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?

P

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?

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

Hey folks, fresh Queues user here. I am having issues with queue messages not being processed after they are sent back for a

.retry(12 hours)

.retry(12 hours)

.retry(12 hours)

.retry(12 hours), and I can't figure out whether I've mis-configured something or am hitting an edge case.

I produce queue messages in batch from my Pages website, it is basically a set of payloads for emails to be sent out, some to be sent out immediately (message has a field

after: now.toISO()

after: now.toISO()

after: now.toISO()

after: now.toISO()), and some upon delay (message has a field

after: remindOn.toISO()

after: remindOn.toISO()

after: remindOn.toISO()

after: remindOn.toISO(), typically 3-5 days from now). The are 0-3 batches of these messages per day sent out worldwide, as in these are not high volume.

The messages are received by a Workers consumer, generated from a standard Cloudflare workers template. The relevant bit is the

.retry({delaySeconds: X})

.retry({delaySeconds: X})

.retry({delaySeconds: X})

.retry({delaySeconds: X}) of messages which should not be processed yet: if the

after

after

after

after field of the payload message is in the future, I am sending the message back for a retry of up to 12 hours, because it is the documented maximum I found.

What happens, is that the messages I've sent for a long retry don't seem to process until there is a fresh new unrelated message added to the queue, which seems to trigger the re-processing of

.retry()

.retry()

.retry()

.retry()-ed messages. This doesn't seem to happen globally either, but rather per region, as in that "fresh new unrelated message" will only trigger the re-processing of geographically proximate messages. E.g. I had somebody in Germany visit my website on Sept 11 and fill out the booking form for Sept 16 lesson; they received the "immediate" messages, but the "reminders" got stuck in limbo until Sept 11 until a completely different person somewhere in Russian filled out the form which triggered new messages to be added to the queue.

So far I've tried to work around this issue by having a "ping" message being sent to the queue every 5 minutes, which seems to help a little – the messages in my local region are now not getting stuck (I am located in Canada, and it seems to help in NA), but it doesn't prevent messages from getting into the limbo stage in EU (assuming there aren't more regions by which Queues are partitioned, which I don't know about).

Why don’t you use https://developers.cloudflare.com/queues/configuration/batching-retries/#delay-messages the delaySeconds property when creating the queue message?

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

But you could acknowledge the message and send it again with delay instead of retrying

U

UNOwen•9/22/24, 11:47 AM

Re-sending messages might be a viable short-term workaround, but it would only function if sending messages is 100% reliable, and it doesn't seem like this "limbo" behavior is clearly intended – I am either misusing the retry API, or it has an edge case I am hitting. Re-sending the message would side-step the issue without documenting the details for future users (the "limbo" behavior is confusing and unlike other queues I worked with so far) or fixing the edge case.
