So, if I have this line:

await kv_storage.put(id, JSON.stringify(data))

await kv_storage.put(id, JSON.stringify(data))

and I want it to go to a queue instead, how would I write that?

kian•1/31/24, 12:50 PM

await env.QUEUE.send(data);

I got stuck at figuring out how to declare this interface in js:

export interface Env {
   <MY_QUEUE>: Queue<any>;
}

export interface Env {
   <MY_QUEUE>: Queue<any>;
}

kian•1/31/24, 1:27 PM

Interfaces are just types.

kian•1/31/24, 1:27 PM

You don't need them in JS.

Batching and Retries · Cloudflare Queues

When configuring a consumer Worker for a queue, you can also define how messages are batched as they are delivered.

I moved a function that edits KV entries inside a queue, but I keep loosing messages, sending a bunch of edits will surely drop some of them.
All of the requests are well received and logged, but the end result is still missing data inside the KV storage.
It's possible that an edit to the same KV will be done more than once per batch, is that an issue?

Manav•1/31/24, 8:03 PM

Hi there, im very new to queues! I have been experiencing consumer delays of about 2000+ seconds. I also see in my workers metric that i get "Excedded CPU limits", what i am trying to do in this queue consumer is to parse out website data such as links, and recursively find upto 300 links and then take the data from all the links and ingest it into a vector database.

Tried multiple things
- changed batch size to 1
- changed batch timeout to 1
- max retries to 1

but nothing has helped so far. Any help would be much appreciated

pages queue consumer

alex35mil•2/3/24, 3:49 PM

Can somebody suggest how to debug on a local machine the following issue? There is a queue that accepts an image url.

max_batch_size

max_batch_size

is set to

.

A consumer:
- downloads an image
- reads its headers to get the dimensions
- puts the image into r2 bucket via binding
- reports the status to a durable object via binding.

When I throw at this queue around 65 images, after ~45 images, the queue gets silently terminated. No errors, no warnings, nothing. It just silently stops processing a current image, and everything stops.

I was wondering why the naming of queues is so restrictive compared to KV namespaces etc

Invalid queue name: invalid queue name: STATE-CHANGES. Must match
  ^[a-z0-9]([a-z0-9-]{0,61}[a-z0-9])?$ [code: 11003]

Invalid queue name: invalid queue name: STATE-CHANGES. Must match
  ^[a-z0-9]([a-z0-9-]{0,61}[a-z0-9])?$ [code: 11003]

Aren't Queue calls Isolated?
I have a simple

queue

queue

function which starts by logging the number of messages logged so far. The

Logger

Logger

is a simple ES6 module I wrote by myself.
If

queue

queue

calls were isolated (by creating a V8 isolate for each call), then the logged number of messages should always be Zero.
But it's not. It's always increasing which means all

queue

queue

calls are being made within the same running environment.
IS it how it's designed?
I was under impression all Workers calls create a new V8 isolate and there is no shared data/memory between the calls.

Hello, I’m Allie!•2/7/24, 5:59 PM

It's definitely not guaranteed to be a new isolate

Hello, I’m Allie!•2/7/24, 6:02 PM

Yes, though for fetches, for example, the likelihood of hitting the same server/datacenter is decently low, so unless you are running a very large-scale application, isolates are only shared between requests from a single client

Does CF queues have any concept of fanout jobs? The scenario we're trying to support is sorta similar to batching, a parent job for "srape xyz.com" would be queued up, and that job would enqueue a job for each page on the website, and after all children jobs are finished, the parent would be notified in some way.

Is there any way to accomplish this notifiying the parent job?

Here's how Inngest handles the same scenario: https://www.inngest.com/docs/guides/fan-out-jobs
