It may seem trivial, but claims like that are why I prefer CockroachDB when it comes to NewSQL systems. They’re at least very upfront with its compromises and areas needing improvement.
I’ve never see anything from Pingcap explaining the compromises that the DB makes. A “when should you not use this” type overview, and to me those are the most important things when deciding on a technology.
It may be good technology, but it’s marketed like modern day snake oil.
