Bulk update can only be used with the

Bulk update can only be used with the REST API or the Wrangler CLI for now, which means I need to create an API key. I’m wondering if this can be used with Workers KV bindings in the future, as that would be more convenient.

Just wanted to confirm there is no Change Data Capture capability with KV, right? I was hoping I could send CRUD events to a Queue so I can trigger other behaviors in response to the KV state changes. I know I can do this in a Worker, but was looking for a storage level solution, like DynamoDB Streams so each Worker interfacing with the KV don't need to handle this concern. Is this on this roadmap and if not can I request it

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:...

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?...
