I’ve personally deployed O(TBs) and O(10^4 TPS) Postgres clusters on Kubernetes with a CNPG-style operator based deployment. There are some subtleties to it but it’s not exceeding complicated, and a good project like CNPG goes a long way to shaving off those sharp edges. As other commenters have suggested it’s good to really understand Kubernetes if you want to do it, though.

Thanks for the confirmation. As mentioned I'm not saying no to it. It is really that "really understand" part which holds me back for now - mainly the observability and dealing with edge cases in high-throughput environment.

What does this syntax mean? Surely you wouldn't use big-o notation with a constant in it, especially to convey the same meaning as the thing without the O?

Mathematically speaking the statement you are objecting to is correct: c1 is O(c2) for any constants c1, c2.

English-language-ly speaking the statement you are objecting to is also correct: both you and I managed to get it’s correct meaning.

No?

No, I am not sure about the meaning at all. Did they deploy databases that will tend to be a TB in size as something tends to infinity? Or multiple TBs? I don't know if they know about the constant factor since they don't know what the notation mean. Maybe they know what it means and are using it for a clever lie, a 1kB database is O(1TB). So is an empty database.

GGP is trying to be cool, and doing so stripped all meaning from their statement.
