I was under impression that only Spanner-like databases (CockroachDB and FaunaDB) are the only ones that can do cross-datacenter multi-row transactions at scale. Because they were designed exactly for this, otherwise tradeoffs taken are just too bad for the that use-case (e.g. too slow or too brittle in availability). By cross-datacenter I mean datacenters far away from each other, in different geo regions.
