CChaika Worker Custom Domains or Routes?

Spunkie•10/31/24, 4:08 PM

ah ya.. I guess it would not work because a the cname would just get replaced by a cname for the worker

Eelpupper 40-50 :pepethink:

Chaika•10/31/24, 4:08 PM

I'm counting end to end from my perf monitoring, from the worker it's only going to be ~10ms or so I'd imagine

Chaika•10/31/24, 4:08 PM

err actually I think I have that data lol

As far as I understand CNAME flattening only remove intermediary CNAME pointer records and the CF nameservers respond directly with A/AAAA records?

Chaika•10/31/24, 4:09 PM

yes which happens anyway when proxied

Spunkie•10/31/24, 4:10 PM

routes don't cause a cname to be applied, only custom domains ya?

CChaika err actually I think I have that data lol

elpupperOP•10/31/24, 4:10 PM

u would be an absolute life saver if u do

r2 cached, timing in worker

elpupperOP•10/31/24, 4:11 PM

how big is your data?

elpupperOP•10/31/24, 4:11 PM

the file you requested

Chaika•10/31/24, 4:11 PM

10kb

I don't think size is too much of a factor though, once you get it streaming -- it well streams back at pretty decent speeds

Chaika•10/31/24, 4:13 PM

KV's pretty solid

SSpunkie routes don't cause a cname to be applied, only custom domains ya?

Spunkie•10/31/24, 4:13 PM

@Chaika sorry I confused myself but to be clear, a CNAME that is proxied and flattened can or can not be intercepted by a worker with a route setup to catch something on that cname/subdomain?

Chaika•10/31/24, 4:13 PM

flattening shouldn't matter at all, not even sure why it shows up on proxied records currently

Chaika•10/31/24, 4:14 PM

Proxy inherently needs to unflatten it to connect, as the client sure can't

Chaika•10/31/24, 4:14 PM

So the answer is yes* as long as you're not CNAMEing to a CF for SaaS partner on the legacy integration like Shopify

CChaika KV's pretty solid

elpupperOP•10/31/24, 4:14 PM

beautiful

elpupperOP•10/31/24, 4:15 PM

might have to resort to KV

CChaika What you store in memory/global? no File system? They don't have any

elpupperOP•10/31/24, 4:17 PM

how long is it presistent for in memory

Eelpupper how long is it presistent for in memory

Chaika•10/31/24, 4:18 PM

as long as it's getting frequent requests but it's complex in reality

Chaika•10/31/24, 4:19 PM

Workers run on the same edge machine which handled your original request. There is no affinity to routing to a specific machine which already has your worker running. There is keepalive. Chance of two random connections hitting the same machine and thus getting the same worker is pretty low, espec when it can be any machine at any cf pop. However, keepalive can make it confusing since your browser would keep hitting the same

Chaika•10/31/24, 4:19 PM

If you're worried about cold starts, CF does a good job of that, taking advantage of the tls handshake to warm up the worker during initial connection, elimating cold starts unless you've got a big worker/a lot of code in global scope

Chaika•10/31/24, 4:20 PM

but def don't rely on global scope for anything

elpupperOP•10/31/24, 4:20 PM

its not about coldstarts

elpupperOP•10/31/24, 4:20 PM

its more about i have templates that i need to serve

elpupperOP•10/31/24, 4:20 PM

static html, css

If you're using KV and you want to measure it's real easy and nothing fancy, just performance.now() and writing to Cloudflare's Analytics Engine, ex:

        var startReq = performance.now();
        await env.KV.put(key, req.body, { // or get
    
        });
        var getDur = performance.now() - startReq;
        if (env.AE)
          env.AE.writeDataPoint({
              blobs: [],
              doubles: [getDur],
              indexes: [key]
            });
...

        var startReq = performance.now();
        await env.KV.put(key, req.body, { // or get
    
        });
        var getDur = performance.now() - startReq;
        if (env.AE)
          env.AE.writeDataPoint({
              blobs: [],
              doubles: [getDur],
              indexes: [key]
            });
...

Then you can use Grafana w/ AE and build nice dashboards relatively easily

quick question since you seem like you know the ins and outs. How would you go about serving static content? with wildcard domains

would you just store everything in a r2 bucket, then have a worker in the front responding with the proper files?

elpupperOP•10/31/24, 6:19 PM

Different

Chaika•10/31/24, 6:20 PM

For customer domains you need CF For SaaS on top, and you can't do wildcard with CF For SaaS without Enterprise

Chaika•10/31/24, 6:20 PM

you could go Workers Static Assets, pay nothing for requests like pages, and use wildcard routes for your own domain

Chaika•10/31/24, 6:21 PM

then you can use CF For SaaS easily with plain Workers

Chaika•10/31/24, 6:21 PM

if you need lots of customer assets though, well you can only have 500 workers even on paid, and there's limits on assets/would be messy to intermingle, you'd probably want to just throw their custom stuff into KV

Chaika•10/31/24, 6:22 PM

KV is 25 MiB max though, per key (just like Pages and Workers Assets)

Eelpupper What about queues

Chaika•10/31/24, 6:26 PM

what about them?

var startReq = performance.now(); await env.KV.put(key, req.body, { // or get }); var getDur = performance.now() - startReq; if (env.AE) env.AE.writeDataPoint({ blobs: [], doubles: [getDur], indexes: [key] }); ...
