> The new Blink-based Table Runner needs "streaming pipelines" to be executed
> with {{ScheduleMode.LAZY_FROM_SOURCES}} if all sources are bounded. The
> current Blink code base uses a global flag for this and configures the
> {{StreamGraphGenerator}} accordingly.
> We propose to add an {{isBounded()}} property to {{Transformation}} (formerly
> known as {{StreamTransformation}}). The property would only be explicitly
> settable on sources, other transformations inherit the property from their
> inputs. The {{StreamGraphGenerator}} must use
> {{ScheduleMode.LAZY_FROM_SOURCES}} if all sources are bounded, otherwise, it
> should use {{ScheduleMode.EAGER}}, as is the currently existing behaviour.
