How to inspect data cache?

[MangoMarcus]

I'm finding Next's caching mechanisms very opaque, which makes them hard to debug and troubleshoot.

I've recently had an issue where using revalidateTag doesn't seem to refresh a pre-rendered page on Vercel, I'm guessing there's another layer of caching which should be invalidated but isn't. I haven't been able to resolve it without just clearing the whole data cache on Vercel.

It would be very useful to have some visibility / transparency on what exactly's being cached and when.

There's some means to do this locally by trawling the .next directory, but there doesn't seem to be any way on Vercel unless I'm missing something??

I agree, this would be useful for debugging purposes to know what's being stored in there.

Bump on this? Any known way to inspect build-cache size on Vercel deployments?

also need this feature to get some bugs fixed.

This would be very useful

Up, really need to debug why build cache size is so big

Upping, would be a really nice addition to the Observability in Vercel.
