NiFi block flowfile when failure

I set a Processor failure relationship to itself, when a flowfile process failed, I want it back to top of the incoming queue and retry again, also I send an email notification to administrator, after failure solved, the blocked flowfiles can be able to process aggin. Does NiFi support this ? enter image description here

You can drag multiple relationships from a processor, so you can have one failure connection that points back to itself and one failure connection that goes to a PutEmail processor which sends a notification to the administrator. If you want to prioritize the failed flowfile, you can use a funnel component to join the incoming queue with the failure queue and create a single joined queue with a prioritizer for "last in, first out".
