Does

wrangler.toml

wrangler.toml

in the code editor from the dashboard work?
I added

tail_consumers = [{service = "tail"}]

tail_consumers = [{service = "tail"}]

tail_consumers = [{service = "tail"}]

tail_consumers = [{service = "tail"}] in the file but it didn't work.
I'm sure my tail worker is called

tail

tail

and the worker has

tail(event)

tail(event)

tail(event) function.

Tail workers are quite hard to debug, you can try the dashboard logs and potentially create an endpoint in that tail worker that mocks some of the tail events to test if your worker is doing what you expect to do.

Question in regards to service bindings, reading environment variables and latencies. I've a worker called Edge Config that exposes 2 RPC functions, setSecretsetSecret and getSecretgetSecret. setSecretsetSecret updates the secrets of itself using the Cloudflare REST API. getSecretgetSecret returns the environment secret binding. I expected it to be close to 0 latency for doing an RPC call to Edge Config and returning a secret, but it ends up being around 147ms147ms for the RPC call to get an environment variable. The whole reason I have this setup is to have close to 0 read latency to get some dynamic config values.

It's a Pages -> Workers service binding, both have smart placement turned off. Is this latency normal, how can I further reduce this? Any other recommendations to have dynamic config with close to 0 latency for reads?

there's tons of companies and projects which scan the entire web and ip space, not particularly harmful,espec not to a worker which isn't going to be vuln to anything

Chaika•6/24/24, 4:52 PM

if you want to try to block those, disable your workers.dev for that worker and use Custom Domains/Routes to bind your worker to your domain, and you can use a rule like not cf.edge.server_port in {80 443}not cf.edge.server_port in {80 443} to block all traffic to non-standard ports

ItsWendell•6/25/24, 2:53 PM

I managed to bring this down to ~91ms~91ms by setting the edge config worker to smart placement I guess? But the binding latency is still not 10ms<10ms< which I expect since service bindings should run on the same thread / isolate right? In the docs it states:

"Service bindings are fast. When you use Service Bindings, there is zero overhead or added latency. By default, both Workers run on the same thread of the same Cloudflare server."

And all the RPC call does is read a environment variable. Curious if anyone has any insight into this?

Natan Parmigiano•6/25/24, 10:48 PM

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", {

      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.
