Mark Payne commented on NIFI-4805:
----------------------------------
[~alfonz] the delay that is imposed by the session penalization is controlled
in the Processor's Settings configuration dialog. We did used to have a
session.penalize method that allowed the developer to indicate a penalization
period. As a result, developers typically would expose this configuration via a
processor property. Or sometimes multiple properties - "Penalization Period for
ABC", "Penalization Period for XYZ", "Penalization Period for This Other
Thing". This ended up becoming confusing for users, because it was just more
complicated to configure this, and every processor configured this differently.
As a result, it was eventually removed all together and placed just on the
Settings pane for the processor.

> Components: Core Framework

> 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?
