> In Stream DSL, all broadcasting slave operations tailing a master operation will be translated to individual tasks. 
> For example, 
> {code}
> val stream = StreamApp.source(source, 1, "source")
> stream.filter(fn, "filter A")
> stream.filter(fn, "filter B")
> stream.filter(fn, "filter C")
> {code}
> This will be translated to 1 SourceTask and 3 FilterTasks although it's possible for them to be done in 1 Task.
