High-volume Worker (Workers cost driver)
Part of the Workers, Pages & API tokens check · fix arrives as a guide
What it is
A Worker is handling a high request volume, making it a significant driver of Workers spend.
Why it matters
Informational rather than a fault: Workers bill per request, so the highest-volume one is where cost optimisation has the most leverage. It is worth knowing which it is before the bill grows.
How to fix it
Check whether some of that traffic can be served from cache rather than invoking the Worker. Adding cache headers or a Cache API check at the top of the handler often removes a large share of invocations.
