I will note too that KV Read TTL is 60 seconds, so even if you were able to write multiple times a second, any readers would see updates a minute later.

TL;DR no

Hi, I’m getting a 429 error when writing to Workers KV via the HTTP API. The docs say the Enterprise plan allows unlimited writes to different keys. I’m on Enterprise and writing to different keys. How can I resolve this?

Are you writing more than 1 time per second per key? That is a hard limit

Thanks for the reply. The RESP API limits requests to 1,200 every five minutes.

I believe you'll need to reach out to your CSM to get this limit relaxed, the part in the docs about it being unlimited on Enterprise is specifically regarding the Workers binding and the REST API is a seperate limit unrelated to KV.

Yes, I’ve switched to using a worker to write to KV, but I see there’s no bulk write support. How can I write to KV concurrently from a worker? My code currently looks like

async function putKeys(env: Env, pairs: Array<Record<string, string>>): Promise<Response> {
  for (const pair of pairs) {
    var lastE = null;

    for (let i = 0; i < retries; i++) {
      try {
        await env.KV_NS.put(pair["key"], pair["value"], {
          metadata: {
            version: "v1",
            timestamp: ((Date.now() / 1000) | 0)
          }
        });
        console.log({"message": `Successful to sync key ${pair["key"]}`});
        break;
      } catch(e) {
        lastE = e;
      }
    }

    if (lastE != null) {
      console.error({"message": `Failed to sync key ${pair["key"]}`, error: lastE});
    }
  }
  console.log({"message": `Successful synced ${pairs.length} pairs`});

  return new Response(null, {});
}

      try {

You probably want to use standard Promise concurrency: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/all

Note that Workers can only make 6 requests at once (that includes KV I believe) so you may need to use something like https://www.npmjs.com/package/p-limit

I’m getting a 403 when listing regional hostnames in a zone, even with DNS read/write permissions. Which additional permission is required?

The code is

const client = new Cloudflare({
  apiToken: CLOUDFLARE_API_TOKEN
});

console.log("List all Regional Services regions available for use by this account.");
for await (const regionListResponse of client.addressing.regionalHostnames.regions.list({
  account_id: ACCOUNT_ID,
})) {
  console.log(regionListResponse);
}

// Got `error: 403 {"result":null,"success":false,"errors":[{"code":1002,"message":"forbidden"}],"messages":[]}`
console.log("List all Regional Hostnames within a zone.");
for await (const regionalHostnameListResponse of client.addressing.regionalHostnames.list({
  zone_id: ZONE_ID
})) {
  console.log(regionalHostnameListResponse);
}

const client = new Cloudflare({

We use KV for application configuration. Most settings rarely change, but for certain data—such as a status change from A to B—workers must see the update immediately.

Our product is paid. We store each user’s overdue status in KV; if they’re overdue, we return an error. After a user pays, the status is updated in central storage and synced to KV, but workers may read a stale overdue value and still return an error. We need a way for workers to read the latest status so users can access the product immediately after payment.

To get the value for a given key, call the get() method of the KV binding on any KV namespace you have bound to your Worker code:

hey, I recently got an email that I surpassed my KV worker limit for the free tier, but when checking the usage on my dashboard they weren't showing any numbers within the metrics, is this a known bug or is there another way to see specific kv worker details?
