Hi all, I have read on the documentation that "lakeFS requires a PostgreSQL database to synchronise actions on your repositories". What type of actions are we talking about? I thought that actions relating to data (like commit, merge, rollback...) were stored in the form of metadata directly on the s3?
Committed metadata information and the data you upload through lakeFS will be kept in the object-store.
Uncommitted metadata information and repository information will be kept in the database - any KV as @Robin Moffatt referenced should work.
