The dot product is computed between two vectors. For these use cases that dot product is equal to the cosine of the angle between these angles.
(Strictly speaking we have that the angle is actually defined in terms of the dot/inner product in more abstract spaces like function spaces or L^p/l^p)
Isolation can be quite important. I work with a micro services architecture, where we assign a database per service.
That makes it very easy to manage access to sensitive data.
But a smaller CRUD app wouldn't need "virtually unlimited scale". I'm very curious what their target audience is.
I find it to be super limited, and I'm sort of struggling to see the point given all these constraints.
No temporary tables, no foreign keys, no views, no more than 10k rows in a transaction.
Except for some basic wire compatibility with the postgres protocol, I'd hardly call this a "database", and more a key-value store.

No, the statement holds perfectly fine for the rationals.
I'm quite negatively surprised that a government service is moving from their own platform to AWS for such an important service.

I've seen people dump and share entire databases in JSON format at my job....
