I would use durable objects over R2 for a KV store thats cheaper and not replicated

Yes. You can either hydrate and change it on the client, or (probably the better way) do it in a Function which is the Pages equivalent of a Worker: https://developers.cloudflare.com/pages/platform/functions/

Sounds like an good option because I plan to store small objects in it, I want to confirm how the duration is billed (no websockets), say I want to read an object once and then once again 1 second after, do I get billed ~1 seconds or just the split milliseconds that the DO was actually working on those reads ?

UnsmartOP•5/12/23, 12:36 AM

You’ll only be charged by the ms. The duration billing for DOs when all you do is storage ops is so insanely negligible that I don’t even count it normally

Ian•5/12/23, 12:41 AM

Got it thanks, there is a request limit of 150rps per DO, there will be a few DOs that is potentially being requested a lot, it seems that I can use the Cache API for that, I don't read article regarding pricing or rate limits, want to confirm that it's free and does not have an upper limit ?

UnsmartOP•5/12/23, 1:48 AM

Cache is free for unlimited RPS.

#durable-objects maybe?

I can only think of https://where.durableobjects.live/json, which is an unofficial list (with extra data about DOs)

UnsmartOP•5/12/23, 2:43 PM

- yes it should afaik
- you can use the S3 API which doesnt require bindings

UnsmartOP•5/12/23, 2:45 PM

No clue, I know its a bit slower because of the authentication step but I wouldnt think its too different

UnsmartOP•5/12/23, 2:47 PM

I doubt you ever get a full list of those and they change because cloudflare adds new colos

DaniFoldi•5/12/23, 2:48 PM

as exhaustive as it can get, I recommend logging unseen values to see if you need to update your list (in case they add new colos as Unsmart mentioned)

dave•5/12/23, 2:53 PM

since you straight up can't create a bucket with the R2 service bindings AFAIK, hard to compare the perf

UnsmartOP•5/12/23, 2:55 PM

queues

Dynamic bindings have been talked about before for all products D1/R2/Queues/etc but no clue where they would fall on their roadmap.

dave•5/12/23, 2:55 PM

I don't think this is a good recommendation for @lord_krondor, but what we have planned, is making "virtual" buckets on top of "real" buckets.

Kkrondor Virtual buckets sounds like a great idea. For context I’m trying to implement us...

dave•5/12/23, 3:00 PM

basically our plan to have each virtual bucket map to a folder in a "real" bucket.

Kkrondor I’d love that — that’s essentially the solution I came up with

dave•5/12/23, 3:04 PM

it does add some complexity though, the main reason we're doing it is because we would run into max bucket limits quickly with some S3 providers.

dave•5/12/23, 5:46 PM

are you returning the non-cloned responseresponse right away?

dave•5/12/23, 5:49 PM

hmm iirc I had this issue too, don't think I found a good workaround. I ended up doing two fetches IIRC

Hello, I’m Allie!•5/12/23, 11:31 PM

Before, and you can see the flow in the rules dash
Yes, but only if you only have Workers on your domain

Ian•5/13/23, 2:20 AM

does workers kv charge for these cached requests ?

Chaika•5/13/23, 2:27 AM

Yes, it counts as a KV read regardless if it's cached locally or fetched from one of the two data stores

Ian•5/13/23, 2:32 AM

But if I cache it with the Cache API, then it's not counted ?

Ian•5/13/23, 2:33 AM

I can accept an outdated data

Ian•5/13/23, 2:33 AM

for up to an hour

Chaika•5/13/23, 2:33 AM

Indeed, Cache API is free. A community champ made a library to do exactly that if it helps called BetterKV: https://flareutils.pages.dev/betterkv/

BetterKV | Flareutils

Small Utilities and little goodies that make developing with Cloudflare easier and faster.

Ian•5/13/23, 2:34 AM

nice

Hello, I’m Allie!•5/13/23, 7:41 AM

Yes, because Page Rules can’t cache Workers responses
