The initial request seemed focused on reducing Workers KV reads, which could be done with rate limiting applied at the per-user level

SajidBanday•3/10/25, 11:46 AM

Do the KV limits mentioned in Cloudflare's documentation apply per account or per KV namespace, specifically for reads and writes?

Isaac McFadyen•3/10/25, 1:52 PM

It varies. The read/write counts for free plan are per account, the others are fairly self-explanatory (they have the denominator listed beside them, i.e. the writes per key or the storage per account)

Is there a way to turn off replication from one of the central stores, and only keep things in the EU? (GDPR compliance)

zecanard•3/20/25, 7:36 AM

I'm having an issue with the KV cache. Up until recently (sometime after mid-February?), I was able to use a very long TTL when retrieving values from the KV. Then, whenever I made an update, my Workers would use a TTL of 60 to retrieve the new entry, as described by the documentation:

The effective cacheTtl of an already cached item can be reduced by getting it again with a lower cacheTtl. For example, if you did NAMESPACE.get(key, {cacheTtl: 86400}) but later realized that caching for 24 hours was too long, you could NAMESPACE.get(key) and it would check for newer data to respect the provided cacheTtl, which defaults to 60 seconds.

Now however, even with a TTL of 60,

get

get

keeps returning the old entries, which have a very long TTL.

What’s odd is that if I repeatedly refresh the KV Pairs page on the Dashboard, it will randomly show me either the new values, or the old ones.

Any help would be appreciated. Thank you.

I was trying to connect my Netlify Edge Function to any KV store and was having trouble finding one that would work (I've even written my own KV JS library in the past); so ended up creating a thin wrapper around Cloudflare's REST API that worked great!

const baseUrl = `https://api.cloudflare.com/client/v4/accounts/${CLOUDFLARE_ACCOUNT}/storage/kv/namespaces/${CLOUDFLARE_NAMESPACE}`;
const headers = { ... };  // Auth stuff

class CloudflareRest {
  EXPIRES = true;

  async get(key) {
    const res = await fetch(`${baseUrl}/values/${key}`, { headers });
    if (res.status === 404) return null; // It does not exist
    const data = await (res.headers.get("content-type").includes("json")
      ? res.json()
      : res.text());
    if (typeof data !== "string") return null;
    return JSON.parse(data);
  }

  async set(key, body, { expires }) {
    const expiration = expires ? `expiration_ttl=${expires}&` : "";
    await fetch(`${baseUrl}/values/${key}?${expiration}`, {
      method: "PUT",
      headers,
      body: JSON.stringify(body),
    });
    return key;
  }

  async keys(prefix) {
    const res = await fetch(`${baseUrl}/keys`, { headers });
    const data = await res.json();
    return data.result
      .map((it) => it.name)
      .filter((key) => key.startsWith(prefix));
  }

  async *iterate(prefix) {
    // ...
  }
}

const store = kv(CloudflareRest);
// console.log(await store.get("hello"));
// console.log(await store.set("hello", { world: "spins" }));
// console.log(await store.get("hello"));

const baseUrl = `https://api.cloudflare.com/client/v4/accounts/${CLOUDFLARE_ACCOUNT}/storage/kv/namespaces/${CLOUDFLARE_NAMESPACE}`;
const headers = { ... };  // Auth stuff

class CloudflareRest {
  EXPIRES = true;

  async get(key) {
    const res = await fetch(`${baseUrl}/values/${key}`, { headers });
    if (res.status === 404) return null; // It does not exist
    const data = await (res.headers.get("content-type").includes("json")
      ? res.json()
      : res.text());
    if (typeof data !== "string") return null;
    return JSON.parse(data);
  }

  async set(key, body, { expires }) {
    const expiration = expires ? `expiration_ttl=${expires}&` : "";
    await fetch(`${baseUrl}/values/${key}?${expiration}`, {
      method: "PUT",
      headers,
      body: JSON.stringify(body),
    });
    return key;
  }

  async keys(prefix) {
    const res = await fetch(`${baseUrl}/keys`, { headers });
    const data = await res.json();
    return data.result
      .map((it) => it.name)
      .filter((key) => key.startsWith(prefix));
  }

  async *iterate(prefix) {
    // ...
  }
}

const store = kv(CloudflareRest);
// console.log(await store.get("hello"));
// console.log(await store.set("hello", { world: "spins" }));
// console.log(await store.get("hello"));

Just keep in mind that the API has a limit of 1200 requests per 5 minute period

ajgeiss0702•3/22/25, 4:35 AM

anyone else seeing weird issues with kv?

ajgeiss0702•3/22/25, 4:35 AM

a bunch of my keys are randomly acting like they don't exist for a while, then show fine for a few minutes, then go back to acting like they don't exist for a while

ajgeiss0702•3/22/25, 4:50 AM

like these keys definitely exist

ajgeiss0702•3/22/25, 4:50 AM

yet they return null when I try to fetch them from workers

ajgeiss0702•3/22/25, 4:52 AM

even in the dashboard, they aren't always there for some reason. They show up most of the time in the dashboard, but not always

Can you send the KV namespace ID please? (it's fine/safe to share publicly) Me or someone else can try and escalate if we have the chance.

The fact that the dashboard is also sometimes not returning the keys makes me think it's not your code, so I'll go ahead and see if I can raise this.

ajgeiss0702•3/22/25, 4:59 AM

the issue is also occurring across two different workers if that helps
