if i have that, which should i use for .get and .put, the name or the value?

Nnewbie if i have that, which should i use for .get and .put, the name or the value?

Chaika•10/15/24, 6:25 PM

wishlist_kvwishlist_kv, the name

newbieOP•10/15/24, 6:29 PM

if i did that binding to the worker in the ui, do i need to declare or initialize that kv var before using it? wishlist_kv.get(key)wishlist_kv.get(key) gives me Cannot find name 'wishlist_kv'.Cannot find name 'wishlist_kv'.

Chaika•10/15/24, 6:30 PM

no, show more code though. If you're using module workers/exporting fetch, it's on env and not in global, there's a nice tutorial here: https://developers.cloudflare.com/kv/concepts/kv-bindings/#access-kv-from-workers

Cloudflare Docs

KV bindings | Cloudflare Workers KV

KV bindings allow for communication between a Worker and a KV namespace.

newbieOP•10/15/24, 6:31 PM

code starts with

addEventListener('fetch', event => {
  event.respondWith(handleRequest(event.request));
});

addEventListener('fetch', event => {
  event.respondWith(handleRequest(event.request));
});

newbieOP•10/15/24, 6:31 PM

do i need to add env there?

Chaika•10/15/24, 6:32 PM

no, you're using the old only supported for some products service worker format which should have it as a global var

newbieOP•10/15/24, 6:33 PM

i'll have to read up on migrating to module workers?

Chaika•10/15/24, 6:35 PM

KV should work fine with service workers but module workers are a smarter thing to use for performance/more features/etc reasons, and not that hard if you're just starting to switch: https://developers.cloudflare.com/workers/reference/migrate-to-module-workers/
Otherwise would need to show more of the full code of the service worker

aquarhead•10/18/24, 7:32 PM

Hi, I'm having some trouble expiring keys in KV, I'm using Rust and it's an open source project so you can see I set it here https://github.com/aquarhead/nextgame/blob/master/src/lib.rs#L502 I just enabled logs and according to it I should have set an example object to expire at 19:20 UTC (10min ago)

PutOptionsBuilder { this: Object { obj: JsValue(Object({})) }, put_function: Function { obj: Object { obj: JsValue(Function(put)) } }, name: JsValue("27c43d0052d59077f496"), value: JsValue("{"description":"test game, don't register","players":{},"guests":[],"comments":[]}"), expiration: Some(1729279200), expiration_ttl: None, metadata: None }

PutOptionsBuilder { this: Object { obj: JsValue(Object({})) }, put_function: Function { obj: Object { obj: JsValue(Function(put)) } }, name: JsValue("27c43d0052d59077f496"), value: JsValue("{"description":"test game, don't register","players":{},"guests":[],"comments":[]}"), expiration: Some(1729279200), expiration_ttl: None, metadata: None }

But it's still there even now. Am I missing something apparent here? (This seems to work correctly locally in dev mode)

The GameGame should not exist after 19:20

Constantin•10/19/24, 12:40 PM

hey there.

I'm having two workers - one serving astro and another as a service auth worker
getting this response type when calling the service worker: ProxyStub { name: 'Object', poisoned: false }

Constantin•10/19/24, 12:41 PM

still, the response in the service worker (the user object) comes fine from the KV

Constantin•10/19/24, 1:07 PM

oh it looks i have to stringify when i'm getting the object

Anthony•10/23/24, 8:10 AM

I am having the same issue

danielsundq•10/23/24, 8:18 AM

So is this a known problem at Cloudflare? This causes big issues in our application

Anthony•10/23/24, 8:18 AM

Doesn't seem so, nothing on their status page

danielsundq•10/23/24, 8:18 AM

Yeah saw that too

Anthony•10/23/24, 8:19 AM

but I think generally write latency can be up to a minute
but it usually isn't

danielsundq•10/23/24, 8:49 AM

Yeah it's usually more or less instant

danielsundq•10/23/24, 8:51 AM

Are US or Europe your nearest location? Seems that cloudflare kv storage location is primarily in US and Europe. Maybe the one in Europe is down and rerouted to US, that would explain the issue

danielsundq•10/23/24, 8:51 AM

But would be good to get some input from Cloudflare

We are seeing the same latency spikes. Actually came here because there was no update on the status page.

