Bryan Rosander commented on NIFIREG-238:
----------------------------------------
Pr at [https://github.com/apache/nifi-registry/pull/162] allows arbitrary
number of aliases in xml config file. You should be able to sync that across
multiple registries if desired.
> Support Registry URL Aliasing
> -----------------------------
>
> Key: NIFIREG-238
> URL: https://issues.apache.org/jira/browse/NIFIREG-238
> Project: NiFi Registry
> Issue Type: New Feature
> Reporter: Bryan Rosander
> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h
>
> It would be nice to be able to change the URL of a NiFi Registry without
> rewriting all flow history.
> In a deeply nested flow where there are dependencies on potentially multiple
> versions of the same process group, this doesn't seem to be possible. (You
> can update the URL in the latest version but cannot retroactively change it
> for the benefit of process groups pointing at the older version(s).)
> If we allowed for aliasing of that field, this would be a non-issue, it could
> be stored as a token (or original url) inside the registry and rewritten when
> requested. When persisting, it could be translated back to the token value.
