FoundationDB adheres to the highest level of consistency (linearizability) and, unlike Spanner or its derivatives, does not rely on clocks to achieve this.

I'm surprised FoundationDB is not mentioned in the article. Maybe it didn't help the author make his point, but it is both the most mature of the new breed of ACID+noSQL databases and completely free/open source.

One reason is may be because it is not 'SQL' DB, which is probably prerequisite for NewSQL category.

According to their docs, FoundationDB only provides serializable isolation, so it isn't the same as the others in the post which offer strict serializable isolation (multi-key version of linearizability). Without strong clocks you can't have strict serializablity and scale beyond a single log (but one log can get you pretty damn far). TBH most people probably only need serializable transactions anyway.

While that documentation isn’t wrong, FoundationDB also provides external consistency.
