What's the difference between a request and a subrequest?

I'm checking my analytics, workers invocations adaptive, and I see a requests_sum and subrequests_sum, totaling 265 and 175 respectively. What do these two metrics mean?

What does "other resources" entail? Would a fetch request to download a file count as a subrequest? Would a GraphQL query to analytics count as a subrequest? Or does it exclusively mean Cloudflare's cloud resources like D1 or R2?

Theyre internal subrequests, some analytics/limits count them and others dont

Is it documented anywhere which do and don't count them? It's been hard to find documentation on the GraphQL analytics.