Jun•10/23/24, 10:16 AM

I'd like to flag this to the KV team - can you let us know whether you're using REST APIs or Binding APIs?

Anthony•10/23/24, 10:35 AM

I am using the binding API. I would also like to add that it's not only latency. For me in some cases the values are never written.

danielsundq•10/23/24, 10:45 AM

Binding API here also. We noticed the problem this morning, about 6 hours ago.

Jun•10/23/24, 10:50 AM

Just to confirm that it doesn't look like isulated case we are seeing this on multiple deployments across regions.

thomasgauvin•10/23/24, 12:32 PM

Thanks everyone, we're looking into this

thomasgauvin•10/23/24, 1:04 PM

@danielsundq @ivogt @Anthony can you share in this thread since when you've been encountering these issues?

ivogt•10/23/24, 1:10 PM

I believe it started after 8:00 UTC yesterday. Speculating on the timing but definately wasn't there the day before. Also we haven't had such problems for months.

ivogt•10/23/24, 1:12 PM

Possibley somethig that happend in the afternoon as we started noticing past 12:00 UTC .

danielsundq•10/23/24, 1:24 PM

We detected the problem this morning, about 06:00 UTC. I don't think it was a problem the day before, because this latency causes big issues with our applications and we didn't notice anything the day before

thomasgauvin•10/23/24, 1:27 PM

Can you all DM me your Workers account id and KV namespace id

I just read: https://blog.cloudflare.com/how-we-built-cloudflare-queues/

Also the part "Workers KV acts as a fast metadata store: our Worker can quickly look up the shard map to perform load balancing across shards"

How can they use KV for that, as KV has a 60 second delay to update after writing? Won't the entire infrastructure have a 60 second delay to understand what the state is and how would the be able to update that state?

I wrote a Cloudflare KV wrapper! I'd love feedback and if you'd add/remove things, including things that are not clear or could be improved (to the library overall or the KV workers bit). I almost did it with the REST API (to avoid having to init it within the

fetch()

fetch()

context and not at the root). But decided the fetch context (only the namespace_idnamespace_id needed + location within that context) might be more worth it than having to force the users to find their

account_id

account_id

, the namespace_idnamespace_id and the Bearer tokenBearer token . Would've preferred a lot more ofc if it was available at the root, but ALAS. Here is the Cloudflare KV-specific docs!

Hey, just a general question, is KV appropriate for creating a authorization layer in my application created using worker?

I think we are okay with the eventual consistency of KV as long as it's under a minute or two.

The KV will be responsible for storing the data and we will create our own logic.

I am pretty much a noob when it comes to AuthZ, so is there a better solution with cloudflare worker? I am okay with a SaaS or an open source solution if available. Thank you.

Ben•10/29/24, 3:22 PM

Any reason why you wouldn’t use d1/serverless database?

Ussssuuaaallllyyyyyy KV stores are meant to be for value caches rather than persistent stores of data.
As in, if you wiped the KV cache, your application would just fill it up again next time around.

(Note: I’m wicked new to the Cloudflare hosted services, but 15 years of other services)

good_for_nothing•10/29/24, 3:38 PM

I hadnt looked into it. The reason KV caught my eyes was because of its low latency and similarities to redis. Thank you for the suggestion

thomasgauvin•10/29/24, 3:42 PM

@good_for_nothing KV is persistent storage, using KV as an authorization layer is definitely a good use case, lots of folks use KV for storing nosql data such as allow/deny lists, auth lists, a/b testing groups, other configuration.

if i have that, which should i use for .get and .put, the name or the value?
