[jira] [Created] (NIFI-8602) Managing older NARs within NAR autoloader

Simon Bence created NIFI-8602:
---------------------------------

             Summary: Managing older NARs within NAR autoloader
                 Key: NIFI-8602
                 URL: https://issues.apache.org/jira/browse/NIFI-8602
             Project: Apache NiFi
          Issue Type: Improvement
          Components: Extensions
            Reporter: Simon Bence
            Assignee: Simon Bence


Based on [~markap14]'s improvement idea on the original ticket:

It's possible that over time users will continually add new versions of a NAR to the same directory. And over time this will result in loading massive amounts of NAR's into NiFi. Those that get removed will remain in NiFi. We will need some way to age off old NARs. Perhaps after performing a listing, we should detect any nar's that were previously downloaded from that NarProvider and not present in the Listing. Then, if any of those is not in use (i.e., no extensions are in the flow that use that bundle) then we can remove the bundle and its NarLoader.
