If you're offering public files for users to download, attaching a domain to R2 will make it a lot faster, you get to use the full Cloudflare CDN/proxy

KarewOP•3/27/24, 8:30 AM

Cloudflare should also be accelerating your Backblaze B2 files if you're already doing that, though

Tangenius•3/27/24, 9:08 AM

Can anyone help me get some insight on this?

Tangenius•3/27/24, 9:09 AM

Well I tried the regular way aswell but then realized that wouldn't work during development

Tangenius•3/27/24, 9:09 AM

So I need that to be able to test and then when I deploy for real I won't use that

Tangenius•3/27/24, 9:09 AM

Except if you know a way to avoid using that

Tangenius•3/27/24, 9:10 AM

You mean with a local dns or something?

Tangenius•3/27/24, 9:10 AM

Oh no a subdomain dedicated for testing

Tangenius•3/27/24, 9:10 AM

I see

Tangenius•3/27/24, 9:11 AM

And connect that to R2 to use that as s3 gateway?

Tangenius•3/27/24, 9:13 AM

Oh really, I need full s3 compatibilty because I want to use that as my storage backend for files. Is R2 not the right product for me then?

Tangenius•3/27/24, 9:17 AM

That's what I tried at first without succes, which made me expect it would only work when requests came from a CF ip but probably DNS needed some time to update after I created my bucket?

Tangenius•3/27/24, 9:17 AM

Now it seems to work, thanks

mickiewicz12•3/27/24, 12:21 PM

Hi, does the rate limit/max concurrency upload number apply to the entire account or to single bucket?

irohaforever•3/27/24, 2:01 PM

Thanks, I will change to R2 soon
I didn't want DNS only setup because balckblaze's IP would be exposed.

Chaika•3/27/24, 4:54 PM

bodybody is a readable stream. If you want the text, you can do
var txt = await objectFile.text()var txt = await objectFile.text()

taylorodette-WUMP•3/27/24, 4:55 PM

alright, thank you

taylorodette-WUMP•3/27/24, 4:56 PM

Does R2 have append mode to write files?

Chaika•3/27/24, 5:00 PM

S3 API doesn't support appending, nor does the workers api

taylorodette-WUMP•3/27/24, 5:13 PM

OK, thanks

hi guys, i have a small issue with a website that i tried to serve files for, via r2 / s3 bucket, i had some issues, and i deleted the bucket, but before i removed the domain from the allowed domains, and now i am unable to load the domain, i get DNS _PROBE_FINISHED_NXDOMAIN when i try to load the page

PCDoctorSM•3/27/24, 6:41 PM

i cleared cache but with no luck

PCDoctorSM•3/27/24, 6:54 PM

nevermind, found the problem, it seems that when i removed the bucket , it deleted the A record for that subdomain used for bucket.

Hello, I’m loving R2 and its pricing model. I have a question: I made a cloudflare account with my personal email, and my project has turned into a small business. I want to move my account to my business email cloudflare account. I linked the accounts and am an owner of the r2 “project” (not sure what they’re called not really projects sorry). But I have to access it by logging in with the new email and then clicking into my old email which the new email have access to. I want to totally remove the access from the old email and only access via the new email. Is this possible? Thanks!

Erisa•3/27/24, 8:20 PM

The account name being an email address is just the default, you can change it something more descriptive: https://developers.cloudflare.com/fundamentals/setup/account/customize-account/account-name/
And if the new email is a Super Admin you can revoke access from the old email

i'm uploading map tiles to R2 and i'm currently debating the directory structure <output_directory>/{zoom_level}/tile_{x}_{y}.<format><output_directory>/{zoom_level}/tile_{x}_{y}.<format> vs <output_directory>/{zoom_level}/{x}/{y}.<format><output_directory>/{zoom_level}/{x}/{y}.<format>. are there any performance issues when a single directory has 100k objects?

marcusroar•3/28/24, 6:37 AM

Thank you! However when i click R2 from my new account dashboard it shows an uninitialised R2 product. It’s only when i go into the old account via the dashboard home page (i can see both accounts there when I log into the new account) that I see the r2. Anyway to transfer? I tried contacting support but I think they thought I was trying to transfer a domain which I don’t think this is.

Pro has Custom Error Responses, which are only configurable via the API but can be used to make a custom 404 page yea

alternatively, you can use a worker, but you'd be paying worker invocation/request for every incoming request, cached or not

Kkian There’s caching of the API creds for 60s iirc so it might be a little faster

dave•3/28/24, 3:24 PM

is that caching done where the R2 bucket is stored, or at the edge of wherever the request is coming from?

If I'm signing files from multiple buckets from the same Worker, it makes sense to use the exact same R2 token for all signatures, right? (Since the API credentials would be cached for everything beyond the first request.)

Ddave I don't think there's any way, but is it possible to have two presigned URLs be ...

blocking the referrer will work unless others disable the referrer header with noreferrernoreferrer

Zora•3/28/24, 5:05 PM

then you have to block blank referrer headers but it gets messy after that
