Still receiving the message "Daily request limit exceeded for Cloudflare Workers" for a "1000 put op

Still receiving the message "Daily request limit exceeded for Cloudflare Workers" for a "1000 put operations" which is in fact of 226 right now!
More than a week has passed, shouldn't we have more information?

Hello every one ! Have anyone know how to rename the KV Namespace?

I remember that it could be renamed in the past but now it seems not to work anymore

Thanks for bringing it up again. This is our top priority fix at the moment. A query that is being made to alert on free quotas is misreporting quotas, so we’re fixing that. I will keep this message thread updated. Note that the query resets every day so you may not encounter this all the time

I'd have to look at how I've done it before but my knee jerk (from my phone) reaction without looking is probably timestamp in the Metadata, maybe something like this

async function setKVValueWithTimestamp(key, value, cacheTtl) {
  const timestamp = Date.now();
  const data = JSON.stringify({ value, timestamp });
  await KV_NAMESPACE.put(key, data, { expirationTtl: cacheTtl });
}

In case you missed it — here's the details on the latest Workers KV performance improvements that just shipped! https://blog.cloudflare.com/faster-workers-kv/ @Workers KV

The Cloudflare Blog

We made Workers KV up to 3x faster — here’s the data

Today, we’re announcing up to 3x faster KV hot reads, with all KV operations faster by up to 20ms. And we want to pull back the curtain and show you how we did it.

AZipr•9/26/24, 3:16 PM

In the kv docs /getting-started

I can't get this command to work:

npx wrangler kv key put --binding=<BINDING_NAME> "<KEY>" "<VALUE>"

just trying to follow the kv-tutorial

I used kv_binding_name - trying to follow the docs.

Though the docs say: name it BINDING_NAME - the very next step shows a create command with kv_binding_name

✘ [ERROR] A namespace with binding name "kv_binding_name" was not found in the configured "kv_namespaces".

Thanks for flagging! let me verify

thomasgauvin•9/30/24, 2:27 PM

@kindaraffy yes, expiration is supported in the REST API, we'll be fix that in docs

You can specify expiration or expirationTtl as a query param

So I can tell the users: https://api.cloudflare.com/client/v4
/accounts/{account_id}/storage/kv/namespaces/{namespace_id}/values/{key_name}?expiration=<secondsSinceEpoch>

or https://api.cloudflare.com/client/v4
/accounts/{account_id}/storage/kv/namespaces/{namespace_id}/values/{key_name}?expirationTtl=<secondsFromNow>

carlos-alberto•10/1/24, 3:22 PM

Hey! Are there documented (or undocumented) rate limits on number of writes to different KV keys from a worker (on the paid plan)? We are seeing 429s when we try to write a few thousand keys within a few seconds.

thomasgauvin•10/1/24, 3:29 PM

KV has 1 write per second per key limit from the binding https://developers.cloudflare.com/kv/platform/limits/ and the APIs have global rate limits https://developers.cloudflare.com/fundamentals/api/reference/limits/#:~:text=The%20global%20rate%20limit%20for,receiving%20a%20HTTP%20429%20response.

carlos-alberto•10/1/24, 3:31 PM

Do the api rate limits apply to calls made from a worker binding?

carlos-alberto•10/1/24, 3:32 PM

We are writing to different keys, so the 1 per second should not apply

thomasgauvin•10/1/24, 3:41 PM

ItsWendell•10/1/24, 4:41 PM

Related to the new upcoming cache purging changes, couldn't these also apply to KV?

https://blog.cloudflare.com/instant-purge/

Is it generally possible to purge a specific KV key? I think if a KV value is locally cached, and you update this it could in theory especially with the new purging system 'instantly' purge all regional KV caches right? Think this could bring quite some benefits to keep KV reads latency.

E.g. I need super quick access to a 'configuration' stored in KV, this 'configuration' is updated at most a couple of times a day. If we can keep this in the cache until this value is updated or deleted, it would speed up calls to KV a lot. Currently it's documented that KV updates do not purge KV caches, in this case it would be great if it did!

thomasgauvin•10/2/24, 7:37 PM

Thanks for the feedback @ItsWendell, like you mentioned, KV doesn't have cache purges but it's something we're keeping our eyes on

Isaac McFadyen•10/6/24, 2:49 AM

The "inconsistency" of KV would just mean that an update might take 60 seconds to propogate globally. If you're OK with 60-second delays when adding or removing permissions then KV would still be suitable, but if not then KV isn't for you.

thousandmiles•10/6/24, 2:52 AM

yes, I did assume permissions are usually crucial for production environment best with zero latency and 100% consistency.
what about D1? that said, I actually stick to D1 for auth data for my development project... simply because D1 offers more free allowances.

Isaac McFadyen•10/6/24, 2:58 AM

D1 is single-region currently, so while you'd get consistency there you're definitely not going to get zero latency.

Isaac McFadyen•10/6/24, 2:59 AM

In general there's no such thing as zero-latency, 100% consistency - all databases are just trading one for the other, some fully (i.e. KV prioritizes speed, D1 prioritizes consistency) and some partially (i.e. in etcd you can choose to read possibly-stale values or consistent values and your app can make that choice itself)

Ashish Rawat•10/6/24, 6:21 PM

Permissions doesn't change often. Firebase auth token cache auth tokens upto 1 hr by default. 60sec doesn't seems to be problem.

Isaac McFadyen•10/6/24, 6:38 PM

Yeah IMO 60 seconds is perfectly OK for permission use-cases. Even if you need to revoke permissions from a user quickly because of an issue, 60 seconds is very quick and won't give them much time to do anything dangerous.

Isaac McFadyen•10/6/24, 6:39 PM

You can also implement it as a tiered system: for most permission requests you can check KV, but then if there's something extremely sensitive (like billing details or a purchase or something) you can go back to a central DB that is consistent.

Wrangler can emulate KV in a Worker for you

jrydberg•10/6/24, 7:49 PM

I'm running a worker locally (

wrangler dev

wrangler dev

) and trying to access some KV keys I've set using wrangler kv key put ... --local <key> <value>wrangler kv key put ... --local <key> <value> but my <kvnamespace>.get in my worker always returns null. I tried listing them from the worker too, and there's no keys at all. Listing them with "kv key list --local" tells me they are there. I can also read them with kv key getkv key get. Any suggestions on where I should start to dig to figure it out?
