What version of wrangler are you using?

Isaac•6/12/24, 8:27 AM

Hey, I'm seeing a severe delay (up to 20 mins) in messages being consumed by my worker after (roughly) 5pm BST. Is there any way I can fix this on my side?

(it's near instant at 9am BST)

MMatt Silverlock What version of wrangler are you using?

I’m not sure off the top of my head (I can check in a bit), but I also tried running the dev command with

npx wrangler@latest dev —test-scheduled

npx wrangler@latest dev —test-scheduled

and the same thing happened

Matt SilverlockOP•6/12/24, 1:47 PM

The last two times this came up it was because folks were not using a later version of wrangler - e.g. see the note here: https://developers.cloudflare.com/queues/configuration/batching-retries/#delay-messages

ajgeiss0702•6/12/24, 1:49 PM

I would assume that using the command I sent (with wrangler@latest) that it would always use the latest available version of wrangler?

ajgeiss0702•6/12/24, 1:53 PM

looks like the wrangler in my repo was outdated, but not that outdated. It was on

3.58.0

3.58.0

(where the latest appears to e

3.60.2

3.60.2

npx wrangler@latest dev

npx wrangler@latest dev

did appear to run with

3.60.2

3.60.2

. The weird thing is that when I updated it in that repo, it seems to be working now

RRohit Verma is there a way we can get the r2 file created event in the queues?

Hey guys, playing with the CF workers and stuff and got a question on queues
Sending message to a queue takes 500ms. In rare cases it’s 200s, but usually 500ms+. I mean this code takes 500ms:

const start = Date.now();
await queue.send({ timestamp: new Date() });
console.log('--->', Date.now() - start);

const start = Date.now();
await queue.send({ timestamp: new Date() });
console.log('--->', Date.now() - start);

Is it always like this or it’s just temporary system issues?

Sam•6/14/24, 3:29 PM

The list messages in queue option don't seem to work correctly. It always returns 4 items, even when more than 100 are in the queue. So specifying 50, will return 4. Specifying 2, will return 4, etc...

Sam•6/14/24, 4:22 PM

Oh wait, the value of "max_batch_size" in wrangler is being used in the dashboard?!? That's pretty annoying.

Fabio•6/16/24, 11:05 PM

Is it possible for a route that calls instead of calling the worker to call the queue that will call the worker?
Because if it is necessary to call a worker on the route that adds it to the queue and this queue calls another worker to process it, I will have 2x the number of executions

Fabio•6/17/24, 12:55 PM

I have a route that calls a worker that makes the same request to a lambda. What I wanted to do was use the Queue, but I thought I could use it directly in the route, but in reality from what I understand I will have to create an 'add to queue' worker, with a route trigger that receives the request data and then adds it to the Queue, which itself will call another Worker that will make the request to the lambda.
Would that be it? Because then each request will have 2x more requests to workers

You need a Worker to write to a Queue, yes. But you can consume directly from a Lambda - https://developers.cloudflare.com/queues/configuration/pull-consumers/

Not currently, no. You can delete the queue / recreate it.

ajgeiss0702•6/22/24, 5:40 PM

is there a reason that in the dasboard, there are 1-3 datapoints between the real data that is 0?

ajgeiss0702•6/22/24, 5:42 PM

basically i have a cron job that runs every 3 hours and adds a bunch of items to the queue, delayed to be spread over the next 3 hours. For some reason, the dashboard displays that there are 0 delayed messages between these "real" datapoints

Sohaib Muhammad•6/24/24, 7:44 AM

@ajgeiss0702 are you sending messages using send() method with delayed options OR you are using sendBatch() for sending all at once and use a global configuration for delaying

a5000•6/24/24, 2:02 PM

Hi there! Do you all have any recommendations on local dev for an api worker that takes requests, puts them in a queue, and the consumes the queue items with workers.ai. I know queues are beta and not fully supported by wrangler. Also I believe there's a limitation with local queues where they have to be in the same

wrangler

wrangler

project, so I can't run 2 node projects pointing at the same local queue.

I'm unable to spin up the project if I have a queue producer and workers ai enabled.

ajgeiss0702•6/24/24, 5:51 PM

I use send() to apply a different delay to each one (so that they’re spread out across those 3 hours)

Matt SilverlockOP•6/25/24, 4:06 PM

You can (should) retry in your producer Worker. There’s no case where 100% of requests succeed. Assume 99.9% success - if you have 1M queue sends, and .1% fail, that’s still up to 1k failures to potentially retry.

Matt SilverlockOP•6/25/24, 4:06 PM

You can retry in your code when you use a try-catch - no need to expose those failures directly to users.

Matt SilverlockOP•6/25/24, 4:12 PM

Note that this isn’t specific to us - any API can fail intermittently at scale. Catching and retrying (before eventually failing) is a common strategy.

SteffTek•6/25/24, 4:12 PM

yeah, i know that ^^

Hello, yes, my queue simply stopped working, all requests were failing and throwing this error, my alternative was to create a new queue and connect it to my worker, after doing this the worker started working correctly again without throwing any more errors.

Hi @everyone! Pranshu here. I’m a product manager at Cloudflare and I’ve recently taken on Queues. I’d love to learn more about how all of you are using Queues, and how you'd like to see it improve.

I’d especially love to hear from folks building startups. I’ve been a 2x founder myself, so I’ve been in your shoes!
