Hello, I’m Allie!•4/26/24, 11:12 AM

No, I meant put it on a non-existent subdomain of your domain

Hello, I’m Allie!•4/26/24, 11:12 AM

Since you own it, then only you could break it

Hello, I’m Allie!•4/26/24, 11:12 AM

I was just using richa.rdricha.rd as an example, I don't know what your actual domain is

RichOP•4/26/24, 11:12 AM

ah right, got you. Yes I think that sounds like the safest bet

RichOP•4/26/24, 11:15 AM

Also, even if I switched it out for our domain, I'd still need to use

caches.default

caches.default

to ensure we can purge it globally (i.e. with "Purge Everything")

Hi everyone

Lucho•4/26/24, 2:10 PM

Im trying to make Inserts in my D1 Database and i would like to recieve de surrogated key of each insert i make, but it looks like line 42 does not return this new ID

Lucho•4/26/24, 2:10 PM

does someone know how to fix this?

Dawson•4/26/24, 6:30 PM

does CF Cache just use KV?

Dawson•4/26/24, 6:30 PM

curios as to how it’s so fast

Dawson•4/26/24, 6:31 PM

does it use the priority latency that you get when you pay for workers instead of the free plan?

DDawson does CF Cache just use KV?

Chaika•4/26/24, 6:33 PM

Which cache? The Cache API? The Cache API is entirely colo/datacenter local, evicting assets based on access frequency

Chaika•4/26/24, 6:34 PM

plan shouldn't matter

Dawson•4/26/24, 6:34 PM

just saw a “always lowest latency” or something along those lines. the cache has a 8ms time where as my hono api with a hello world json at the base route takes 30

Dawson•4/26/24, 6:34 PM

just curious as to what makes such a difference

i believe so, the one that caches based upon headers which requires a custom domain

Chaika•4/26/24, 6:35 PM

sounds like you're talking about the normal cf cache (not in front of a worker/in a worker, in front of a normal origin), vs workers executing?

Dawson•4/26/24, 6:36 PM

yea that sounds right. Sorry, not familiar with the workers side of cf

DDawson yea that sounds right. Sorry, not familiar with the workers side of cf

Chaika•4/26/24, 6:37 PM

I was just asking because the opposite is expected, and CF has publicly stated before Workers are cheaper for them (as in, less latency, as cache is spread out through the DC, but Workers can run right there) then Cache hits are. For me a simple worker returning html is ~50-55ms, and cache is somewhere between ~50-60ms

Dawson•4/26/24, 6:39 PM

interesting, not too sure why that’s happening then

Chaika•4/26/24, 6:39 PM

do you have smart placement enabled or anything?

Dawson•4/26/24, 6:39 PM

possibly i’m close to a Cache data center? it’s a dramatic difference

Dawson•4/26/24, 6:40 PM

i do but last i checked it said i didn’t have enough data

DDawson possibly i’m close to a Cache data center? it’s a dramatic difference

Chaika•4/26/24, 6:40 PM

all DCs can execute Workers, same as all can do Cache

DDawson i do but last i checked it said i didn’t have enough data

Chaika•4/26/24, 6:40 PM

check the cf-placement response header

Dawson•4/26/24, 6:41 PM

cf-placement: local-ORD

cf-placement: local-ORD

Dawson•4/26/24, 6:41 PM

Dawson•4/26/24, 6:42 PM

Im currently comparing my latency to a service like unkey where their latency is dramatically lower, both of us use cf workers

Chaika•4/26/24, 6:42 PM

Does the Cf-Ray response header for both return the same location?

Dawson•4/26/24, 6:44 PM

Just ran on a different endpoint (195ms-> 5ms) and it has the exact same cf-ray

Chaika•4/26/24, 6:44 PM

based on that header count it looks like they're both workers, but you're saying one uses cache and the other one doesn't, or am I misunderstanding?

Chaika•4/26/24, 6:45 PM

(I would make sure to send a handful of requests as well to make sure the connection and everything is warm before looking at the response, REST clients don't make the best benchmarking tools)

CChaika based on that header count it looks like they're both workers, but you're saying...

Dawson•4/26/24, 6:45 PM

Im really just curious how I can get my latency down lower, a endpoint with nearly 0 extra computation ontop of hono takes 3x as long to execute

CChaika (I would make sure to send a handful of requests as well to make sure the connec...

Dawson•4/26/24, 6:46 PM

ah, did not think about that. let me push without a cache and check the numbers

Dawson•4/26/24, 6:46 PM

Semi related, hows the experience with KV / D1 for a db and ratelimiting? Currently using turso and upstash and the latency is pretty high

Chaika•4/26/24, 6:47 PM

KV <- uncached two central stores, cached is still ~20-30ms slower then normal cf cache/workers
D1 -> single location for now, only in Durable Object supported locations as well

For Rate limiting, there is a binding you can use in Workers now to use that colo's/dc's normal ratelimiting

DDawson ah, did not think about that. let me push without a cache and check the numbers

Chaika•4/26/24, 6:49 PM

ah I'm just a bit confused on exactly what you are comparing. If it helps, here's a simple worker with Enterprise routing that returns the url requested: https://quick-test.workers.tylerobrien.dev/, no cache or anything

Dawson•4/26/24, 6:50 PM

30-50ms, seems to be the same as my endpoint without cache headers added

Chaika•4/26/24, 6:51 PM

are you close enough to ORD that 7ms is physically possible or it could just be local cache of whatever utility you are using/something else?
could try pinging their hostname and seeing icmp latency

WebDev0323•4/26/24, 6:51 PM

Hello, How are you? everyone!
I created the worker, do you know how to integrate with my project?

Dawson•4/26/24, 6:51 PM

I am pretty close to a datacenter, not sure if its 7ms close

Chaika•4/26/24, 6:52 PM

what's the endpoint of unkey that you are testing? Curious if I can see the diff at all

Dawson•4/26/24, 6:54 PM

I was testing last night, let me find the url real quick

DDawson 30-50ms, seems to be the same as my endpoint without cache headers added

Chaika•4/26/24, 6:55 PM

oh it may be helpful to explain as well: No matter what cache headers you return from a worker you'll never be able to use edge cache unless you specifically use cache api in the worker (which is of course an invocation even just to get a cached response)

Chaika•4/26/24, 6:55 PM

Workers are a layer in front of cache

CChaika oh it may be helpful to explain as well: No matter what cache headers you return...

Dawson•4/26/24, 6:56 PM

I used the

hono/cache

hono/cache

package inside of my middleware, they covered everything else

Dawson•4/26/24, 6:56 PM

I just specified a cache name and maxage

Chaika•4/26/24, 6:56 PM

ahh ok sounds handy, probably cache api under the hood then

Chaika•4/26/24, 6:57 PM

The Cf-Cache-Status header is an easy way to tell the cache status of an object. If it's missing, didn't even try cache

Dawson•4/26/24, 6:57 PM

curl -XPOST 'https://api.unkey.dev/v1/keys.verifyKey' \
  -H 'Content-Type: application/json' \
  -d '{
    "key": "3ZgvH8KKWrP8W8J25xU1KBeN"
  }'

curl -XPOST 'https://api.unkey.dev/v1/keys.verifyKey' \
  -H 'Content-Type: application/json' \
  -d '{
    "key": "3ZgvH8KKWrP8W8J25xU1KBeN"
  }'

This was what I was using, 150 first hit, then 30-40 after that

but what if `.rd` became a TLD and somebody bought it and put CF in front of it, woudl they be able
