And that's why we have the "NewSQL" movement, though a bit slow. The benefit of NoSQL in some cases (Cassandra and HBase for me) is that it restricts developers from using non-scalable data structuring and querying. RDBMS's have a bad reputation primarily because how they were used via unrestricted queries that came back to haunt the product owners. And even then, some local DB approaches are fundamentally unsolvable in a distributed way (CAP, exactly-once-sends, etc) without trading something, even with cockroach.
