You'll be charged for CPU time and amount of requests, not waiting for IO, since this is IO and you're not doing/awaiting for any CPU actions it shouldn't be too much. This will incur probably at most <10ms (probably less) of CPU time per request. I don't think you pay for the data transferred at all, but not 100% sure about that in terms of ingress.

The entire function is wrapped in a try catch so any error would be logged and thrown.

tonytheonly•4/30/24, 12:59 PM

That being said I get now errors, and when looking at the logs of the localhost:3000 i see no console log of the request. However when I post the same information in postman to localhost:3000 I get a console log

Does someone know something about function usage on static page rendering in next on pages, as disccused above:

https://community.cloudflare.com/t/loading-static-page-counts-towards-function-request/535651

Is this really like this? Is this situation shared among all other frameworks/ssgenerators? I mean, do they all incur in function usage when rendering static pages? I was reading about Astro, and it seems nice but I dont know if may be it´s the same with all frameworks.

Does anybody know if the Cache API supports Cache Reserve?

Rich•4/30/24, 3:54 PM

do you know if Cache Reserve / R2 is global or per colo?

Chaika•4/30/24, 3:58 PM

it's an r2 bucket, r2 buckets are offered in a few locations but it's just like s3 in the sense that it's persistent object storage

Chaika•4/30/24, 3:59 PM

you have three options for cache
Local Colo Cache <- only one Cache API will ever touch
Tiered Cache <- can vary depending on setup, either Smart (one) or Generic (a few upper tiers), optionally with middle tier (a few in the middle)
Cache Reserve <- R2, last
So Requests could go
Local -> Tiered Cache Middle -> Tiered Cache Upper -> Cache Reserve -> Origin

Rich•4/30/24, 4:05 PM

Ok thanks -- I guess rolling our own cache reserve with R2 directly would be a bit clumsy as CF cache purging obv wouldn't work.

I wonder, does CF intend to add support for Cache Reserve and Tired Caching when using the Cache API eventually?

Chaika•4/30/24, 4:08 PM

don't think I've heard anything about it, and it's been this way since Cache API came out in 2019. You can use the fetch() api to use tiered caching/cache reserve, but would have to have an endpoint to fetch of course

Chaika•4/30/24, 4:12 PM

well I imagine some of it is just simple limitations

Tiered Caching Smart requires an IP/geolocation to use, cache api doesn't give it one.
I know Cache Reserve is also part of "Pingora" which their connecting to origin software, so a step outside of the normal stack/where workers run
plus Cache API is completely free

Fetch() goes through the normal outgoing flow

Rich•4/30/24, 4:29 PM

hmm I see. I guess the Cache API could accept an IP as a header -- but yeah I suppose the fundamental difference between fetch and the Cache API is the Request passed to the latter doesn't necessarily point to an actual origin -- could be new Request("https://this.doesnt.exist.at/all")new Request("https://this.doesnt.exist.at/all") .

Given our cache key isn't really a RequestRequest, I wonder if we're better off ditching the Cache API and implementing a more standard key / value cache with R2 or KV

hi, if I store assets into cache using the cache api using a worker and purge the zone cache where this worker has a route, will these files also be purged?

Adi•5/1/24, 1:29 AM

I got seen zoned on general discussions with this question, figured I'd ask here

. Would love some clarification.

Quick question about the smart placement limitation on RPC service bindings. Is that temporary? Or is it a limitation that is expected to be around for a while? Not looking for a timeline, just some confirmation the vision for RPC.

I've been told it should purge so long as you use caches.defaultcaches.default (rather than caches.opencaches.open) -- however we've been unable to get purging to work sadly.
