it's as much engineering as is gluing mmap, recv and send... there are people who can do that and can't piece together a dataframe pipeline, no need to be passive agressive here

As you can see from comments up this thread (ref. various GitHub issues) - the people "gluing mmap" don't actually have a single clue. They can't properly measure memory consumption (they don't understand what the numbers they're seeing actually mean). They don't understand how paging, swapping or virtual memory work. They don't actually understand the concept of memory-mapped files, why they're there and how they work. They can't explain why their code behaves differently when using memory-mapped files.
Moments like this are here to remind you that there's actual knowledge and skill to building scalable and efficient software, and that hustling and copy-pasting StackOverflow examples will only get you so-far, as will "piecing together dataframe pipelines" in Python.
