HHiram Hi @Erisa | Out of office , do you know what is the root cause?

Hey, I can only share what's on the statuspage. If the KV team feel like elaborating here then they can, otherwise we will only give a full incident report (including RCA) to Enterprise customers. If you are one, please write in a support ticket

Hey friends! Any way to bulk delete keys from the Cloudflare Workers bindings?

Frederic Houle•7/19/23, 3:25 PM

I can list and delete one by one, but the API offers a way to do it in bulk: https://developers.cloudflare.com/api/operations/workers-kv-namespace-delete-multiple-key-value-pairs

yet I can't find how to do it from the Workers bindings

It's from when KV determines to refresh the data from the underlying storage. It's also worth calling out that

HI, 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?

kian•7/25/23, 9:42 PM

If 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.

RandomNick•7/25/23, 10:04 PM

it 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?

kian•7/25/23, 10:06 PM

The linked document covers the encryption aspect

RandomNick•7/25/23, 10:07 PM

Oops 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

kian•7/25/23, 10:12 PM

The 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.

RandomNick•7/25/23, 10:31 PM

Yeah I have seen that "eventually consistent" remark. But in my use case, it should not be an issue.

Tony Leung•7/27/23, 3:02 PM

should i store JWT jtijti 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 generated

Tony Leung•7/27/23, 3:04 PM

Ex, I have a customer generated a JWT in APAC region, they take that token and deploy their app in US WEST region

Noel•7/27/23, 11:03 PM

I 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.)

Can 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.

Tony Leung•7/28/23, 1:56 AM

oh, 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 jtijti in KV with a TTL (or cache data in general). jtijti 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 time

Tony Leung•7/28/23, 1:59 AM

in 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...

Unsmart•7/28/23, 2:07 AM

How often do you query this jtijti 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. 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

Tony Leung•7/28/23, 2:19 AM

I'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.

Unsmart•7/28/23, 2:20 AM

I guess I should say the 40-50ms is e2e of the entire worker request and sending it back to the client.
