I've had good success with just using mypyc (https://mypyc.readthedocs.io/en/latest/introduction.html) on typed python code.

Lamport lists his collected works on his site[0] along with some commentary for each one, and directly mentions, The Maintenance of Duplicate Databases, as the origin for logical clock paper. Many of the notes have interesting commentary.

> Many computer scientists claim to have read it. But I have rarely encountered anyone who was aware that the paper said anything about state machines. People seem to think that it is about either the causality relation on events in a distributed system, or the distributed mutual exclusion problem. People have insisted that there is nothing about state machines in the paper. I've even had to go back and reread it to convince myself that I really did remember what I had written.[1]

Did you read the article?

Sibling comment touched on it, and I guess rust does offer just that, but void casting and doing explicit offset checks for a field is one reason. You can kind of think of it like a tuple in that way and a db engine might use a similar technique.

I think the size of linked binaries and simplicity were always the main features?

This reminds me how you can save a bunch of bytes just by making sure your structs are aligned. In go for example:

  type Wasteful struct {
    a int16
    b int
    c byte
  }

  type Aligned struct {
    b int
    a int16
    c byte
  }

Will have sizes of 24bytes and 16bytes (on a 64bit system). Same data 8bytes more. If you are storing millions of those objects, then it adds up.

Except that eventually you'll find you lose a write when things go down because the page cache is write behind. So you start issuing fsync calls. Then one day you'll find yourself with a WAL and buffer pool wondering why you didn't just start with sqlite instead.
