Aldrin Piri commented on NIFI-810:
----------------------------------
Bah, sorry for never having responded. You were consumed by the blackhole that
is my inbox.
The InputRequirement looks good and probably makes it easier than having to do
additional checking on annotations applied to make sure everything makes sense
(IgnoresInput and RequiresInput applied to a processor). From the standpoint
of clarity, this seems like the best path in my view.
> Create Annotation that indicates that a Processor cannot be scheduled to run
> without an incoming connection

> Currently, if a Processor has no incoming connections but is started, it will
> continually without ever accomplishing anything. We should have an
> annotation, perhaps @RequiresInput, that indicates that the Processor should
> not be scheduled to run unless it has an incoming connection.
