I think he did mention this indirectly. Mongo performs better than Rethink on metrics that have nothing to do with what you truly want from a DB. He mentioned developers that would just whip up a script to throw thousands of writes at the database but never reads. Use cases that they would never see in real scenarios. First, you would need to educate your market that they need to care about the CAP theorem and what that is, that Rethink was damn good CP and that while Mongo might be fast, it isn't correct.

Why not call them out then? It should take only one or two blog articles to explain why mongodb benchmarks are bogus. I fail to believe it is hard to teach some database knowledge (CAP and others) to your potential customer when they are developers. Heck, it would even boost your SEO by a ton.

"All you had to do was aggressively market yourself as the better option by directly comparing yourself to it."

Lol. "It's not hard to win an Olympic medal in the 100m sprint. All you have to do is move your legs faster than those other guys!"

But they were and still are better than mongodb? They already achieved that ?
