XHi Cloudflare team,
I'm experiencing an issue with KV read operations and would like some clarification. In my project hosted on Cloudflare Pages, we have around 500k total visits, and within those, about 70k subrequests. However, I'm seeing an unexpectedly high number of KV read operations – specifically 13,919,754 reads – despite only storing around 20 items in the KV namespace and querying them by key.
I've checked my code, and it doesn't seem like there are any duplicate KV reads. The number of reads is way higher than what I would expect from our traffic. Could this be related to caching behavior, strong consistency, or something else I'm missing?
Any insights into how KV reads are calculated in this scenario would be greatly appreciated!
Thank you in advance for your help.

THi @xiaolong01 and @a4amaan, that is correct, there is currently a bug in the dashboard & GraphQL API that is displaying higher metrics than what is accounted on your KV namespaces. We are working on a fix. This does not affect billing.

Just to confirm, this wouldn't impact billing at all, and anyone effected doesn't need to ticket billing to get their bill adjusted or anything like that?

ZHey, trying to write some data to KV with a script I have used previously without issue, now seeing occasional 502 responses through from the API. Is there a current ongoing issue causing this?
NMy application accesses files from the KV-store and have been running into the issue that specifc files cannot be found but they are clearly in the store when checking through the web dashboard.
Specificly it has happened to
every other files seems to work perfectly fine
Specificly it has happened to
/lib/config-DMEbaV5l.jsevery other files seems to work perfectly fine
MWhat's the highest cacheTtl allowed for
.get()Also, editing KV entries in the dashboard is a horrendous experience. Editing a single KV key seems to refresh the entire view for about 5 seconds, preventing me from editing others during that time.
Looking at the requests, it's refetching every single visible entry once I change one of them

MCan always delete the database I suppose
TThanks for feedback, noting this down as something to fix
MAwesome
TLike Mozzy said, delete the database or delete them one by one. What’s the context?
DHello team, just a suggestion, maybe if it would be better if we remove the first part cause it somehow causes an error with toml reader... or perhaps its just my vscode extension..
also.. on the default comments. can this be link be added as well so that not only you have resource for pages.. but also for worker and wrangler.toml configuration as well... https://developers.cloudflare.com/workers/wrangler/configuration/#kv-namespaces

Use a

HI only see an error if you have both?
DI get an error when using the kv_namesapces=[...]
could it be because of the extension I am using?

DDHI see the issue
Dthe rest are just literal comments.. so I guess it doesn't matter?

Why? so does this mean that on the wrangler toml file the kv namespace should be declared above d1 database?

also, isn't wrangler.toml required in deploying apps in cloudflare?

HI use
wrangler.json. It is supported for Workers, but not for Pages
NAny possible answer to why files in the KV store can be unfindable? could it be the caching or something else?
ZIf you make a request for a key that doesn't yet exist, the not found response will be cached for the same TTL as if it were found. Default 60 seconds iirc, but can be overridden
HNote here that it can be raised above 60 seconds, but not lowered
TFor the first time I got the message "Daily request limit exceeded for Cloudflare Workers"
This worker have an average (and pretty stable) of 250/350 writes every day, and I just checked on the dashboard without seeing anything strange. How should I best proceed?
Thank you!

NHi all, when I am using list method and cursor for pagination (https://developers.cloudflare.com/kv/api/list-keys/#list-method). What happens if I have 1 milion keys and when I get a page I trigger delete of that keys and then use cursor to go to the second page? Would cursor have an old list so it will continue serving correct pages even though that I am deleting keys in the background?
Cloudflare Docs
To list all the keys in your KV namespace, call the list() method of the KV binding on any KV namespace you have bound to your Worker code:
THey folks! We just shipped the new Analytics GraphQL API and Dashboard UI for Workers KV 
Now, you can get per-namespace analytics and more details such as cache status and latency information, and it's standardized on the same GraphQL API layer as other Cloudflare products.
Check it out in action (looks even better in person)!

N@thomasgauvin really awesome view and great information source. One thing that I noticed is that if KV is big it doesn't show KV count
MHeya—I assume probably not, but is there a way to tweak the usage limit email threshold? I'm getting daily "you have used 50% of the free tier!" emails... from a cron job that reliably uses just over half of the free tier allotment :D
M(er, wait... no, it doesn't, it uses like 1/3. seems like essentially a duplicate of this thread, I'll stay tuned on that)

EDoes KV have a feature for checking existing keys on write? By default it does not but is there a feature that can be turned on to enable such a thing?
HNo, and no
EI knew but I had to ask anyway. Can you clarify if I'm being paranoid then. I want to store magic tokens(that expire after an hour) and although I've gone to great lengths to make the token unique, there is always that statistically improbable chance that a duplicate token is created within that ttl window. I'm I crazy for trying to check for duplicates when the chance for that is as probable as the sun going out?
EIt also could just be the way I'm implementing the magic token system that invites uncertainties.
HYou could also just use DOs?
