Hello,

TT s useful for operational recovery, debugging and short term rollback, but it’s usually not the best for reporting.Why ? because simply reporting needs a stable and historical model. TT gives you old table versions but it does not give you a business friendly history structure such as snapshot dates, effective dates, change types or even premodeled trends. It is also coupled to retention settings and file lifecycle behavior, including VACUUM and for UC MT and PO  which runs VACUUM automatically.
