thing is, if you google for it, you will find it as a technique https://docs.oracle.com/database/121/VLDBG/GUID-5A76B6CE-C96... which I can imagine is used to justify the path they were on.

and we must note that the business side did eventually bring in external consultants because the project was clearly distressed. So it did eventually get corrected and I naturally tend to see the worse examples of this kind of thing, but yeah, it is possible to assemble a team of 8 developers and get unlucky such that not a single one knows anything about indexes or cloud databases in general.

I think it’s ridiculous since I come from an era where it was considered basic knowledge. I can’t imagine a software engineer that doesn’t have a passing familiarity with the goals of indexes (even if they don’t know exactly how they work).

But that’s turning out to be more and more untrue. Newer engineers really do not know.
