It does't seem like the messages get redelivered when calling message.retry() with local wrangler dev?

Hi team, I need to use event notifications with R2 and queues when new objects are created. I have a job written in C#/.NET which is supposed to read messages from this queue. My question is: do you have a .NET SDK that I can use for receiving/acknowledging messages from queues? For example, I think R2 is compatible with AWS S3 SDK and I can use AmazonS3Client with R2, is that the case with queues? Can I use AmazonSqsClient with Cloudflare queues? Or what other options do I have?

You can pull via HTTP - we don’t have a .NET SDK and the SQS API is far less of a defacto standard vs S3, and so we have no plans to support it. https://developers.cloudflare.com/queues/configuration/pull-consumers/

Cloudflare Docs

Pull consumers | Cloudflare Queues

A pull-based consumer allows you to pull from a queue over HTTP from any environment and/or programming language outside of Cloudflare Workers. A pull-based consumer can be useful when your message consumption rate is limited by upstream infrastructure or long-running tasks.

I have built some demos with queues and have not faced the issues. One thing I have done to make sure that there is consistency is adding retries at the relevant places. You can also setup a dead-letter queue. Here's the doc that might be useful: https://developers.cloudflare.com/queues/configuration/batching-retries/#explicit-acknowledgement-and-retries

Cloudflare Docs

Batching, Retries and Delays | Cloudflare Queues

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

Ssouvikinator great I need to try it out. So I assume it's ready for production right?

harshil1712•9/4/24, 10:12 AM

harshil1712•9/4/24, 10:53 AM

You can have the producer and the consumer in the same worker or in separate ones. It really depends on how you want to architect your application. However, for now, when building locally, we recommend having them in the same worker.

Hi! Has anyone seen CPU Execution timeout on queue consumer event? In the worker limits docs they say the limit is 15 minutes of CPU time. But I always get timeout after 32,000ms (according to the worker cpu time dashboard). I could work around that, but I'd like to know if the docs are wrong or if it's a bug on my or CF side.

Michael Wittig•9/5/24, 12:49 PM

Hi! I deleted a bunch of R2 bucket notifications & buckets but I can not delete the queue that was referenced. I always receive the error "cannot delete queue bucketav-rhyglnin that serves as a target for event notifications". I have no buckets left so this is likely not the case. Are there any reqasons for that? Is there something happening in the background before I can delete the queue? If I look at the queue in the dashboard it says "This queue does not have a consumer". Clicking the delete button in the UI is broken as well. I can see the error in the browser logs but not the UI.

johtso•9/5/24, 2:42 PM

hmm, it seems like my messages are being retried immediately after an implicit retry instead of waiting the configured 60 seconds..

[[env.staging.queues.consumers]]
queue = "emails-staging"
max_batch_size = 1
max_concurrency = 1
dead_letter_queue = "emails-dlq-staging"
max_retries = 5
retry_delay = 60

[[env.staging.queues.consumers]]
queue = "emails-staging"

Stockton•9/7/24, 12:14 AM

What would be the benefits of having a producer and consumer in two different workers? Or vice versa?

micooz•9/8/24, 5:22 PM

Queue "consumer concurrency" feature does not seem to be suitable for scenarios that rely on sequential execution.

ytsruh•9/10/24, 1:59 PM

harshil1712•9/11/24, 12:05 PM

Can you expan a bit more on this? Is the consumer queue not picking it up? Can you also share your wrangler.toml config for the queues?

psteinroe•9/12/24, 2:22 PM

hey! is there any (inofficial) goal for queues performance? will it ever be comparable to eg sqs? sending to the queue is currently multiiple 100ms, and it takes multiple seconds for a worker to receive it. and throughput is much much lower at the moment.

kcbrewron•9/13/24, 11:23 PM

I haven't run into messages dropping or batches dropping. I have built some interesting architecture where I have a message-producer API which abstracts all the applications from needing to know about how to send messages. We used a KV bound to the message producer API to know what queue to route to and bind the worker to any queue. I know there are limits to the binding, but this API has made it easy to onboard queues for a few different use cases. I'm ready for this to move to GA. What issues is the team waiting on solving before moving it to GA?

oof2win2•9/16/24, 9:40 AM

is there a plan to have messages be "grouped" and sent that way? i have a merchantId prop on my messages and i want to handle up to 20 messages per merchant, but there isn't really a way to do that right now

oof2win2•9/16/24, 9:41 AM

it would be really neat if i could do that honestly

VoidRanger•9/16/24, 10:15 PM

Hi there, just wanted to know if there is any way to see which buckets are sending notifications to a queue

tadhglewis•9/17/24, 1:07 PM

Couple queries:

Any plans to add a

Message.deadletter

Message.deadletter

method? I have some use cases where I know the message will always fail and it needs manual triage.

It'd be great to have redrive functionality to move messages from the deadletters to processing queue once any issues with the deadletters have been resolved (e.g. temp outage). AWS SQS has similar functionality https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-configure-dead-letter-queue-redrive.html

Jason Barry•9/18/24, 11:25 PM

I don't see wrangler.toml's equivalent of

[[queues.consumers]]

[[queues.consumers]]

referenced in https://developers.cloudflare.com/workers/configuration/multipart-upload-metadata/#bindings -- is that intentional? if so, how does one configure a Worker uploaded from the API to be a queue consumer? I've added

"type": "queue"

ajgeiss0702•9/20/24, 2:09 AM

it is just me, or does delaySecondsdelaySeconds no longer work?

ajgeiss0702•9/20/24, 2:10 AM

it looks like it stopped working on 9/17 around 18:00 UTC

ajgeiss0702•9/20/24, 2:25 AM

its still listed on the dev docs still, so it wasnt removed, was it?

When you explicitly call message.retry() does this still respect the `max_retries` configuration set
