"No stale reads" is the simplest way to describe this consistency model which has deliberately made the trade-off of having non-linearizable transaction histories. Transactions containing overlapping keys are guaranteed to have external consistency. And so, in practice, systems relying on CockroachDB are very unlikely to reproduce consistency issues because nodes with high variations in clock skew can be removed from clusters, applications can rely on external consistency provided by overlapping keys and writing to the same range, and writes propagate changes to followers' timestamp caches.
