I was just making it clear that there is no limit to how much you can write, besides the per-second per-key limit, but that you don't get unlimited writes included for the base subscription price

wongudikOP•10/26/25, 3:15 PM

my question is why i got this message "message": "KV put() limit exceeded for the day.",, its make my web functionality goes down

boop•10/26/25, 3:15 PM

I'm unsure

wongudikOP•10/26/25, 3:17 PM

is there any customer support that i can contact?

boop•10/26/25, 3:17 PM

It requires a paid plan, otherwise you could wait for someone that can look into your account to see this Discord chat. No guarantee though

boop•10/26/25, 3:17 PM

You could try redeploying your application and see if that fixes things?

wongudikOP•10/26/25, 3:19 PM

my current plan is paid plan brother.

looks like cloudflare caching my free plan. my problem fix when i downgrade plan. when i downgrade plan, all paid plan feature come up. may be its triggering force cache.

hi guys, for some reason I can't delete my KV namespace

Tony Leung•10/27/25, 8:06 AM

it's showing this error:

remove namespace: 'namespace has associated scripts: pages-worker--1260571-production'

remove namespace: 'namespace has associated scripts: pages-worker--1260571-production'

Tony Leung•10/27/25, 8:06 AM

but that deployment has been deleted a long time ago

vmg•10/28/25, 5:45 PM

is it possible to update a key from playwright tests?

vmg•10/28/25, 5:46 PM

I have a worker running locally and want to create a test session for a user

thomasgauvin•10/30/25, 9:06 AM

If you want to access Workers KV from an external service, you can use the REST API https://developers.cloudflare.com/api/resources/kv/

If you are running Workers locally, you can also use remote bindings in your wrangler configuration https://developers.cloudflare.com/changelog/2025-09-16-remote-bindings-ga/

You can now connect to R2 buckets, D1 databases, and other resources running on Cloudflare, while running your Worker's code locally, on your own machine.

Paul•10/31/25, 11:37 PM

Just wanted to confirm there is no Change Data Capture capability with KV, right? I was hoping I could send CRUD events to a Queue so I can trigger other behaviors in response to the KV state changes. I know I can do this in a Worker, but was looking for a storage level solution, like DynamoDB Streams so each Worker interfacing with the KV don't need to handle this concern. Is this on this roadmap and if not can I request it

Property cursor does not exist on type 'KVNamespaceListResult<unknown, string>'.

Are there more KV upper tiers on the business plan? I'm storing a lot of per-user configuration data in KV (both read and write), which means occasionally getting cold reads since its locally cached but can be modified in other places. Response times in APAC and OC (Australia especially) are rough. I had some friends in Japan and Australia hit a benchmarking endpoint (i know timing across I/O isn't the most precise, but it seems to be relatively accurate given the endpoint resolution time)

300-400ms reads and 1500ms writes aren't exactly the end of the world, especially with waitUntil, but it is frustrating for some users. Thought I'd ask before looking into migrating to per-user durable objects

PhoenixSpace•11/6/25, 9:13 PM

Yeah the eventual consistency isn’t an issue. The problem is more per user data could be updated overnight, and when they check during the day, it hits a cold read

PhoenixSpace•11/6/25, 9:13 PM

Read your own write is extraordinarily performant. It’s just cold reads

1984 Ford Laser•11/6/25, 9:19 PM

Only way to avoid cold reads is to regularly read I guess

DOs would be a good use case as long as the instances are spawning close to users (I've had this issue recently where I had DOs spawn on the other side of Australia to me, was seeing 100s of ms extra request time)

thipperz•11/7/25, 6:29 PM

Hi everyone, I'm using KV to cache some heavy db calls in my app, I have something like

const cached = await KV.get(key, { type: 'json', cacheTtl: 1800 })
if (cached) return cached

await KV.put(key, JSON.stringify(value), { expirationTtl: 1800 })

const cached = await KV.get(key, { type: 'json', cacheTtl: 1800 })
if (cached) return cached

await KV.put(key, JSON.stringify(value), { expirationTtl: 1800 })

Even with both

cacheTtl

cacheTtl

and

expirationTtl

expirationTtl

set to 1800 (30 min), the D1 analytics show hundreds of reads over 48 hours, even though the value rarely changes and should be served from cache most of the time. For example I expected around 96 calls but i'm getting like ~500.

I think I might be misunderstanding something about how KV works, is there some gotchas I must be aware of? Thanks

thomasgauvin•11/10/25, 5:39 PM

KV does store the key value pairs for as long as the expiration ttl, and it should return the values so we'd probably need more of your code to understand why you're going to D1 instead of KV (because it should be in KV)

thipperz•11/12/25, 2:48 AM

Got it, I'm testing to see if the issue isn't somewhere else before I ask for further help

thipperz•11/12/25, 2:52 AM

One other thing: i tried to delete a KV Namespace from the Dashboard, but get a error message saying

remove namespace: 'namespace has associated scripts: pages-worker--2406846-production

remove namespace: 'namespace has associated scripts: pages-worker--2406846-production

However I don't have any pages project anymore (I used to have one before I moved to open-next with Workers instead). I checked and none of my current Workers use that namespace anymore.

chesha1•11/17/25, 3:08 AM

Bulk update can only be used with the REST API or the Wrangler CLI for now, which means I need to create an API key. I’m wondering if this can be used with Workers KV bindings in the future, as that would be more convenient.

ddsgadget•11/18/25, 11:45 AM

Can I assume KV is done again? All my workers with KV are failing with KV errors, and can't log into the Cloudflare Dashboard either, which is exactly what happened last time. I believe the dashboard is powered by some KV in the background.

AZipr•11/18/25, 12:36 PM

Likewise. It resumes for a moment then disappears

This was related to the outage on November 18, here is the report: https://blog.cloudflare.com/18-november-2025-outage/

Cloudflare outage on November 18, 2025

Cloudflare suffered a service outage on November 18, 2025. The outage was triggered by a bug in generation logic for a Bot Management feature file causing many Cloudflare services to be affected.

morpig•11/21/25, 10:42 AM

wondering if anyone here also have p99 >500ms for reads in same region?

Hello, I’m Allie!•11/21/25, 8:28 PM

What is the “external resource” in this case? Do you need an HTTP API? Do you want filesystem access?

Hard@Work•11/21/25, 9:50 PM

You could expose a Worker that mimics the API you want?

I found a similar (unanswered) question from 2024, but I'll try anyway: I need to implement a counter on Workers using KV, but it has a 1 write per second key limit (https://developers.cloudflare.com/kv/platform/limits/). Is the limit really enforced? Is there any workaround?

HHard@Work What exactly are you trying to do?

Hard@Work•12/9/25, 7:50 PM

You could use a DO, which aggregates counts, and then periodically pushes to KV?

khazit•12/9/25, 7:52 PM

I could, but KV is simpler as I already use it for other things on the same worker

khazit•12/9/25, 7:53 PM

So it is enforced and there is no workaround?

Kkhazit So it is enforced and there is no workaround?

Hard@Work•12/9/25, 7:53 PM

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

khazit•12/9/25, 7:54 PM

Ok thanks

mackong•12/15/25, 11:42 AM

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?

thomasgauvin•12/15/25, 6:55 PM

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

I’ve only used 2,000 write operations in KV, in a month. While the monthly limit is 1 million.
