Memory mapping is a poor way to make a database[0], not all storage can be memory mapped, and this doesn't provide any of the functionality you expect of a database like indexing and concurrency control.

I saw a headline about the book on Reddit and made a joke to a friend of mine: "How much you wanna bet it uses mmap?" Well...

It uses mmap.


The concurrency control is managed by the server that manages access.

All databases that are any different than these two points are just bad.
