https://github.com/apache/nifi/pull/3078
We should avoid calling this processor a 'PenalizeFlowFile' processor.
First, we have a notion of penalization in the framework already and it has a
very specific meaning and it kicks in when processors reach certain failure
conditions that are believed to be specific to a given flowfile or set of
flowfiles and that by penalizing them the condition might improve on its own.
Second, the use for this processor in a flow might not be for the purposes of
penalizing that flowfile but rather might simply be to cause a given wait or
hold to occur. I'd recommend calling it DelayFlowFile.
<...then I went and looked at the code>
It is literally just calling penalize flow file so it makes sense why the
name was given.
What use case is this for again?
If we're really wanting to create a DelayFlowFile processor, which is what
it sounds like was the intent, we should do that because penalization means
something else.

>
> Nifi has concept of penalization, but this penalization has fixed delay, and
> there isn't way how to change it dynamically.
> If we want to implement retry flow, where FlowFile flows in loop, we can
> either lower performance of Processor via yielding it, or we can do active
> waiting. And this is actually recommended as a correct way how to do that.
> It seems, that we can easily implement better RetryProcessor, all we missing
> is `session.penalize` which accepts `penalizationPeriod`. Processor then can
> gradually prolong waiting time after each failure.
>
> Would it be possible to make such method visible?
