Hi, I want to make websocket server for a game in worker. What does "Max of 30 seconds of CPU time per invocation" or "10 milliseconds of CPU time per invocation" mean? Does my websocket stops if it go over?

Hey @Mike Nomitch | Workers PM regarding your recent message on the announcement channels about containers in the workers platform, we have a very specific use case that is currently being delegated to fly.io which basically consists of the execution of long running tasks in an asynchronous manner, think of it as a job runner that can run a container instance to completion with parameters passed as environment variables.

We basically use it as a way of executing bulk Tasks like post processing on media, AI tasks, report generation, RPAs, puppeteer and other such things where system dependencies are needed.
Our main reason for delegating it to fly.io right now is that they don't impose a time limit so our long running tasks don't get timeouts while still providing quick startup times once the image is cached.

We find that currently no cloud provider provides a complete solution for running asynchronous jobs while just paying for the compute time and providing fast startups (we achieved that with fly.io but it required us to hack around with their platform API and writing our own scheduler) so I think that would add great value to the Cloudflare developer platform.

Essentially what I do is this in my pages workers / functions (next-on-pages) (simplified)

export const getEdgeCacheVersion = () => {
    const startMs = Date.now();
    const edgeCv = await getRequestContext().env.EDGE_CONFIG.getEnvironmentVariable("CACHE_VERSION"); // EDGE_CONFIG reads env variable.

    // Average durationMs: ~100ms, very rarely actually hits 0, but docs says it should run in the same thread mostly?
    const durationMs = Date.now() - startMs;
    
    if (!edgeCv) {
      return null;
    }


    logger.debug("Fetched cache key from EDGE_CONFIG", {
      cacheKey: globalThis.__cacheKey,
      durationMs: durationMs,
    }); // 

    return Number(edgeCv);
}

export const getEdgeCacheVersion = () => {
    const startMs = Date.now();
    const edgeCv = await getRequestContext().env.EDGE_CONFIG.getEnvironmentVariable("CACHE_VERSION"); // EDGE_CONFIG reads env variable.

    // Average durationMs: ~100ms, very rarely actually hits 0, but docs says it should run in the same thread mostly?
    const durationMs = Date.now() - startMs;
    
    if (!edgeCv) {
      return null;
    }


    logger.debug("Fetched cache key from EDGE_CONFIG", {
      cacheKey: globalThis.__cacheKey,
      durationMs: durationMs,
    }); // 

    return Number(edgeCv);
}

Hello guys I need help with cloudflare worker
as I was using K6 Gafana to load-test my worker.

It was went well at the start but then at certain time I cant sent request anymore. I'm not sure wether its the problem from K6 or Cloudflare worker that block repetitive coming request with in short period of time.

if the problem is with my Cloudflare worker, how can I unlock this block feature to test how much can my Cloudflare worker can handle? do I have to upgrade the plan or Are there any better solution to solve this

thank you

ps. I attatched the report file from my K6 to see whats the actual problem.

Executive_Summary_-_scriptjs.pdf18.43MB

Kkian It'll also try `worker` then `browser` if there is no `workerd` key.

I personally use AE but you can't download from that. You can export the data from D1: https://developers.cloudflare.com/workers/wrangler/commands/#export

ehrenmann•6/26/24, 9:58 PM

would maybe hyperdrive be an option?

Unsmart•6/26/24, 10:00 PM

What exactly is your goal? Why are you downloading data locally?

ehrenmann•6/26/24, 10:04 PM

i would like to download it and collect it and then do some study about my traffic

Unsmart•6/26/24, 10:06 PM

Why not just feed it to an analytics tool and use queries in that instead of downloading it? AE is good if you only need 3 months

ehrenmann•6/26/24, 10:08 PM

sorry but im new to this and dont understand completely what you mean by AE

Unsmart•6/26/24, 10:08 PM

and is it possible to read that data externally or so? because i would like to create my own overview with all that information.

Unsmart•6/26/24, 10:15 PM

Yes there is an API you can post queries to

Sstevefrench Is there a limit to the number of concurrent promises running at a time?

Hello, I’m Allie!•6/27/24, 9:54 AM

No, though there is a max number of outgoing connections(6)

Silent•6/27/24, 10:07 AM

Since this is backed by WAF does using it to limit an endpoint stop the requests from counting towards the daily limit?

When you access router.handle now, it’s trying to register a route on the HANDLE verb instead of processing a request… so it fails to respond.

You would need to reduce the requests your Website makes. This can be aided with stuff like SSR, though you would probably still have 2/3 requests per page view

@anthony the limits and allowances are pretty generous on the paid plan though, especially if it's a cron trigger or queue consumer (15 minutes)

I naively thought I could share the logic from my nextjs app with my cloudflare workers but the environment variables is causing quite a bit of issues. Even when polyfilling with

import * as process from 'node:process';

import * as process from 'node:process';

, whenever I use process.env, the nextjs app doesn't understand "node:process". Is it common to simply duplicate the logic for the cloudflare worker? Even my database calls requires a separate env and it's a bit too integrated. Is it common for folks to duplicate their code logic for CF workers or are people commonly able to reuse logic from their app?

Paul•6/27/24, 3:43 PM

Is it common to declare something like globalThis.process = process (imported from node:process) when using cloudflare workers for nextjs and cloudflare worker compatability?

ctx.waitUntil is your friend, hand it a promise and it'll let the response return but not kill the execution
ctx.waitUntil(fetch(..))
