To summarize, the kernel first translates the destination userspace virtual address to its backing physical frame via a software page table walk. Then it maps this frame into its own virtual address space as RW. Finally, it performs the writes using a simple memcpy.
This is another area where Rails 8 gave me a very pleasant surprise. I really like PostgreSQL as a database (and much more besides) - I used to maintain the Solaris packages for Blastwave/OpenCSW waaaay back (now that really does age me!) and have run it in production for decades now. But it’s still another dependency to manage, back-up and scale. SQLite by comparison is as simple as it comes: Single file, no DB server required.
