The subjective opinion was about "following" when Amazon has had relational database services for years, and the latest engine they say was under development for 3 years, not exactly something in response to goog.
Irrespective of that you shouldn't be posting as joe public when in fact you are a Google employee playing cheerleader for Google products on threads about your competitors products. Keep it classy.
We're not talking about a relational database, we're talking about a mysql-wire-compatible database. Google BigQuery has been around for a while too.
Adding "disclaimer: googler" to every post I make on HN seems pretty obnoxious to both me and anyone reading. I just didn't feel that "neat" + a fact qualified. Clearly opinions on that differ, and I'll probably just post less in the future.
