excellent, thanks!

DanGamble•3/10/24, 9:46 PM

If you retry a single message, does it go to the to the back of the queue or does it just get tried in the next batch?

Dalist•3/11/24, 9:17 AM

Hi everyone, is there any updates for this product yet?
https://developers.cloudflare.com/pub-sub/

Or is it built within Cloudflare Queues now?

question: with pull, will items sit in the queue for a long time if they are not pulled yet? whats the time limit?

Is there no way to use cloudflare-queue without a worker (external service)? I am implementing an API that doesn't use HTTP, so I do not think I can use a worker for this.

Old Man Maker•3/17/24, 10:35 AM

Hi - I have a worker that is the queue producer. Is in .toml and exposed through env.
This is a DO - intending to recieve a message from WS and forward that message into the queue.
I have set this up exactly the same as other workers that I have connected to queues - but this one does not recognise the queue types as shown in the image.
What am I missing here?

Old Man Maker•3/17/24, 10:41 AM

yeah - build types - not sure how my DO project is so far behind. Updated and all types now resolved.

Not at pages at all. Create a worker that sends request to your app for now if you want it.

Is there a recommended way to orchestrate deploying multiple workers and pages at the same time that share common resources?

Hello everyone, planning to test the queues with a test project. Here the plan: I have a webapp which visualizes data from a D1 Database. The Database gets its data from a service which runs in a local network. Can I create a queue which populates the d1 data. I want to build a docker app which runs locally on that local network and pushes new data to that queue. Can I use the Cloudflare queues „outside of Cloudflare“?

Amblamps•3/19/24, 4:44 PM

Matt SilverlockOP•3/19/24, 9:33 PM

https://developers.cloudflare.com/queues/examples/publish-to-a-queue-over-http/ - you can write to a Queue, you just need to write a Worker to do that for you! The Worker can (of course) accept HTTP requests that write to the queue.

КАПИТАН ПСИНА (ВУФ)•3/20/24, 3:37 PM

Hi everyone.
I have a pages deployment that I am trying to add queues to and I ran into an issue with registering the worker there as a consumer.
I have a _worker.js that I have setup as a producer from settings in Cloudflare web interface, but there is no setting to bind it as a consumer. Is this possible at all? Or will I have to just create a separate worker that I can register as consumer via a toml file?

curious - the backlog looked normal, and rates never get close to the limit (see weekly charts) - this is a constant process that's been running for over a week now with little variation. Queue send failed: Queue is overloaded. Please back off.Queue send failed: Queue is overloaded. Please back off. was received from workers all over the world at around the same time (calling .send.send on a queue).

Almost feels like an error message that would come from a DO request queue overload. Would it be possible for your team to track down what causes this message? I don't see any clues in workerd. Perhaps there can be an internal backup in whatever internal queue magic sits behind .send.send and the queue storage?

Ideally from an abstraction pov, .send.send would only fail when exceeding the msg/s limits (globally) or some truly edge case node failure where it couldn't even save to any sort of recoverable internal storage.

FFedera How are people looping the incoming batches from the queue?

Correct. The consumer (the queue() handler) is effectively its own entity. Not something you need to
