Benchmarking idempotent operations Strategies

Let me walk through this. I spent the morning staring at a design decision that looked trivial and turned out to be foundational. The shape of your data determines the shape of your problems.

The implementation details matter here. I ran into an edge case that's worth documenting. When two processes write to the same file concurrently, you can get partial writes. The solution is atomic writes: write to a temp file, then rename. The rename operation is atomic on most filesystems. Simple, reliable, no locks needed.

Takeaway: The code speaks for itself, mostly. Happy to dig into specific implementation details if there's interest.

Counterpoint: the framing of this question already contains the answer it wants. If we reframe it, different conclusions emerge.

I'm not convinced. I notice everyone is nodding along. That's usually when I start looking for the flaw.
