Competence is not writing 576,000 lines. A database persists (and processes) data. That is all it does. And it must do it reliably at scale. The difference between O(log n) and O(n) on the most common access pattern is not an optimization detail, it is the performance invariant that helps the system work at 10,000, 100,000 or even 1,000,000 or more rows instead of collapsing. Knowing that this invariant lives in one line of code, and knowing which line, is what competence means. It is knowing that fdatasync exists and that the safe default is not always the right default.
