using the cloudflare TS API Library, I can successfully update a KV value using the client.kv.namespaces.bulk.updateclient.kv.namespaces.bulk.update method, but when I try to use client.kv.namespaces.values.updateclient.kv.namespaces.values.update it always returns a

null

null

value rather than any kind of error message. I feel like I'm going crazy

I am setting up kv for sesions management. But I cam acros this repo https://github.com/bruceharrison1984/kv-d1-benchmark
which suggests that d1 performance is similar to kv. Is that the case?
I would like to store and query other info about the session if I can. if d1 gives me the same performance, i'd rather use that.

Can someone please help me understand what "Operations/Worker invocation" means?

Horsie•1/9/25, 12:31 PM

Can I access my kv from a worker only 1000 times per day? That seems unlikely

Walshy•1/9/25, 1:52 PM

Worker invocation means each time the Worker is invoked. So if you're using HTTP, every HTTP request received. Crons, every cron schedule fired, etc.

Every time the Worker is ran, you can do 1000 operations.

Benchmark is old, KV is faster - https://blog.cloudflare.com/faster-workers-kv/

but I'd recommend just using the right tool for the job over the one which is a tad faster. what the right one is, that's for you to decide.

Perhaps it will be to spell it out over there. '/' can be misinterpreted as 'or'.

reor•1/10/25, 11:32 AM

I'm unable to delete a KV namespace, even though:

All associated Worker scripts have been deleted from deployment.
The namespace still shows associations with the respective scripts, even after attempting to delete it during a brief period when the KV storage was empty (this was temporary due to the situation below).

Situation:

I attempted to remove all KV pairs from the namespace directly using the Cloudflare API, but the KV pairs reappeared after a few hours.

What should i do? I suspects an in-depth technical support is required. Thank you.

Isaac McFadyen•1/13/25, 6:59 PM

Different product.

Isaac McFadyen•1/13/25, 6:59 PM

KV is Cloudflare's own product and so has it's own API methods/infrastructure/backend.

Isaac McFadyen•1/13/25, 6:59 PM

The exact backend powering KV isn't public though.

It is not opensource I guess?

King Kazu•1/21/25, 6:15 PM

I really want to use kv, but the cold read latency is kinda killing me. For context, I am starting an API gateway service for API provides (similar to something like an API marketplace), and I use KV to store config details about the API and the end user. KV is god tier when I load test with tons of reqs / sec, but for more realistic scenarios of bursted requests at a smaller scale, I am getting P90 of ~300ms which is just not feasible. Would love to stay on Cloudflare services such as D1, but Upstash Redis seems like a good fix. Any thoughts?

How often does that data change? The ttl property on get requests may help.

EElliot Hesp How often does that data change? The ttl property on get requests may help.

Not often but only thing is data changes should be reflected quickly (e.x certain api key gets banned, don’t want to wait super long)

Hello, only based on object TTL; i.e. after you update a value, the safest is to purge after max TTL defined for your objects + some small buffer.

Following is my Question and Answer(given by ChatGPT)
Please confirm / update the Answer given by ChatGPT. Thanks.

QUESTION :
In the following Cloudflare Worker Code to List by Prefix .. how will the billing happen ? .. billing only for the Keys which are read and correspond to prefix or billing for complete scan of the KV namespace ?

export default {
async fetch(request, env, ctx) {
const value = await env.NAMESPACE.list({ prefix: "user:1:" });
return new Response(value.keys);
},
};

ANSWER by CHATGPT :
In Cloudflare Workers, billing for KV operations depends on the specific API calls and the data retrieved. Here's how the billing works for your provided code:

KV List API Billing

The
```
KV.list()
```
```
KV.list()
```
operation is billed based on the number of keys returned that match the
```
prefix
```
```
prefix
```
filter, not the total number of keys in the namespace.
The filtering by
```
prefix
```
```
prefix
```
is handled internally by Cloudflare, so the operation scans only the relevant part of the namespace that matches the specified
```
prefix
```
```
prefix
```
.

### 2. Breakdown of Costs

List Operation: Each call to
```
list()
```
```
list()
```
counts as a single read operation, regardless of the number of keys returned.
Key Retrieval: You are billed for each key returned in the
value.keys
value.keys
array. If the
```
list()
```
```
list()
```
operation retrieves 10 keys, it will count as 10 read operations.

### 3. Example Billing Scenario

Assume

NAMESPACE.list({ prefix: "user:1:" })

NAMESPACE.list({ prefix: "user:1:" })

returns 50 keys.

You are billed for:
- 1 list operation (base cost for calling the
```
list()
```
```
list()
```
  method).
- 50 read operations (one for each key returned in the result).

### 4. What Is NOT Charged

You are not billed for scanning or evaluating keys that do not match the
```
prefix
```
```
prefix
```
. The filtering happens on Cloudflare's side, and only matching keys are returned and billed.

This means you are billed based on the keys matching your prefix and retrieved by the

list()

list()

operation, not for scanning the entire namespace.

Hello, does the expiration set at the key creation persists if I put on the key without specifying expiration?

Mathis @ blaxel.ai•1/23/25, 10:14 PM

E.g in this code:

await env.NAMESPACE.put(key, value, {
  expiration: secondsSinceEpoch,
});

await env.NAMESPACE.put(key, value);

await env.NAMESPACE.put(key, value, {
  expiration: secondsSinceEpoch,
});

await env.NAMESPACE.put(key, value);

MMathis @ blaxel.ai Hello, does the expiration set at the key creation persists if I put on the key ...

se•1/24/25, 2:42 PM

No, it does not inherit the expiration settings of the previous overwritten object.
