To my surprise, I could. It took ~a day and roughly $100 in API credits - and the result outperformed Vapi's equivalent setup by 2× on latency, achieving ~400ms end-to-end response times.

First, we iterate through the incoming state parameter rather than the local #data. That’s because if the incoming state is missing a key that #data has, we know that we don’t need to touch that key.8，这一点在体育直播中也有详细论述
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.
