Okay,

I want to make a counter which counts the no. of requests hitting my worker. Is there a better option for this value fetch ??

I was thinking of kv earlier but it is billable and expensive for a simple counter property as it requires write action in every request.

Is there a better way for this value to be accessible in the worker itself?

KV is not a good fit for that anyway because it's eventually consistent. See my message here: https://canary.discord.com/channels/595317990191398933/874727019479437372/1411943337698529381

I'd recommend Durable Objects or D1, both of which will likely be cheaper.

SbOP•9/9/25, 2:03 PM

I saw firebase real-time as one of the good fit in this case, would you recommend using realtime in place of kv in this situation?

Isaac McFadyen•9/9/25, 2:11 PM

Firebase pricing is quite high, so depending on Worker traffic you'd quickly hit the limit of a free tier and be charged.

Isaac McFadyen•9/9/25, 2:12 PM

It's also not very fast, meaning you'd need to use waitUntil()waitUntil() to avoid delaying the request.

Isaac McFadyen•9/9/25, 3:37 PM

If I'm understanding what you're asking, the worker will always be invoked. In order to 'stop' the Worker you'd need to unbind it from the actual domain/zone, because once a request reaches far enough for you to check if you're over the limit it would be billed.

SbOP•9/9/25, 5:13 PM

So, what i have configured is.

Instead of binding the worker to the zone via zone property, I added a route to the domain in the worker configuration.

And when I hit (may be a X number) of requests, I would like to stop serving on that route or remove those routes.

What I remember from the free tier is, it stops automatically after 100k and I want to set similar kinda concept in the paid tier also.

I am using pages to host static files mainly (as any incorrect automatically triggers 404) and using worker for (some static assets), dynamic pages, and api endpoints.

When the client set limit exceeds, I don't want the workers to be invoked on those routes to save clients cost. (Stop api.xyz.com)

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

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

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/

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

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

Tthipperz Hi everyone, I'm using KV to cache some heavy db calls in my app, I have somethi...

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)
