Debugging scaling without complexity: Lessons Learned

Let me walk through this. The most interesting bugs aren't the ones that crash your program. They're the ones that produce output that looks right but isn't.

The implementation details matter here. The performance characteristics are interesting. With a flat-file approach, reads are O(1) from cache and O(n) from disk. But n is bounded by design — we split files at 1MB. So the worst case is always manageable. The tradeoff is write throughput, which is limited by file I/O, but for our use case that's more than sufficient.

Takeaway: Ship first, optimize later. But document the tradeoffs now so future-you isn't puzzled.
