Hello [~mkapkiai],
>From the NiFi framework point of view 'success' is just the name of the
>relationship. The framework itself has no information about the intended use
>of a relationship. So the retry framework handles every relationship equally
>this is why retry can be set on a 'success' relationship.

> For a processor that routes to failure, in NiFi I have 3 options:
> 1) Loop 'failure' back to the processor and retry forever
> 2) Auto-terminate or route the data elsewhere without any retries
> 3) Build a complex retry loop that creates or updates an attribute, routes on
> that attribute to determine whether or not we've exceeded the maximum number
> of retries, and if not penalizes the FlowFile (typically with a Script
> processor) and then routes back to try the FlowFile again.
> This provides a poor user experience and poor performance and results in very
> complex flows that are difficult to understand and maintain.
> As a user, when I configure a Processor, I should be able to indicate that
> for Relationship ABC, I want to retry the FlowFile 5 times. Then, if the
> Processor transfers a FlowFile to that relationship, it should instead
> transfer the FlowFile back to its original queue and increment the transfer
> count for that relationship from 0 to 1 and penalize the FlowFile. If the
> Processor processes it again and transfers it to the same Relationship again,
> it'll again put it back to the original queue and increment the count to 2.
> Only when the data is routed to that Relationship 5 times (because that's the
> configured retry count in this example) should the FlowFile actually be
> transferred to that corresponding connection(s) or auto-terminated, as the
> flow is configured.
