             Summary: Figure out how to clean up state storage, if at all
                 Key: MINIFICPP-1174
                 URL: https://issues.apache.org/jira/browse/MINIFICPP-1174
             Project: Apache NiFi MiNiFi C++
          Issue Type: Task
            Reporter: Dániel Bakai


I am not sure when we want to clean up state storage at all. For example, if a new configuration is loaded, we might want to clean the state of components that no longer exist in the flow, but this would mean that a single misconfiguration would make us loose our state (and that we can't properly roll back to an older configuration, because we have lost the state of processors no longer referenced). For the time being I think it is perfectly fine not to do any state cleanup: we don't have many processors using state, we don't have many instances of those processors that do use state, and states are small strings. We can handle the at maximum few hundred states stored in our DB (and this is the most extreme example I can imagine). If it really becomes an issue for someone, they can just delete the state directory/file.
