Bbun https://www.jsdelivr.com/globalping

Oleg Isonen•2/18/24, 7:33 PM

global ping doesn't even try to fetch a specific resource

bunOP•2/18/24, 7:33 PM

its not a ping its a http request

Oleg Isonen•2/18/24, 7:33 PM

CAN'T because it doesn't work with R2 apparently

bunOP•2/18/24, 7:34 PM

TTFB is what matters here

Bbun its not a ping its a http request

Oleg Isonen•2/18/24, 7:34 PM

to the document, and we are not discussing that, we need that test to the css ressource I mentioned and that tool doesn't let me specify the ressource

what's a normal host? our static ressources are on R2

bunOP•2/18/24, 7:35 PM

it does? as i showed in the screenshot

Oleg Isonen•2/18/24, 7:36 PM

so you want to set up a proxy for R2 so that cloudflare can use tiered cache

Oleg Isonen•2/18/24, 7:36 PM

I hear this solution from @istarkov and I am like "wtf"

Original message was deleted

Oleg Isonen•2/18/24, 7:37 PM

I am saying we can't, its not a toy project, we need R2, otherwise we have to migrate to S3 all static ressources

Oleg Isonen•2/18/24, 7:37 PM

right, I honestly love CF, politics here play a role, and I would hate my guts for going to AWS

bunOP•2/18/24, 7:38 PM

the results i showed earlier were for that css.

the results for the document itself are 500-1000 ms

Oleg Isonen•2/18/24, 7:38 PM

I am rooting for CF to succeed and I just can't wrap my head around the fact that this is such a simple issue that can't be fixed within CF ecosystem

Erisa•2/18/24, 7:40 PM

To my knowledge Tiered Cache (at least Smart tiered) still won't work since the origin is still an anycast Cloudflare IP

bunOP•2/18/24, 7:41 PM

thats true

bunOP•2/18/24, 7:42 PM

maybe put document files in KV, and every other asset can be served from R2

The HTML document in question isnt even cached

Original message was deleted

Oleg Isonen•2/18/24, 7:42 PM

so using a worker as a proxy

Oleg Isonen•2/18/24, 7:43 PM

would be amazing if that works really well, but also

Erisa•2/18/24, 7:43 PM

What testing tool is that?

bunOP•2/18/24, 7:43 PM

https://www.jsdelivr.com/globalping

bunOP•2/18/24, 7:43 PM

although it doesnt ping, it actually makes a request and downloads the resource. displaying vitals for each of those

Erisa•2/18/24, 7:44 PM

Well it does whatever you tell it to

Erisa•2/18/24, 7:44 PM

I suspect it may be prohibitively expensive

Erisa•2/18/24, 7:45 PM

Ah, not bad

Ivan Starkov•2/18/24, 7:47 PM

Tried, doesnt work if domains are on single account, gonna try with different accounts

Unsmart•2/18/24, 7:48 PM

The annoying part of trying to do tiered cache on your own with DOs would be mapping all the colos to what location it should load a DO from

Ivan Starkov•2/18/24, 7:50 PM

Yep tiered, just poking around, sometimes somethings are working just with different accounts etc.

Oleg Isonen•2/18/24, 7:51 PM

So we should create a separate CF account to create a proxy that will then let our main account use tiered cache

Ivan Starkov•2/18/24, 7:51 PM

Not so hard

bunOP•2/18/24, 7:51 PM

can anyone explain wtf is tiered cache? ive read the documentation and it kind of makes sense, but i dont get what is this whole discussion is about? how is another CF account or a proxy going to help with anything

Ivan Starkov•2/18/24, 7:52 PM

It does work only with data from your origin

Ivan Starkov•2/18/24, 7:52 PM

It doesnt work with r2

Oleg Isonen•2/18/24, 7:53 PM

the way I understand it it contains multiple different strategies on how to cache the data close to the edge

Ivan Starkov•2/18/24, 7:53 PM

With proxy you can put r2 on your origin

Erisa•2/18/24, 7:57 PM

One messy but workable solution could be to shard data between multiple R2 buckets with different region hints and then route each uncached request to the closest bucket. Only issue would be multiplying your storage costs and increased complexity

bunOP•2/18/24, 7:58 PM

are there no plans of adding tiered caching for R2 ?

Erisa•2/18/24, 7:58 PM

There are plans

Erisa•2/18/24, 7:58 PM

It is a current limitation, not a permanent one

Oleg Isonen•2/18/24, 7:59 PM

yeah this is something we also considered with @istarkov I wonder how bad this solution really is

Erisa•2/18/24, 7:59 PM

I can tell you I've seen customers implement it before and while the implementation is a bit messy they generally are pleased with the end result

Erisa•2/18/24, 7:59 PM

Hopefully in future that particular limitation with Tiered Cache can be sorted out for good

the R2 team are aware of these shortcomings and working on solutions, if you have an Enterprise account I strongly recommend reaching out and getting it filed as a feature request to speed that up. If not, hang tight
