That is actually insane. The day their MySQL cluster experiences a severe downtime incident, it is likely going to take an enormous amount of time to recover.

That is actually insane. The day their MySQL cluster experiences a severe downtime incident, it is likely going to take an enormous amount of time to recover. That is my intuition. If you know of a video or blog post (conference, talk, article, etc.) where someone explains the benefits of a 2 TB MySQL server and how it is not a crazy bad idea, I would love to see it. Because my 15 years of professional experience screams "NO WAY IN HELL" at that one.
