yes ! this is what I asked for a couple of weeks ago, on a suggestion by
Farid of CPW (Vinay's collegue), versioning the records for long running
transactions and optimistic locking with distributions that have low rw
MAKES TOTAL SENSE.
However we can do it at the container level, not even at the db level
