> Teams spending weeks exchanging SQL DB for No SQL DB because of unsolvable performance problem. When hitting the same problem with NoSQL DB, they find that addition of a simple index is solution in both cases

I don't get the idea that one has to pick either SQL or NoSQL, but a lot of people seem to think this way. Why not use both? The SQL portion can more or less be treated as a rich index of relationships, and the NoSQL portion can handle performance when it makes more sense for data to be embedded in parent documents.

Indeed, there is no reason to pick a "side". All big systems I have seen either have both or would benefit from both.

In fact, our current system has PG and several NoSQL databases, because each product has its own strengths.
