awkward, since
they start computing windows based on the start of the operator.
> Also, one should expect for streaming programs to run continuously so there is not much
to gain from lazy execution.
