Hi, As far I know ListS3 use NiFi built in StateManager which in turn use StateProvider's. NiFi may have different StateProvider implementations. Currently NiFi have 2 providers, ZooKeeper based and write-ahead log file based. ZooKeeper is used when NiFi cluster is configured and other is used for local single node NiFi. As I understand NiFi will choose automatically ZooKeeper for cluster and local for single NiFi instance.
You can Replay FlowFile. Open Data Provenance, choose Provenance Event, open CONTENT tab and click REPLAY. Also many NiFi processors have Failure relationship which is used to route failed FlowFile’s to some other path. So you can automate how to handle failed FlowFiles. Data Provenance is simplest way to see successfully processed files. But you can create custom Reporting Task to collect Provenance Events and do what ever you need.
