From e02095c5b6e04f70ae6562f5aee169f7ee93cf7a Mon Sep 17 00:00:00 2001 From: Earl Warren <109468362+earl-warren@users.noreply.github.com> Date: Mon, 18 Dec 2023 16:32:08 +0100 Subject: [PATCH] Add orphaned topic consistency check (#28507) - If a topic has zero repository count, it means that none of the repositories are using that topic, that would make them 'useless' to keep. One caveat is that if that topic is going to be used in the future, it will be added again to the database, but simply with a new ID.
