No one can ever read another persons resources without explicitly being allowed by that person

So, no. No one can read your KV unless you explicitly create like an API for them to do so

It takes up to 60 seconds for new values to be reflected

By #1 the caveat is that KV values can be viewed on the dashboard, but as Walshy said, they'd need access to your Cloudflare account to do that.

as long as it's not publicly available like static websites, that's all good yes thanks

is this too much for KV read ops?
data is a json 30KB

😈 Donkey 💫•11/28/24, 1:05 PM

testing after read: https://blog.cloudflare.com/faster-workers-kv/

this is string value of 1KB. That's a lots

11984 Ford Laser I know it isn't many reads, but man when KV is doing hot only reads it is *fast*

1984 Ford Laser•11/28/24, 1:11 PM

Okay cool so not localised, absolutely abnormal

😈 Donkey 💫•11/28/24, 1:31 PM

I admit that more a half are cold reads, but compare to … CDN cache read? That’s too much for KV

1984 Ford Laser•11/28/24, 1:31 PM

Even my cold reads have never been higher than 300 or so

how do i set the expiry "since modified"? (for a key using put)

or after a certain amount of time has passed since the key was last modified.

https://developers.cloudflare.com/kv/api/write-key-value-pairs/

all i see is expiry at a fixed time since epoch and expiry in seconds from now

JJacob Correct, every time you write to the key and include the `expirationTtl`, it wil...

pat me•12/1/24, 9:28 AM

ohhhhhh i modify the ttl at write time dam, that's a simple way to handle it lol

It does not, no.

All data will stay in KV unless the namespace is deleted or the data is deleted by you.

IIsaac McFadyen It does not, no.

Chaika•12/13/24, 3:55 AM

no outage, https://www.cloudflarestatus.com/. I don't see any issue uploading keys either. Did it work on retry? Very rarely I do see PUTs fail in my own stuff, I see one in last 12 hours w/ 7k puts, sane retry policies are always helpful tho

Is there any way to duplicate a KV database so I can take my production data and bring it into a separate environment I can safely use for testing?

Keavon•12/14/24, 6:55 AM

Or even to clone my production data down to a local copy?

thomasgauvin•12/16/24, 5:39 PM

It's not possible to do this at the moment, the recommendation is to use the REST API or Workers directly in order to migrate the data.

DaniFoldi•12/25/24, 5:09 PM

subrequests have their own limit, so the solution you described would work

DaniFoldi•12/26/24, 5:20 PM

yup, you have to add the worker itself as a binding, and then it's the same as invoking another worker

DaniFoldi•12/26/24, 5:20 PM

there's a depth limit, so you can't recurse indefinitely, but I've never hit that accidentally

DaniFoldi•12/26/24, 8:51 PM

yup, RPC (if that's what you mean by function) is also counted as a separate invocation, so fresh 1k

Adam•12/31/24, 12:32 PM

Howdy! I noticed a werid think in the Cloudflare ui for kv pairs. I can see a key in my kv when I page through but when I search for that key it doesn't show. I copy and paste the key from the list (4f1b9e271b72b589). some of the keys work but others don't. Is it possible the key has some kind of hidden character in it?

Adam•12/31/24, 12:37 PM

I just checked and the key is there if I use wrangler!?

maguayo•1/2/25, 8:35 AM

Are KV updates instant? For what I read. I think it take sup to 60 seconds to propagate to other regions, but in the user's region, the Update & Read should be consistent and almost instant?

Isaac McFadyen•1/4/25, 2:48 AM

Consistent in the same datacenter. But there are 340+ datacenters across the globe, and sometimes a user can flip-flop between two (rare but happens) or might switch to a new one on cellular vs wifi, so don't rely on the consistency at all really.
