There's a relatively well-documented

There's a relatively well-documented issue with writing to KV where metadata is supposedly optional, but required in the type definition within the cloudflare-typescript library. Easy, right? Just pass in a dummy empty metadata object on your writes to KV! WRONG!! If you just do that, your value gets stored in KV as an object like { value: XYZ, metadata: {}}. Not super intuitive, I'd rather just store XYZ. So then I learned:...

Hello everyone,

Hello everyone, I'm encountering an issue with the Cloudflare Worker KV where I get an empty array when trying to retrieve multiple keys at once. When I run the following code, it returns an empty array:...

hi guys, will Cloudflare eventually

hi guys, will Cloudflare eventually support bulk delete or bulk put in cloudflare KV using in Workers? CF workers has a limitation of 6 concurrent connection at the same time and it's really painful to bulk put like 20 - 30 items using the SDK in workers.

Does KV have any native backup systems by chance or is it expected to do this on your own?

hey guys

hey guys I was wondering if there's a way, possibly through a support ticket, to get a dump of a KV namespace I have tried exporting the data via a script, but since the API only allows reading 100 records at a time, and I have 1.96M keys, it's gonna take ages 😅 Is there a better way?...

i was trying to build a POC where i wanted to add items as a tree. keys would be /master/child1, /master/child2 and then i would call list with /master/ prefix to get the child item keys and since the doc says list will always return keys in alphabetical order, i was hoping when delete child1, the next list1 call would return /master/child2 as the first item. however, for about a minute the list calls keep returning /master/child1. is this the expected behavior? i was making the list calls from...

Not to throw my own engineer under the bus, but he says " Hyperdrive is just a connection pooler with a very light caching layer. It makes connecting to postgres quick yes, but not a true caching layer like KV." -- it sounds like we have some fundamental misunderstanding of the product difference?

Is the removal of the API rate limit just for the KV endpoints? Or is there a more general discussion around removing that limit altogether

👋 Hi, I have a question about Metrics

👋 Hi, I have a question about Metrics and how to interpret them. OI the image, there is read latency of our KV store. Is this correct interpretation? - P99 390ms: means that 99% of read operations are done under 390ms - P50 18ms: means that 50% of read operations are done under 18ms...

Is Cloudflare KV a good option for low-latency needs, should I use it in Next.js and NestJS? We need to add it directly; we can't use the KV because it's causing latency. Is there any way to avoid this?

hello here, I can't find correct information online, is the list() function performant, or should I implement some sort of indexes inside an object instead of relying on list() ?

I racked up 700K (free plan) delete operations testing worst case cleanup operations, then 1.27M with a paid plan. The paid plan includes 1M deletes, so will I be charged fractionally for 270k deletes? Or rounded up to $5?...
