- Data replication is common in distributed databases. Which site to query? Which site to update first and then the rest (with cascades)?
- If a site (or a link) fails then, on re-connecting the isolated sites, the relevant data commits done during the interruption must be updated.
- Transaction scheduling over multiple sites is much harder than the centralised case.
