Hello, I’m Allie!•3/30/24, 10:34 AM

You build a Worker to send requests through?

H

Hello, I’m Allie!•3/30/24, 10:34 AM

Other than that, no. The Cloudflare API is generally pretty slow, when compared with Workers bindings

DaniFoldi•4/1/24, 8:40 AM

bulk reads unfortunately aren't supported by the binding, and not even by the api, since individual values could be up to 25MB in size - if your data is small (eg. fits in key + metadata), you can use

list

to get up to 1k keys at a time

Yeah metadata is unfortunately 1 or 2kb, can’t remember exactly, so too large, you can either chunk the files or batch them into a single larger kv value

Does KV have read/write units? I.e. If I write 10MB into a value, is it the same price as writing 10KB?

Isaac McFadyen•4/1/24, 2:51 PM

Yes, same price. All writes are billed as the same amount.

Isaac McFadyen•4/1/24, 2:52 PM

KV has a limit of 25MB per value so that's the limit there, but anything below the limit is billed the same.

Durable objects is the only product that bills by units instead of just read or write

DaniFoldi•4/2/24, 7:34 AM

For values that are cached, retrievals should be much faster. For new reads, they come from one of the core locations. See https://developers.cloudflare.com/kv/reference/how-kv-works/ for how it works

Hi, I am having issues assessing my KV namespace. Also I created my worker on vscode but I cannot see it on my cloudflare web account. Could this be why there is a discrepancy in assessing my namespace and if it is or whyever this is happening, could I get assistance from someone here please?

No, you can only use KV namespaces from the same account

Chaika•4/4/24, 1:42 AM

KV has two central stores, one in US, one in EU, and then caches at each location for the CacheTTL (which is min/default 60s), so Indonesia is a fair bit away but shouldn't be that high, and should be relatively low after it is cached

well YokoWasis's specific issue is his ISP was routing him from Indonesia to Europe for a bit, but eventually straightened out, so you shouldn't see as bad latency like he did, but yea it would be nice if there was a central store over there.

Are you using a framework or migrating from another platform?

const kvNamespaceId = '97';
const kvNamespace = KVNamespace(kvNamespaceId);

const kvNamespaceId = '97';
const kvNamespace = KVNamespace(kvNamespaceId);

const kvNamespaceId = '97';
const kvNamespace = KVNamespace(kvNamespaceId);

const kvNamespaceId = '97';
const kvNamespace = KVNamespace(kvNamespaceId);

This isn't a standard way to access a KV binding
