just to be sure here james, they said that as soon as your worker starts responding to the request, the timer stops

PhatsoOP•7/3/23, 8:21 PM

so the time for the file to actually get to the client is not included in that duration cost

i don't think it's how worker work

this one here

PhatsoOP•7/3/23, 8:23 PM

quick question: could you maybe make it a public bucket, hook it up to a custom domain and then access the files that way? I thought that was a solution for this kind of thing.

Unsmart•7/3/23, 8:23 PM

If your files are public yes

PhatsoOP•7/3/23, 8:23 PM

does a presigned url imply that they aren't public

Unsmart•7/3/23, 8:23 PM

yes

PhatsoOP•7/3/23, 8:24 PM

i see

Unsmart•7/3/23, 8:24 PM

I mean you could make presignedurls public but a presigned url requires generation from a secret key

PhatsoOP•7/3/23, 8:24 PM

right, that makes sense

kraftriver•7/3/23, 8:25 PM

well i don't get it then. to download something from a server / serverless function. Something need to be running isn't it? if the fetch request take 0ms, what about the response time to the user? it's not counted in the workers duration cost ?

PhatsoOP•7/3/23, 8:25 PM

nope, it's not

PhatsoOP•7/3/23, 8:25 PM

so @james8313 i believe this means that you'd only be billed for the time it takes the worker to retrieve the data from r2. once it starts responding with the data, the timer stops and you won't be billed for worker time anymore for that request

kraftriver•7/3/23, 8:26 PM

Okay, well, i'll try and see then.

PhatsoOP•7/3/23, 8:26 PM

r2 returns a readable stream, can you return that readable stream without the worker having to actually retrieve all of the data into memory

PhatsoOP•7/3/23, 8:27 PM

nice so that's nearly instant then

PhatsoOP•7/3/23, 8:27 PM

okay so not only is it a good way to do it, it's the way to do it

PhatsoOP•7/3/23, 8:28 PM

is this what the mandalorian guy was talking about

cloudflare r2 retrieval strategies

kraftriver•7/3/23, 8:28 PM

and it's the same for 1GB file or whatever size of file it is ? It seems so hard to get my head around it

PhatsoOP•7/3/23, 8:28 PM

cloudflare pricing is insanely generous, it lets people make extremely powerful apps without breaking the bank. it's amazing

Walshy•7/3/23, 8:29 PM

Yep

Walshy•7/3/23, 8:29 PM

Want to stream a TB file or a 1 MB file? Still the same

PhatsoOP•7/3/23, 8:29 PM

i guess one way to think about it is that once the worker starts returning the data, the actual worker code isn't running anymore, it's just a data stream

PhatsoOP•7/3/23, 8:29 PM

like your js code has effectively stopped running

Snippets

kraftriver•7/3/23, 8:29 PM

"and a isolate could serve multiple requests at once" really ? i always thought they could serve only 1 request at once and create more instance for every new concurrent request happening at the same time

kraftriver•7/3/23, 8:33 PM

kraftriver•7/3/23, 8:36 PM

Snippet is so awesome can't wait to use it

PhatsoOP•7/3/23, 10:15 PM

Why are some R2 features seemingly locked behind the S3 API?
Location hints, for example, can only be done in the dashboard or using the

S3

S3

API

Object lifecycles too.

I thought R2 was supposed to be an S3 alternative, why is it still mooching off the same tools?

kian•7/3/23, 10:31 PM

The dashboard is using the only other option, the Cloudflare V4 API.

kian•7/3/23, 10:31 PM

Wrangler could implement it too - since it's the same API routes and payloads - it just, well, hasn't.

kian•7/3/23, 10:32 PM

The dashboard can be changed at any time along with the APIs so stuff tends to not land in Wrangler (or the publicly documented API) until they're stable - but some things that have existed for years, like Bot Fight Mode, also aren't documented so take that with a grain of salt.

Unsmart•7/3/23, 11:24 PM

try to generate a new token, the one you are using mightve expired or maybe is in a weird state for some reason

SSid Oh, er let me look for it

PhatsoOP•7/3/23, 11:34 PM

What's the liklihood of that getting re-proposed/merged?
Currently I'll have to do some really wacky stuff to make it happen where/when I need it :(

mrmachine•7/4/23, 12:17 AM

what is a GB-s in terms of unbound worker billing? (we're using a worker in front of R2 which is often returning a response from cache.match()) ... is unbound a better plan, given its 15c per million requests vs 50c per million for bundled? but bundled includes 10m to start vs 1m to start for unbound?

Old3n•7/4/23, 5:20 AM

Hi! I want to implement pre-signed urls so that it expires after some time, similar to what we can do with S3.
Like this:

https://cdn.mydomain.com/myfile.mp4?token=dsh90sd0f9h&expires=1688455089

https://cdn.mydomain.com/myfile.mp4?token=dsh90sd0f9h&expires=1688455089

Is it possible to do with R2, and how?

Alex•7/4/23, 7:32 AM

I was researching this topic too but the GB-s is a bit of a vague concept. I'm guessing the wall time is another metric from the Median CPU time the dashboard is giving us?

For example: https://screen.bouma.link/jXf3b8Cs5DL6ky8K7kZ0

I believe this costs around 0.50$ (because 1 million over the 10M) on the bundled plan.

But if I were to choose unbound it would cost 11 * 0.15$ and ~8 * 12,50 for the GB-s right?
So that would mean around a 100$ instead?
