How does LMDB write to the database with a read-only mmap?
I am starting to learn about LMDB, but I am having trouble understanding how LMDB writes to a read-only mmap (read-only is the default configuration). Does anyone have a simple explanation as to how this works?

It uses the filesystem API to write, preferentially pwritev on Unix.
