> Inside the iteration, we will also broadcast the special events to mark the end of rounds. To process these events, all the operators inside the iteration is wrapped with a specialized wrapper operator. 
> There are two kinds of wrappers: the first wrapper would not recreate the users' operator for each round, and the second one would. This issue would implement the first kind.
