What do you mean, doesn’t work?

Ghuyz I just want to say i love wrangler

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 6:33 PM

Cloudflare team is truly brilliant most the time.

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 6:34 PM

My dream is someday to work at cloudflare.

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 6:35 PM

Curious what the "right" of the f is?

kian•12/17/23, 6:36 PM

ID of the server.

Kkian ID of the server.

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 6:41 PM

Thank you.

HHello, I’m Allie!What do you mean, doesn’t work?

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:02 PM

Haven't found an easy way to call it from workers to get a summary of # of API calls (i.e. to shut customer off)

Hello, I’m Allie!OP•12/17/23, 7:06 PM

You need to use the API, via a fetch request

Will try that out shortly thank you :). Will analytics be more cost effective than KV? And any slowness with it?

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:12 PM

I.e. if a worker uses an analytics engine does it have to go to another DC or centralized source?

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:13 PM

Oh wow looks like it’s got lots of features

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:13 PM

Will swap over to that…

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:14 PM

Does each DC have locally available analytics engine endpoints that are eventually replicated across?

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:16 PM

Got it. Probably Kv better for now as I could be upwards of a million requests a second

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:16 PM

Which for Kv is $25 to write and $5 to read

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:17 PM

Smart

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:17 PM

Very smart

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:17 PM

Thank you!

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:17 PM

You mean by specificity the read cache?

KKDX_MW | Kaddex.xyz / Ecko.xyz Which for Kv is $25 to write and $5 to read

DaniFoldi•12/17/23, 7:18 PM

just to be accurate, KV reads are $0.50/M, and writes/lists/deletes are $5/M

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:18 PM

I.e. at same interval as the KV population?

DDaniFoldi just to be accurate, KV reads are $0.50/M, and writes/lists/deletes are $5/M

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:18 PM

Thanks I thought it was $1 so cheaper than I estimated

DaniFoldi•12/17/23, 7:18 PM

exactly, and storage is also $0.5/GB/mo

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:19 PM

What is cache API?

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:19 PM

Do you mean by setting cacheTtl?

DDaniFoldi exactly, and storage is also $0.5/GB/mo

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:20 PM

So best bet is write to analytics engine, then have a worker run every 300 seconds or so and pull the data out to populate the KV pair with the latest total sum requests

Original message was deleted

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:21 PM

So use cache engine to serve the data instead of KV?

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:21 PM

Ahh got it

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:21 PM

So read from Kv cache it via worker then re-read after x time period

DaniFoldi•12/17/23, 7:22 PM

cron for each customer doesn't work though, you still have the 1000 subrequest limit, so unless you call the worker with a service binding, I recommend looking at DO alarms

KKDX_MW | Kaddex.xyz / Ecko.xyz So read from Kv cache it via worker then re-read after x time period

DaniFoldi•12/17/23, 7:23 PM

although not recommended for all workloads, you can put cache in front of KV, so you only even query KV if your cache (which is free) has expired or evicted

DDaniFoldi cron for _each customer_ doesn't work though, you still have the 1000 subrequest...

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:23 PM

Are you able to get a service binding into analytics engine?

DaniFoldi•12/17/23, 7:23 PM

whereas you pay for cached KV reads

DDaniFoldi although not recommended for all workloads, you can put cache in front of KV, so...

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:23 PM

This is great idea I’ll check that out, cache is per data Centre in each location?

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:23 PM

So like Sydney there are five data centers it looks like

KKDX_MW | Kaddex.xyz / Ecko.xyz Are you able to get a service binding into analytics engine?

DaniFoldi•12/17/23, 7:24 PM

service bindings are bindings for workers from another worker (or the same one)

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:24 PM

So there’s be five caches essentially

DaniFoldi•12/17/23, 7:25 PM

here's an unofficial map of all pops: https://statusmap.cloudflare.community, although there are more datacenters, not sure where you can get a list of those, but do you need a list?

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:26 PM

When you say call the worker with a service binding does that bypass the sub request limit?

DaniFoldi•12/17/23, 7:26 PM

kind of, but there's also a limit to how many times you can call the worker

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:26 PM

So let’s say I have worked A which goes through my 4000 customers using the analytics engine and populates the KV pair. If I use a service binding from worker B to worker A and have the from on worker B would that bypass the limit?

DaniFoldi•12/17/23, 7:26 PM

it resets the 1000 limit, but there is also a 32 recursion limit, so you can't continue resetting indefinitely, and it also counts as another worker invocation

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:27 PM

Got it so I could theoretically get up to 32,000 invocations in one go

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:27 PM

Presuming I recursively called at the end

Constantin•12/18/23, 12:49 AM

is there a problem with workers deployment/dns

Constantin•12/18/23, 12:52 AM

the wroker is beeing deployed via wrangler having this config

{
    "compatibility_date": "2023-12-06",
    "main": "src/index.ts",
    "account_id": "1cca8d8eb0cc2de3f76e07b7164f222e",
    "placement": {
        "mode": "smart"
    },
    "env": {
        "main": {
            "name": "worker-app-proxy",
            "route": {
                "zone_id": "0ae46da72468555b0841b3615fc6f14e",
                "pattern": "*.app.nefele.ai/*"
            }
        }
    }
}

    "compatibility_date": "2023-12-06",
    "main": "src/index.ts",
    "account_id": "1cca8d8eb0cc2de3f76e07b7164f222e",

                "pattern": "*.app.nefele.ai/*"
            }
        }
    }
}

all good, however there's no Worker DNS record, and the url is not reacheable

kian•12/18/23, 1:03 AM

Did you create a DNS record for that route?

kian•12/18/23, 1:03 AM

Workers won’t do that for you unless you’re using custom domains.

Constantin•12/18/23, 1:13 AM

yep, i did ..

What do you mean, doesn’t work?
