Many open-source project use redis just as a cache. What about harbor? why it use it?
I want to be sure if redis data must be:
- persitent on redis statefulset upgrade - is that data important and must be backup? but as PostgreSQL is already there... I assume critical data that need integrity is stored there. I assume it might just be user sessions. - is redis can be rebuild from PostgreSQL, just not efficient when redis start from a blank PVC.
