I understand intermittent failure is expected in a system like R2, but wondering if anyone has ideas

I understand intermittent failure is expected in a system like R2, but wondering if anyone has ideas for how to reduce these error rates, or if anyone from CF can take a look

Unsmart•10/28/23, 12:27 AM

What is the error rate you get with that? @Colin

From my own testing it seems the error rate it seems quite low

ColinOP•10/28/23, 12:27 AM

oh yeah it's definitely quite low, I see it at ~1%

ColinOP•10/28/23, 12:28 AM

but shows up in logs often enough I'd figure it's worth seeing what's going on

Unsmart•10/28/23, 12:28 AM

1% seems pretty high, whats your upload volume?

UUnsmart 1% seems pretty high, whats your upload volume?

ColinOP•10/28/23, 12:34 AM

I’d estimate we have ~80k object uploads per week

CColin I’d estimate we have ~80k object uploads per week

Unsmart•10/28/23, 12:39 AM

Hmm R2 should be able to handle 80k uploads per week just fine I do ~40k per day with only a 0.08% failure rate. Do you happen to know the average size of the files and do you know if errors happen more often in certain regions?

ColinOP•10/28/23, 12:41 AM

Yeah it's definitely not a crazy high volume, so I'm not super sure why

ColinOP•10/28/23, 12:41 AM

Average size of the file is <=50kb; unfortunately don't have a per-region breakdown

ColinOP•10/28/23, 12:42 AM

I'm wondering if it's users' connections timing out mid-stream or something

Unsmart•10/28/23, 12:50 AM

That could be possible not sure. 50kb is pretty small and should upload really quick so would be surprising if that many had their internet cut out during that

Hi Team, I need some help with building a custom hls streaming service using R2. I'm aware of the streaming service provided by cloudlfare but i want to build a custom one on R2. I need help to implement streaming of multiple hls files through r2. Do i need to create a presigned url for all the files or is there a better way considering my bucket is not public? Please help!!.

RE: r2

Here's what I ended up doing. When the user changes their profile photo, I update a field in my database called

profile_changed

profile_changed

.

Then, in my handler if that photo is requested again, I check to see if it's more than 15 minutes since the last profile change. If it is less than 15 minutes, I use a refreshed string to fetch the photo Insert the newest version of the photo. Otherwise, I use whatever is in cache right now. I hope that is the most recent photo.

Sid, how long is a dynamically generated image pulled from r2 lifespan? Do I need to bump this up to an even higher time.? Like a day?

Sid•10/28/23, 4:11 PM

I don't think I understand, R2's objects don't have a lifespan (R2 doesn't cache on it own). I think what you may need to adjust is the cache's duration

alexandernst•10/28/23, 6:11 PM

Is R2 throttling uploads (via API) in any way? I'm experiencing what is looks like throttling. I wrote a simple script that sends files to R2 in batches of 100, and after successfully sending 500 o 600, the network traffic stalls for a minute or so.

Unsmart•10/28/23, 6:36 PM

R2 does not have any throttling. I would probably wager that your ISP might be throttling your data in that case

I thought that, but I get exactly the same result when trying to do the work from a hetzner machine in germany (I'm in spain)

I'm getting the following error when trying to set the cors policy for r2 -

I've got this weird issue with listing objects. The function in the screenshot used to return objects in our bucket, but simply doesn't now. An example object name that exists in our bucket is

1001_x2KasaV5awqZVhPekJvwHU_1696199791682_0.mp4

1001_x2KasaV5awqZVhPekJvwHU_1696199791682_0.mp4

, but providing the function with an account ID of

somehow offers 0 results.

kian•10/28/23, 11:42 PM

Is the file stored in the bucket root?

ColinOP•10/28/23, 11:50 PM

I think so?

kian•10/28/23, 11:57 PM

Are you running the code with wrangler dev?

tt2468•10/29/23, 12:07 AM

Normal wrangler afaik

tt2468•10/29/23, 12:07 AM

I do know the bucket itself is correct, since the

.get()

.get()

method for specific objects works as expected

tt2468•10/29/23, 12:37 AM

Looks like

delimiter

may have been the cause

Hello, i am unable to connect R2 bucket to custom domain, Status badge staying at initializing state. but conneting to another domain works well. also worker routing to custom domain is working well. any advise?

gluck•10/29/23, 12:53 PM

Hello, I am connecting to R2 from php, when creating a presigned url the generated url seems fine but browsing to it shows this error:
<Error>
<Code>NoSuchKey</Code>
<Message>The specified key does not exist.</Message>
</Error>

the key and secrets are fine as upload to bucket works fine

alexandernst•10/29/23, 6:37 PM

Is there a way to copy files from one bucket to another without downloading & uploading the files?

Erisa•10/29/23, 7:12 PM

If you had Tiered Cache enabled with DO then thats probably the discrepency. Currently R2 doesn't support tiered cache so the cache is per-colo and there are a lot of those.

Erisa•10/29/23, 7:12 PM

That's something that will hopefully be ironed out in future

Erisa•10/29/23, 7:18 PM

https://dash.cloudflare.com/?to=/:account/:zone/caching/tiered-cache is what I'm referring to, having it enabled would increase cache hit rate on DO but not on R2 due to current limitations.

If you have a Pro plan or higher you can view detailed cache analytics to find out where they're coming from. If not, what does your cache rule look like?

Check your network tab and see how long it takes to download the files (When reading videos from r2, you will have to download all of the content before you can read it)

omar4289•10/29/23, 8:22 PM

If that is inconvenient (Which it is most of the time), then you will need to have it as a stream
