@Chaika I want to be able to send my event notifications to AWS Lambda for now as I have more experience there. Do you happen to have any links to tutorials on how to do that?

I haven't played around with r2 event notifs yet, but iirc they just use a normal Queue.
https://developers.cloudflare.com/queues/reference/pull-consumers/
You could have a queue customer worker which fetches your lambda and passes the info, or you could even use the HTTP Pull API to have the lambda pull the queue

https://developers.cloudflare.com/r2/examples/upload-logs-event-notifications/#log-and-store-upload-events-in-r2-with-event-notifications
There's a guide here on getting started. You could modify that worker they give as an example writing to R2, to fetch(...) your aws lambda endpoint instead and pass the messages

This example provides a step-by-step guide on using event notifications to capture and store R2 upload logs in a separate bucket.

You are correct

I recently implemented them for my own project

Thanks very much for the tip. That sounds logical. BTW, I previously followed the tutorial you reference and it is excellent. Very clear and easy to follow.

Chaika•4/4/24, 5:44 PM

What do you mean "so many operations"?

Chaika•4/4/24, 5:44 PM

132 Class Bs would cost you = $0.00004752 ((0.36/1,000,000) * 132)
59 Class As would cost you = $0.0002655 ((4.50/1,000,000) * 59)
0.00004752 + 0.0002655 = 0.00031302
1/ 0.00031302 = 3194. It would take you doing that 3194 times to be charged a dollar in use. and that's excluding the 10 mil Class Bs you get, and 1 mill Class As.

CChaika What do you mean "so many operations"?

Neyunse•4/4/24, 5:47 PM

I haven't used my R2 yet, but I have Class A and B Operations

Chaika•4/4/24, 5:47 PM

Right, just looking at your buckets in the dashboard/files/etc will cause Operations to be done

Chaika•4/4/24, 5:48 PM

Class A operations

Class A Operations include ListBuckets, PutBucket, ListObjects, PutObject, CopyObject, CompleteMultipartUpload, CreateMultipartUpload, ListMultipartUploads, UploadPart, UploadPartCopy, ListParts, PutBucketEncryption, PutBucketCors and PutBucketLifecycleConfiguration.

Class B operations

Class B Operations include HeadBucket, HeadObject, GetObject, UsageSummary, GetBucketEncryption, GetBucketLocation, GetBucketCors and GetBucketLifecycleConfiguration.

https://developers.cloudflare.com/r2/pricing/

Chaika•4/4/24, 5:49 PM

The dashboard does a bunch of those. It lists all of the buckets, lists all of the objects/files, you likely created a bucket, if you upload a file via the dashboard. Class Bs would be getting file information, bucket information, bucket location, lifecycle config, etc

Neyunse•4/4/24, 5:52 PM

I understand, now I know where the operations come from. Thank you! I thought they increased if I performed any action outside of RS, for example external requests.

dave•4/4/24, 6:30 PM

for a single part file, will CopyObject keep it as a single part file in the new location?

dave•4/4/24, 6:35 PM

x-amz-copy-source-if-match

x-amz-copy-source-if-match

supposed to be the etag with quotes or without quotes?

dave•4/4/24, 6:39 PM

and it's just

x-amz-copy-source: dest_bucket_on_r2/filename.txt

x-amz-copy-source: dest_bucket_on_r2/filename.txt

right?

dave•4/4/24, 7:28 PM

Is there a way to only allow a Cloudflare Worker to use an R2 token with IP filtering?

Karew•4/4/24, 7:31 PM

I would create a specific token just for your Worker

KKarew I would create a specific token just for your Worker

dave•4/4/24, 7:56 PM

yeah I already did that

Kkian Yes

dave•4/4/24, 8:08 PM

hmm, is there a similar trick to use

If-Unmodified-Since

but with CopyObject?

kian•4/4/24, 8:09 PM

thank you!

kian•4/4/24, 8:10 PM

All the S3 extensions are on that page

dave•4/4/24, 8:10 PM

r2_copy_headers.set("cf-copy-destination-if-unmodified-since", "Thu, 01 Jan 1970 00:00:00 GMT");

r2_copy_headers.set("cf-copy-destination-if-unmodified-since", "Thu, 01 Jan 1970 00:00:00 GMT");

So that'll enforce write-once only?

yeah, looks at my metrics now, looks like you're right. I'll leave it running for a bit and see if it changes

hendrik•4/5/24, 11:30 AM

is traffic generated through r2 shown in the domain analytics?

hendrik•4/5/24, 11:30 AM

as well as requests?

hendrik•4/5/24, 11:33 AM

okay thanks

Venkat Dinavahi•4/5/24, 12:48 PM

Hey folks looking for tips/advice on an architecture similar to what imgix does, except adapted to a different use case.

We have an app (cloudflare worker) where you can request files in urls like:
/storage/organizations/clcjbt6kr00021pp49d3e5gtm/folders/clrxn7fgp0000zatqagz06s7c/mydoc.png

Venkat Dinavahi•4/5/24, 12:49 PM

We'd like to perform certain transformations on these files. I liked the cloudflare is doing with images:
https://developers.cloudflare.com/images/transform-images/transform-via-url/

Except it would be different stuff like:

Convert documents to PDF
Get OCR data

Cloudflare Docs

Transform via URL · Cloudflare Image Optimization docs

You can convert and resize images by requesting them via a specially-formatted URL. This way you do not need to write any code, only change HTML …

Venkat Dinavahi•4/5/24, 12:50 PM

The idea is to build something into the url structure that makes processing more seamless for the frontend and caches the results in R2

Venkat Dinavahi•4/5/24, 12:52 PM

in their example they have something like:
/cdn-cgi/image/width=80,quality=75/uploads/avatar1.jpg

Is there a reason they choose to have those options in the path vs. as a query parameter?
Anything I should keep in mind regarding headers or the server-side implementation on cloudflare? Any examples out there to look at?

DanVilela•4/5/24, 2:02 PM

Hey guys, I just allowed public acces to my R2 bucket but still getting an 404.. Anyone know whats up? Couldnt figure out by the doics

DanVilela•4/5/24, 2:13 PM

I see. thanks!

VVenkat Dinavahi in their example they have something like: /cdn-cgi/image/width=80,quality=75/up...

zach•4/5/24, 6:33 PM

paths can always be cached and querystrings can be ignored for cache

zach•4/5/24, 6:34 PM

a URL is a resource locator — it tells where an exact resource is. If the resource is different even with the same path, is it a uniform resource locator?

zach•4/5/24, 6:34 PM

(tl;dr is that it's probably for caching

Busslina•4/5/24, 6:43 PM

Hi guys. Seems not possible to create a folder manually

Busslina•4/5/24, 6:43 PM

Busslina•4/5/24, 6:46 PM

In order to adapt my new r2 items to the same path I have stored in my db I had to rename my windows folder, then drag and drop. Seems a little trickier
