Mongodb offers change events that you can use to know when entities are deleted, then react upon deletion

O

omar4289•10/16/23, 8:10 AM

I would also suggest that you have cron jobs, every once in a while to delete unreferenced files

O

omar4289•10/16/23, 8:13 AM

You could also use some queues that you trigger from your application when entities that references a file has been deleted/updated

You kind of want to structure it the other direction. You want the object in Mongo to be the “truth” or the record of having the file. When you want to delete the record you delete the Mongo object and the file in R2 as part of the same process. The Mongo object has a copy of the R2 key. You should not have any orphaned R2 files if you’re strict about this, and it will also make it so you don’t have to list your R2 files frequently.

Hi! is the URL signing operation class A or class B for purposes of billing?

If i want to create an application, where you can upload images and videos. Should i then use R2, or Stream and Images?

The videos dosen't have to be streamed, but i still need thumbnails (the first frame of the video).

K

kian•10/16/23, 10:04 AM

R2 will be much cheaper than the other options, but it is just object storage - what you store is what users will get. No re-encoding, different qualities, etc.

K

kian•10/16/23, 10:04 AM

Thumbnails would need to be created by yourself, i.e with ffmpeg

Hello, I can't remove a custom domain from a bucket. It says "The specified bucket does not exist. (Code: 10006)", which seems incorrect, since I'm literally in that bucket's settings. I mistakenly added my app's subdomain there and thus made it inaccessible. Please help!

digitalpoint•10/16/23, 3:13 PM

While not a solution to being unable to delete it, Cloudflare really should prevent users from adding a public domain to an R2 bucket that already has a DNS entry. I’ve had multiple users accidentally put the root of their domain as their public domain for an R2 bucket which of course kills their site until they remove it and restore the DNS entry the action overwrote.

Hi, I also ran into this problem where I can't remove the domain from public access because it says 10006 error. What to do in this case?

ZZora To be fair, it does warn you before you confirm the action

D

digitalpoint•10/16/23, 4:46 PM

Ya, it does show what it was and what it will become, however even with that I've ended up with 10-15 users overwriting DNS records on accident. I just think it would make more sense to force a user to delete the existing record first. That way they have to take a clear action vs. users just blindly clicking "okay". I wish users read more, but it's unfortunately not the case.

Z

Zora•10/16/23, 4:47 PM

That's true, like how if you want to remove the R2 bucket entry in the DNS you have to go to the R2 dashboard, the same could be done for that

D

digitalpoint•10/16/23, 4:48 PM

Usually it's users trying to connect the root of their domain, thinking it's somehow allowing access from their domain (like some sort of wildcard maybe?)

D

digitalpoint•10/16/23, 4:51 PM

I did end up plopping in a "suggested" subdomain by default for my UI and for the users that blindly click, it helped. However, I still think it would make sense to throw an API error if the public domain they choose already exists in their DNS.

T

Tomas•10/16/23, 5:02 PM

yeah I wasn't really paying attention to the the message in the R2 UI. Requests from my app were getting Access Denied response, so I thought I need to "allow" the domain somehow.

Your r2 binding is commented out. Also, the way you access it depends on if you're using Service Worker or Module Worker format

C

Chaika•10/16/23, 6:50 PM

If you don't know which format you're using, if you are using

addEventListener

addEventListener

addEventListener

addEventListener, it's service worker and bindings are globals. If you have

export default {
  fetch(request, env, ctx) {

export default {
  fetch(request, env, ctx) {

export default {
  fetch(request, env, ctx) {

export default {
  fetch(request, env, ctx) {

It's a module format and it's on env

When you run dev, it prints out the bindings your worker uses, do you see r2's?
