Database read request are not the same as readonly HTTP requests. I am much happier having all requests hit my app process than I am trying to do the CDN dance.

Right now your choices are: run a database in on region and:

1. Use the weird HTTP header based cache API with a boring CDN

2. Write a second, JS based app with Workers or Deno Deploy that can do more sophisticated data caching

3. Just put your database close to users. You can use us for this, or you can use something like Cloud Flare Workers and their databases.

My hot take is: if something like Fly.io had existed in 1998, most developers wouldn't bother with a CDN.

Weirdly, most Heroku developers already don't bother with a CDN. It's an extra layer that's not always worth it.
