I don't fully see the relationship with multipart upload in the above? Multipart upload is when a file is too large (say 1GB) to send in one go (buffer size, bad network, ...), so you upload it in different parts (say 1000 parts of 1MB). The latest worker typings have support for multipart upload on R2 - https://developers.cloudflare.com/r2/api/workers/workers-multipart-usage/

yes, but restrictions (such as each part must be the same length, besides the last) prevents me from using it. i need to handle this custom

with the above i can easily keep track of what specific parts have been uploaded

otherwise, i don't know of an efficient way to do it

Hey, I added a lifecycle rule which is deleting over 100TB of objects (each object is in the order of 50gb). I'm finding the web UI is mega unresponsive, but I can seemingly retrieve files outside the lifecycle policy from the public endpoint. Is there much risk to the files outside the lifecycle policy? I need to make a similar change to another bucket which can impact our SLA so I thought I would check here first

I'm not sure I understand, but a deletion lifecycle rule will not affect objects that don't "match" the policy

Yes, but given I was seeing multiple errors and very slow loading from the web ui, I grew concerned that triggering such a large GC may have other performance implications for the bucket

So the UI being slow isn’t correlated to actions on your bucket, I’ll check out what’s going on with the UI. If you want to confirm if your lifecycle rules are correctly configured, you can try and fetch them via the S3 API as well

Hi guys, I am building a mobile app were i need to store and retrieve images. We are using R2 for that in golang server (gin framework). I have created a bucket and give edit permission and got api-key and secret. I am using cloudfare-go sdk, but I am stuck since yesterday on how to upload the image using the sdk , i tried many method likes uploadimages() but nothing worked. Can someone please help me?

I doubt there is any method in the SDK to do it

You'd be better off using aws-sdk-go

I'm trying to add a custom domain to an R2 bucket but when I click on

Connect Domain

, I see the error

No route for that URI (Code: 7000)

, even before I start typing a domain (and it keeps erroring after I type a domain). Anyone run into this before?

I can reproduce, let me raise this. Thanks for the report

Raised and the team is on it. Thanks again for reporting

Thanks James!

btw to add for context, this was raised as https://www.cloudflarestatus.com/incidents/n8b4zhdkvsb9 - thank you @robert for reporting!

@robert this should now be resolved, please reload the dash and you should be good to go 🙂

Wow amazing, thanks y'all, it worked!

Sweet 😄

Is there any ETA for per-bucket tokens? We want our data suppliers to upload directly to R2 (can't use browsers because it's many TB per dataset), but for that to work we need tokens that only have write access to a specific bucket

Hello, for some reason under my R2 bucket, under setting the 'Public Access' option is not available. Even after adding custom domain public access in not enabled. Please help

Your custom domain says it’s active. That is one method of public access.

If you're expecting it to work like a file tree when you visit the domain, or show an index.html when you visit

/

, that doesn't happen

If you visit a specific asset in the bucket that'll work fine though

That makes sense. I am a newbie hence the confusion. Thank you for your time @Skye and @Karew

Can a single bucket be bound to multiple workers?

Yep

Yes it can

We are experimenting with R2 as a replacement for S3 for some of our asset distribution, and I have a few questions that you might have good answers for! When you use a custom domain, and get default caching of assets implicitly, are you charged for the egress from the cache? It's unclear from the documentation in [1][2] if that's the case. Also related, does

Cache-control

metadata on the R2 objects affect said cache hit rate? (I'm assuming yes) And finally, when the cache is warm and there's a hit, do read operations served from the cache, account as class B operations over R2? Thank you so much!
