Sure, but this particular case clearly wasn't using cache, that's why the free tier limit for an application was reached. Hence it's highly likely that each request hit a database.

The message would've been different if it was cached.

Cloudflare Workers run in front of cache -- which is generally useful since it allows you to serve personalized pages while still pulling the content from cache, and since Workers can easily run in <1ms and run on a machine you were already going to pass through anyway (the CDN), it doesn't hurt performance. But it also means that the free tier limit of 100,000 requests per day includes requests that hit cache.

(I'm the tech lead for Workers.)
