bummer. alright! is there any plan to integrate this?

DI'm not aware of any immediate plans, but I'd bet it's somewhere in their backlog to investigate
FThanks @Dani Foldi
UAre you getting this error consistently or was it just a one off error?
IShould be resolved now - let us know if you see this error again.
RHow do I query the local kv store? All the wrangler commands seems to be work on the main remote ones
SI have question about the
Does the cacheTtl means cache n seconds start from now, or start from when it is write?
cacheTtl field of KVNamespace.get’s option. Does the cacheTtl means cache n seconds start from now, or start from when it is write?
BIt's from when KV determines to refresh the data from the underlying storage. It's also worth calling out that
cacheTtl & expirationTtl are frequently confused for each other.
LIs there a naming convention for KV namespaces?
ENo, you can name them whatever you like
RHI, I am getting started with workers, and intend to use some KV to store some auth data. I could not find how wise this is security wise. Can KV storage be considered safe to store sensitive data?
KWorkers KV is a global, low-latency, key-value data store. It stores data in a small number of centralized data centers, then caches that data in …
KIf it's critical as well as sensitive, I would always recommend backing up your data to another location.
Even if Cloudflare isn't going to lose your data, it offers no protections against accidental overwrites or malicious actors gaining control & deleting your stuff.

Rit is not critical, and does not need backing up, I have backups. The question is more like, is it securely bound to my workers and my account via cf infra? is it internally encrypted to avoid malicious actor getting the data? Is it bad practice to store auth tokens in there?
KThe linked document covers the encryption aspect
ROops my bad, I recognized the image on the link an though it was a page I had already read. I'll read that now. Thank you
KThe only thing about auth tokens is that KV is eventually consistent so if someone revokes a token, it might still be active depending if it’s cached here & there - by default, that should be less than 60 seconds.
RYeah I have seen that "eventually consistent" remark. But in my use case, it should not be an issue.
SKV GET failed: 500 Internal Server Error getting this error again in Asia Region
Jis it possible with
wrangler kv:key list to dump the key values and metadata too?
Tshould i store JWT
jti in cloudflare KV? I've heard that KV has high latency on cross region access, which could take 60s to propagate data to other region. My service provide token for users to use in their server, which could be placed in a different region from where the token is generatedTEx, I have a customer generated a JWT in APAC region, they take that token and deploy their app in US WEST region
NI spent a good amount of time debugging a stupid mistake, so i'd like to make a feature request: It would be nice if the dashboard marks invisible characters in the key name. (I copied key value pairs from a test namespace to production and in the process i somehow got a tab at the end of my key so the worker couldn't find it.)
MCan you explain more about what you’re trying to achieve? If you are writing the value for the first time it will be available globally. Updates take 60s. Not fresh writes.
Mcc @charlieburnett
CWhat do you mean by the local KV Namespace? The local one isn't a real one and doesn't have an ID
Toh, if fresh write will make data available globally then it's perfectly fit with my use case. My concern now is the latency when I retrieve the data from KV, and pricing too. My current approach is storing JWT
jti in KV with a TTL (or cache data in general). jti will be retrieved in every requests, so low latency and low cost is a very important. My old implementation on my onprem server is deploying a redis cluster, with each redis instance will sit next to the main service in every region for lowest latency. I only write data once, rarely update it and access it many times in its life timeTin the KV document, it said that KV is not a in-memory cache and has significantly higher latency than redis. So storing cache data in kv might not be a great idea...
UHow often do you query this
Or a better option since your customers are deploying into specific locations could be Durable Objects. DOs you can send a parameter telling it where to be created so you can give them an option to select what would be closest to them. And if the DO happens to be created in the same datacenter their request hits its faster than KV but thats a big if the colo they hit has DOs and thats where it gets placed
jti value? If its often then KV will be great because it caches data in the colo it gets requested from so it will be pretty fast. For me I generally get around ~40-50ms on cache hits iirc.Or a better option since your customers are deploying into specific locations could be Durable Objects.

TI'm querying it in every request and I'm having 40-200 request per minute, so 40-50ms is pretty high tho. I'm also using D1 to store data, which takes 10-50ms to query data, so the cummulative sum of data querying time could be 50-100ms per request, plus internet latency then the response could be 130-300ms. I don't know this is an acceptable latency, but IMO, it's pretty high.
UI guess I should say the 40-50ms is e2e of the entire worker request and sending it back to the client.
Uno clue what just the kv request time inside the worker is
Toh okay. So i guess it could only take single digit latency
Tbc averate latency from anywhere not my local computer to my computer is 20-30ms
JI'm using kv to manage the session.
But from today, "error code:500" keeps responding.
Strangely, there is no problem in the local development environment.
kv is being used as an http request. Even if you throw it with postman, it gives you a normal response.

RHi, I got an email from CF to inform me that I reached 50% of my free KV tier. DashBoard shows: Which obvious limit did I miss in the free tier. I though I had 100000 operations perfay.
JThis is just my opinion, but I think what was possible in the local environment was possible because the request was made in Korea.
In Korea, if you don't use Business grade, you will receive requests from other countries when you request them on your PC.

Rthank you @Dani Foldi , I missed the 1000list limit
JI'm spending money on this and I'm debugging it lol
JAre you guys fixing this error? It's not even reflected on https://www.cloudflarestatus.com/ , so should I move on to upstash?
Welcome to Cloudflare's home for real-time and historical data on system performance.

That said, are you able to explain more about the issue? Are you using the Cloudflare API (
That said, are you able to explain more about the issue? Are you using the Cloudflare API (
api.cloudflare.com) to interact with KV or through a Worker? Does this happen consistently when requested in a specific way or from a specific location? And finally, are you able to share the full JSON output you get from the API? Thanks!

Customers have been complaining that they have not been able to log in for six hours.
The funny thing is it's not a region issue.
Registering kv from other pages functions is normally registered
When I fetch a request to read kv in pages functions that is suddenly not working now with v4 api, this is the only one that gets 500 errors answered.
