Andy LoPresto commented on NIFI-4805:
-------------------------------------
I almost opened what I think is a duplicate of this today; I was going to
propose a {{Sleep}} processor which takes a configurable property as the delay
time and just waits to release the flowfile. I think it should support
Expression Language and in the context of the penalization, maybe a counter of
the number of times this flowfile has been penalized so that exponential
backoff like Martin described above could work.

> URL: https://issues.apache.org/jira/browse/NIFI-4805
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Reporter: Martin Mucha
> Priority: Minor
> Attachments: retry.xml

>
> 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?
