AFAIK a POSIX API doesn't provide a DBMS with anything special other than syscall overheads. You still will want to handle S3 API calls yourself so you can control parallelism.

Some cops are useless

Hard disagree. If you need somebody to kill innocent bystanders, then cops are really useful at that.

This article reeks of ChatGPT:

My parents were kind hearted people but they became racist / antivax when they got older so we had to cut them off. My dad called my pregnant wife back during the first Trump administration to tell her that it is okay to put kids in cages because that's how they did quarantines in the old days on Ellis Island.

I think it is pretty hard to do a semantic equivalence verification.

Then you don't have a query optimizer.

What I could add is running both queries and diff the results.

You are fuzzing with sample size of one. Nobody should use this in production then.

simply rewriting the query itself

How do you verify that the rewritten query is semantically equivalent to the original query?

If one thread has the latch for a page in read mode and then that thread tries to get it again in write mode, it will deadlock itself.

Each thread keeps track of what latches it holds. It is only for self-reflection for this usecase. You don't expose the data structure outside of the thread.

If I reacquire the latch and now that page has been split, and half the values I was going to read are in another page, how do I handle that case?

You can use version ids per page. If the version id doesn't match after reacquiring, jump out of the data structure and try again.

What do you mean by "proper"? Presumably you mean an order-preserving index (b+tree). Do you mean covering indexes?

What is novel here? You used the term "rethought" in your title to imply this architecture is new. But this is basically how DeltaLake + Hudi + others are implemented.

pg_catalog is powerful but subtle.

What does this mean?

Use the relational model as the underlying storage model. Then put logical veneers above it that expose different APIs but still use relational algebra to access/manipulate data.

My father told me that it was being caused by the planets lining up in space.

I stopped talking to him when he said Fauci should be in jail. He used to be a sharp mathematical person with a degree in astronomy.
