You're aware that the vendor will post gospel about their product on their own website? I'm not using Postgres, I use MySQL, but I can assert with 100% certainty that most of the "comparison" on that URL is just marketing bullshit. You're a prime example that this new-age bullshit works and that's what's worrying.
How's that relevant? You're neither lead architect nor does your employment at MySQL / Oracle mean anything. Many incapable developers score positions at big companies. Without facts, maths and measurement you can be Linus Torvalds for all I care. The article at the URL provided is simply marketing ploy. I'm experienced enough to notice what's wrong with the comparison, but I won't take that article apart to prove anything. If you believe Mongo is a product that helps you - perfect. Now, if you're thinking you'll convince me that it's great by berating another great product - well, that raises a red flag. Who says I've to use a single software vendor anyway?
it was the reference to me as "You're a prime example that this new-age bullshit works and that's what's worrying". The same statements were leveled at anyone from mysql 10-15 years ago. I'm glad mysql works well for your use-case
Are you the Mat Keep who is Director of Product Marketing at MongoDB? If so then, FWIW, people don't often respond well to marketing links posted without identifying your connection to the company.
