From the intro page[1]... Many of the descriptions comparing to NoSQL are wrong. There are plenty of NoSQL options that have similar features, though it isn't universal, it can and often is there. Cassandra, for example, probably does just as well in multi-zone/dc concurrency. Consistency options are also similarly tunable. Cockroach 1.0 was announced earlier as well.
It's not that I don't appreciate the option. This seems far closer to what DocumentDB should have been earlier on. Though tbh, I think Storage Tables are already pretty useful.
