i don’t think it’s that complicated. your account is in a US database. your friends in a french database. the us db can have a list of friends by user id and those friends might be in other countries db. however your identity and data live in us db only. if you create a message the message can either be stored in the us and referenced by id in france (or duplicated since you intentionally sent it there). same for photos this makes each transmission of data across regional boundaries more intentional and easy to add governance checks
