We don't cache query responses in the Starbase application layer. When we originally set out to build this, we were under the assumption we had to handle the ACID transactional support ourselves. Thankfully someone from Cloudflare shed some light for us as you can see in our Github issues and open PR's :)
Just fyi, the person that replied wasn't just "someone" at Cloudflare. It was Kenton Varda (kentonv here). He's the creator of Cloudflare workers, he's an incredible engineer.
