GGagan Suie is KV down? API Request Failed: GET

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 SuieOP•4/9/24, 2:33 AM

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

Gagan SuieOP•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 SuieOP•4/9/24, 2:52 AM

now wrangler-action is failing:

Gagan SuieOP•4/9/24, 2:52 AM

same error on workers and pages

Chaika•4/9/24, 2:52 AM

kv api still dead: https://www.cloudflarestatus.com/incidents/w5c2r6mqjshl

ah i see it on status page now

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

kian•4/13/24, 12:09 PM

Accessing it globally? KV will be faster due to local caching + central stores in 2 regions

bun•4/13/24, 1:02 PM

kv is very expensive

bun•4/13/24, 1:02 PM

for no reason

juanferreras•4/16/24, 10:15 PM

is using KV metadata simply incompatible with the dashboard? I'm tempted to use metadata for list()list() calls to be self-sufficient, but I worry we'll create a new entry or update an existing one using the Cloudflare Dashboard and we'll have metadata !== value

(or, are there any easy ways to view/edit metadata within the dashboard?)

James•4/16/24, 11:09 PM

There's no way to view/edit KV metadata within the dashboard today, nope. I'm not entirely sure honestly what happens if you edit a key's value in the dashboard that already has metadata - that's probably worth testing.

BBrianJM What's faster... KV or DO?

Unsmart•4/16/24, 11:27 PM

I'm a bit late to the party but I would personally recommend you always use DO over KV personally. Especially when you can create a DO per user as DOs are faster than KV when close to the user. Only time I use KV is when I am too lazy to bring up a wrangler project and just make a small worker via dash lol.

Unsmart•4/16/24, 11:28 PM

Only time KV is really more useful than DOs are when you have larger values but then I would just recommend R2

森@VerseLink (RW)•4/17/24, 2:48 AM

would you say DO or KV would be better for reference tokens? (so that we can check up to see if a token is valid or not)

W7T2A•4/17/24, 12:49 PM

Is there any option for exporting all data as a backup / or a builtin backup functionality for a kv store? Or is the only way to do this by creating a script via API (for now)

you can get storage by namespace analytics via api: https://developers.cloudflare.com/api/operations/workers-kv-stored-data-analytics-query-stored-data-analytics

can't do requests by namespace though

sdan•4/19/24, 3:12 AM

anyone know if its possible to use KV within a nextjs app or would i need to make a worker to interface with KV and expose an api from that worker. wondering if the Binding works for nextjs

Rubi•4/19/24, 3:37 AM

should I use KV or Durable Object for a quick session check?

Rubi•4/19/24, 5:57 AM

let me stay on D1

RRubi should I use KV or Durable Object for a quick session check?

bun•4/19/24, 9:39 AM

DO's are cheaper and faster (for a single region)

Bbun DO's are cheaper and faster (for a single region)

bun•4/19/24, 9:39 AM

but ye, D1 is fine, i have it on d1 as well

Bbun DO's are cheaper and faster (for a single region)

Rubi•4/19/24, 9:54 AM

do ia faster than KV?

RRubi do ia faster than KV?

Hello, I’m Allie!•4/19/24, 9:55 AM

If the DO is near you, then yes

Rubi•4/19/24, 9:56 AM

alright, gonna using DO

RRubi alright, gonna using DO

bun•4/19/24, 10:12 AM

offtopic but your pfp goes insanely hard

mau•4/20/24, 12:30 PM

I am implementing cache purging function but hitting a roadblock

for example

http://localhost:8787/api/addons?where[id][equals]=66221339a9cb9c462a245943 caches data from http://localhost:3000/api/addons?where[id][equals]=66221339a9cb9c462a245943

and i am using cloudflare kv for caching. I am generating the kv key using below hash function

export async function getHashString(input) {
  const encoder = new TextEncoder();
  const data = encoder.encode(input);
  const hashBuffer = await crypto.subtle.digest('SHA-256', data);
  return bufferToHex(hashBuffer);
}

function bufferToHex(buffer) {
  const view = new DataView(buffer);
  let hex = '';
  for (let i = 0; i < view.byteLength; i += 1) {
    const byte = view.getUint8(i).toString(16);
    hex += byte.padStart(2, '0');
  }
  return hex;
}

export async function getHashString(input) {
  const encoder = new TextEncoder();
  const data = encoder.encode(input);
  const hashBuffer = await crypto.subtle.digest('SHA-256', data);
  return bufferToHex(hashBuffer);
}

function bufferToHex(buffer) {
  const view = new DataView(buffer);
  let hex = '';
  for (let i = 0; i < view.byteLength; i += 1) {
    const byte = view.getUint8(i).toString(16);
    hex += byte.padStart(2, '0');
  }
  return hex;
}

Can someone suggest a method for clearing the cache in the scenario described? I know how to handle cache invalidation for individual items as it's straightforward, but I'm unsure how to effectively clear the cache for queries that involve collection filtering, such as those with multiple conditions. What strategies could work for this more complex case?

export async function getHashString(input) { const encoder = new TextEncoder(); const data = encoder.encode(input); const hashBuffer = await crypto.subtle.digest('SHA-256', data); return bufferToHex(hashBuffer); } function bufferToHex(buffer) { const view = new DataView(buffer); let hex = ''; for (let i = 0; i < view.byteLength; i += 1) { const byte = view.getUint8(i).toString(16); hex += byte.padStart(2, '0'); } return hex; }
