This is a Cloudflare internal error (e.g. no specifics to share). You can typically retry - are you seeing that repeat?

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 Silverlock•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.

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.

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.

Note, I didn't make any changes to the code, I simply moved to a new queue and things started working again

Can you share your accountId and the (previous) queueId? Both are safe to share publicly.

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!

I'm working on a startup, and I'm unable to use queues for proof-of-concepts without first upgrading to a paid plan. I'm currently working free tier for PoCs and don't want to invest financially into a solution service until revenue is generated. Any chance of getting a free tier for queues?

Avat•6/25/24, 10:14 PM

Hello, I'm looking for advice how to handle canceled request.
So, I'm using an API which sends array of objects to my worker, which then iterates through this array and sends every object to queue.

The problem is, this API closes the connection almost immediately and the worker gets canceled.

How can I keep worker up until whole object is being sent as messages to queue?

Queues not working on remote dev is a friction point for me! I mostly do all of my local dev without using wrangler dev remote, but as I’m working on an app that uses browser rendering, I have had to switch to remote as browser rendering does not work locally.

I could also phrase this problem as browser rendering not working locally tho, is that coming at some point? Everything else feels frictionless locally

I have no doubt that I will benefit from it after having services; but right now, it is impossible to build PoCs for services with queues. My goal is to build a service on free tier, establish market, then upgrade to increase my limits to account for the new traffic. But without queues in my free tier service, I am unable to launch a new service that harnesses queues.

Welcome to running a business. Sometimes you need to spend before you have revenue.

Paul•6/26/24, 12:46 AM

When writing multiple queue consumers, they always need to be defined in the root default export right? So if we have multiple queues in one worker, the only way to define multiple consumers is to have a switch statement or equivalent in the root queue-key export and route the message to the right consumer right? One would assume I would need to have a "name" or equivalent key in the message body as a result, in order to route the message to the correct consumer right?

Paul•6/26/24, 4:19 AM

I’m using queues to batch download media files for my saas. I just wonder the rationale for why there’s only one queue consumer function and it needs to be defined in the root.

It’s fine because we can still route the message to the correct queue consumers by some name or type key inside the message body to but I’m curious about the rationale for this architecture… unless this is just common and I’m just not familiar with it

SteffTek•6/26/24, 4:38 AM

We are building a fully digital, mobile point of sales system and are using queues for asynchronous jobs, like receipt creation, regulatory required backup jobs, syncing to other APIs and cash point closings.

Without queues we wouldn't be able to do this since some requests take longer than 30s.

Edit: we have a crazy technology stack. CF as backend, flutter for the mobile app (so far so good) and hecking Delphi for the windows env :pain: best startup ever

I'm a big fan of CF Queues and especially the Consumer Worker model! The biggest thing I wish for is easier way to publish items to a Queue from external systems (like external Kafka Topics).

For example I'm using Debezium for change data capture on an external Database.
This then leads me to having to use Kafka -> HTTP -> Worker -> Queue to get these messages to a CF Queue which is a lot of overhead and you have to deal with all of the usual Webhook headaches

oof2win2•6/26/24, 8:00 AM

i heavily agree with this. queues have a intended scenario of working on a per-customer basis, which i understand to be one queue per customer - each customer can then be a HTTP consumer and get+ack messages, but the issue is publishing messages to the queue. creating a queue is already possible with the CF api, the question only is if you can create enough access tokens for the queues
