Did create a KV and bind it to the worker in the settings on the Web UI ?

Rrob Did create a KV and bind it to the worker in the settings on the Web UI ?

Voids•4/6/24, 4:30 PM

yes

abel•4/6/24, 4:32 PM

in the worker you would have a router

abel•4/6/24, 4:32 PM

using something like hono

abel•4/6/24, 4:33 PM

you create an endpoint that responds with the key or performs a write

abel•4/6/24, 4:33 PM

and then call that endpoint

Voids•4/6/24, 4:35 PM

you lost me after hav a.....

abel•4/6/24, 4:37 PM

a router is basically a big if statement that says, if the request url is a do this action and provide this response, if it’s b do this other action and provide this other response

abel•4/6/24, 4:37 PM

look up the documentation for hono

abel•4/6/24, 4:37 PM

you would need a get endpoint for your read, and a post endpoint for your write

robOP•4/6/24, 4:39 PM

for the sake of simplicity you don't need hono for routes, workers can do routing natively

Voids•4/6/24, 4:43 PM

so then how would I get a worker to do this, IM so confused

Voids•4/6/24, 4:45 PM

I cant get the worker to communicate with the kv

Hey! Sorry if this is the wrong place. I am trying to bind a KV for a specific environment and now the KV doesn't bind correctly in the code. This is what I see in the terminal on startup:

Vars:
...
  - kv-namespaces: [
 {
  "binding": "XYZ",
  "id": "ASDF"
 }
]

Vars:
...
  - kv-namespaces: [
 {
  "binding": "XYZ",
  "id": "ASDF"
 }
]

Before this, I was binding at the top level and this worked as expected where I could access the KV by just doing env.XYZenv.XYZ in code but now it is an array which can't be interacted with. Any help is appreciated! Happy to paste some of the toml and what not if that would be helpful!

kian•4/7/24, 9:01 PM

You've got kv_namespaces = [kv_namespaces = [ below [vars][vars]

kian•4/7/24, 9:01 PM

Move it above

runner5•4/7/24, 9:13 PM

That helped massively! Thank you so much. For anyone else, this was the final result:

[env.dev]
kv_namespaces = [
    { binding = "XYZ", id="ASDF" }
]
vars = { DISCORD_TOKEN = "WER", DISCORD_PUBLIC_KEY = "GFD",  DISCORD_APPLICATION_ID = "ASFD" }

[env.dev]
kv_namespaces = [
    { binding = "XYZ", id="ASDF" }
]
vars = { DISCORD_TOKEN = "WER", DISCORD_PUBLIC_KEY = "GFD",  DISCORD_APPLICATION_ID = "ASFD" }

I had the section labeled as env.dev.varsenv.dev.vars.

Usage is documented here for anyone else looking: https://developers.cloudflare.com/workers/wrangler/environments/#non-inheritable-keys-and-environments

kian•4/8/24, 5:36 PM

It's an annoying intersection between Wrangler's configuration and TOML.

kian•4/8/24, 5:36 PM

Wrangler's configuration really doesn't suit TOML.

kian•4/8/24, 5:37 PM

You can opt-in to wrangler.json with a flag if that's easier

is KV down?

Chaika•4/9/24, 2:32 AM

don't think KV itself is, the api/dash currently seems to be taking a dive though, hopefully status page soon

Gagan Suie•4/9/24, 2:33 AM

well my DO websockets just stopped connecting. so i was wondering if it was realted.

Gagan Suie•4/9/24, 2:33 AM

in dev and prod. works fine in local. :/

Chaika•4/9/24, 2:34 AM

I wouldn't think so. These issues are almost exclusively just api/dash stuff (control plane), internal components like DOs/Workers are rock solid. Haven't had an issue with them even during wider outages like the Nov 2023 one

Gagan Suie•4/9/24, 2:52 AM

now wrangler-action is failing:

Gagan Suie•4/9/24, 2:52 AM

same error on workers and pages

AKStriker98•4/9/24, 7:17 PM

Quick question, is there a way to get the KV database to log changes made in the dashboard? I want to create an audit log in case an account holder accidentally deletes a key and I need to be alerted on it.

Chaika•4/9/24, 8:03 PM

no, from the dash the only events are namespace creation/deletion

Chaika•4/9/24, 8:04 PM

they talked about having something like this here:
https://blog.cloudflare.com/data-anywhere-events-pipelines-durable-execution-workflows

Event Notifications for R2 are just the beginning, though. There are many kinds of events you might want to trigger as a developer — these are just some of the event types we’re planning to support:

Changes (writes) to key-value pairs in your Workers KV namespaces.
Updates to your D1 databases, including changed rows or triggers.

AKStriker98•4/9/24, 8:19 PM

Thanks, missed the note that it’s in beta for R2 but seems like will come out to others later

AAmby would it be possible to support strong consistency on workers kv in the future?

AndyJessop•4/10/24, 7:53 AM

Implementing strong consistency would negate the main benefit of KV, which is low-latency reads, as strong consistency would require a single source of truth. If you need a KV store with strong consistency, you should probably use a Durable Object's Transactional Storage: https://developers.cloudflare.com/durable-objects/api/transactional-storage-api/

zegevlier•4/10/24, 12:13 PM

R2 has strong consistency (mostly, see https://developers.cloudflare.com/r2/reference/consistency/) and supports larger values. That will likely fulfil your usecase

Hurby•4/11/24, 9:37 AM

Is there any way to delete multiple KV pairs at once by just providing the prefix? Let's say I have a "userId" prefix. Do I have to list and then delete KV Paris associated with that prefix? or is there another way?

Hello, I’m Allie!•4/11/24, 10:31 AM

You have to list then delete. There aren't bulk ops APIs atm anyway

Hurby•4/11/24, 11:26 AM

that sounds expensive

Alvee•4/13/24, 4:14 AM

do people use kv as a cache like redis is it fast or slower then redis?

kian•4/13/24, 9:49 AM

Slower

kian•4/13/24, 9:50 AM

KV does not perform like an in-memory datastore, such as Redis. Accessing KV values, even when locally cached, has significantly more latency than reading a value from memory within a Worker script

Kkian Slower

BrianJM•4/13/24, 12:05 PM

What's faster... KV or DO?

kian•4/13/24, 12:08 PM

Usually KV, but it depends.

kian•4/13/24, 12:09 PM

Are you creating the DO in Region A and accessing it in Region A? DO will probably be faster
