It would be interesting to know how much data Google stores in traditional RDBMS versus NoSQL stores (BigTable, Spanner[0], etc.). I could probably track down this number, but then I expect I wouldn&#x27;t be able to talk about it after, so for now I&#x27;m saying ignorance is bliss :). I would wager that we&#x27;re rather more NoSQL heavy than most organizations, so it wouldn&#x27;t really be a good proxy for the industry in general, but it might be helpful for justifying Steve&#x27;s claim. It might be particularly helpful if we looked at the workloads Google runs on NoSQL stores that traditionally would have mandated an RDBMS.<p>[0]: <a href="http:&#x2F;&#x2F;research.google.com&#x2F;archive&#x2F;spanner.html" rel="nofollow">http:&#x2F;&#x2F;research.google.com&#x2F;archive&#x2F;spanner.html</a>
