i'll just put these here

again, first time trying out cloudflare, but hard to be aws

Proprietary storage engine afaik

HHello, I’m Allie!Wonder if it were faster/slower if you read from Upstash with Workers...

✦ xcaeserOP•9/19/23, 2:57 PM

shouldn't KV be optimized for workers? and maybe closer in region?

should've gone for foundation db

Hello, I’m Allie!•9/19/23, 2:57 PM

There is some work being done on it, but right now it is dual-zone Europe and Americas with a cache

Hello, I’m Allie!•9/19/23, 2:57 PM

So if you aren’t in the US/EU, you might get slower reads

developer exp is top notch tho (from terminal as well), way better than raw aws

✦✦ xcaeser should've gone for foundation db

Hello, I’m Allie!•9/19/23, 3:00 PM

FoundationDB(Apache licensed) was released just 5 months before KV, so it might have been that they started work on it before it was viable

Hello, I’m Allie!•9/19/23, 3:01 PM

Though I would note too that Vercel Edge is Workers too

Hello, I’m Allie!•9/19/23, 3:01 PM

So for any non-platform-bound applications, they should perform about the same

nop it's aws afaik

Hello, I’m Allie!•9/19/23, 3:05 PM

That’s their core(I.E. non-Edge). That’s also why they are so particular about the APIs that the Edge Runtime does and doesn’t support

Hello, I’m Allie!•9/19/23, 3:05 PM

Because the Edge Runtime(WorkerD) is V8, but not Node

Vercel's Edge Functions are built on top of Cloudflare Workers. The runtime is designed for any similar provider, but we've chosen Cloudflare for now because they have an amazing product.

thx for sharing, reading now

✦ xcaeserOP•9/19/23, 3:10 PM

okay let me try the worker with vercel kv in this case and see if it's better

✦

✦ xcaeserOP•9/19/23, 3:29 PM

how to get around this? Uncaught ReferenceError: process is not defined
cloudflare workers don't use node right?

✦

✦ xcaeserOP•9/19/23, 3:34 PM

nvm, followed upstash cloudfare quickstart

HHello, I’m Allie!Also, wouldn't this more be a comparison of CF KV vs. Upstash?

✦

✦ xcaeserOP•9/19/23, 3:37 PM

you're right, switched to upstach. Cloudflare KV is very very slow

✦

✦ xcaeserOP•9/19/23, 3:41 PM

still aw seems to be faster for now;

Unsmart•9/19/23, 3:50 PM

you show 2 responses for the other platform one of which is faster one of which is slower so

✦✦ xcaeser still aw seems to be faster for now;

What are you measuring? Puts or Gets?

should've gone for foundation db

The magic with KV is its unlimited scale and getting faster the more requests you give it, it's made for read-heavy cases, like for example Cloudflare Pages uses it
https://developers.cloudflare.com/kv/learning/how-kv-works/

You can signal for it to cache results longer as well, and stream back responses, ex

   let value = await env.KV.get("index.html", {cacheTtl: 86400, type: "stream" });
    return new Response(value, {
      headers: {
        "content-type": "text/html"
      }
    })

   let value = await env.KV.get("index.html", {cacheTtl: 86400, type: "stream" });
    return new Response(value, {
      headers: {
        "content-type": "text/html"
      }
    })

(It is eventually consistent by design, but by getting it to cache for longer you're not going to see updates until cache expires or if you write in same location. (KV 2.0 which was delayed aimed to solve this by checking every minute in the background for updates, but it was delayed due to issues))
It's pretty fast, once its cached locally ~20ms or less

What are your preferred ways of securely accessing a Worker route from an AWS Lambda? I’ve done the reverse before, undecided on what makes the most sense for the other way around.

mTLS?

Amnon•9/20/23, 8:07 AM

Hey,
I'm using Workers to push some logic to the request and proxying the request to the origin backend
When combining that with the Dynamic URL Rewrite Transform Rule it seems like the Transform Rule is triggered two times - from the client to the worker and when proxying the request
In my Dynamic Transform Rule, I used -

concat(“/v1”, http.request.uri.path)

concat(“/v1”, http.request.uri.path)

and ended up with

/v1/v1/<original_req_path>

/v1/v1/<original_req_path>

I tried to adjust the Custom Filter Expression with no success (skipping the rule every time the URL starts with

/v1

/v1

works but doesn't feel robust enough)
Any idea how to overcome this behavior?
Thanks

Hi folks,

I have worker route in my site example (miton.com)::

route value us wildcard / and it is pointed to some worker

Here all the requested from any domain or wildcard domain connected with this site are coming to worker route

I need to by pass some of domain example "javi.milton.com" not to go to worker route

Because i have pointed "javi.militon.com" to R2 bucket

javeed•9/20/23, 9:03 AM

I have create new route for "javi.milton.com" and disabled route withour choosing any workers

javeed•9/20/23, 9:03 AM

but still no luck, it is keep pointing to / --> workers

You can use Unbound, which gives you up to 30 seconds of CPU time.

if you only do hashing on the client, you're essentially storing the "raw" password, just transformed, which I don't recommend
