David Handermann commented on NIFI-12783:
-----------------------------------------
I concur with your recommendation [~pvillard]. Introducing a new required
relationship would have a significant impact on existing flows, and may not be
applicable in all cases. Introducing a new Failure Strategy property, which
would enable a relationship, seems like the better way forward.

> Hi,
> the Kafka producer processors do not route the FlowFiles on a timeout e.g.
> into the failure connection. They are yielded in the incomming connection.
> You can see the behaviour here e.g.:
> [https://stackoverflow.com/questions/71460008/apache-nifi-publishkafka-timeout-exception]
> I think this is a design flaw. I have a use case where messages should be
> dropped after a specific configurable time. If the messages are yielded in
> the incomming queue they are always published when the kafka broker are
> available again. I know I can set the expiration time in secs or mins in the
> incomming queue but it is not dynamically configurable because no attributes
> are allowed.
> Best
