It's very refreshing to see here that "attack" is not used in the way that one might expect from just the headline, meaning "a possibly unwarranted criticism that I didn't like or found unfair, or that I am taking personally".
My opinion of him and the Redis project increases further every time.
That said, I agree that DB reliability should be taken with the same rigor as net security...but I was kind of under the impression that it already was, in that DBs are pretty serious business. Also, "attack" has the connotation of, well, an "attack"...here, some of the failures happen in regular business operations, which is a problem different from when the system is under "attack".
But at least the OP took the criticism graciously. When I read what the case actually was, I then worried that the OP was having a bunker mentality.
