No, you can't guarantee that today. The batches you write can't be the same as the batches you receive - because you might write smaller batches than you want to consume (max_batch_size) or wait for (max_wait_time).

Hello, is there any estimate on when the feature of adding a delay will be released if a retry occurs in a message? My messages are trying immediately after failing and then leaving the queue, causing me to lose data

Sébastien Morel•2/28/24, 8:33 PM

hello here, I could debug that sending a simple payload to a queue is making my producer worker crazy slower. would you see a reason? Do queues have locations ?

Sébastien Morel•2/28/24, 8:40 PM

I am talking about hundred of milliseconds to .send.send to a queue. (that if I understood it right) must be awaited...
I can't be the only one experiencing that, right ?

Sébastien Morel•2/28/24, 8:51 PM

ha! that's interesting

Sébastien Morel•2/28/24, 8:51 PM

cause I have logged more, and the

send

send

takes between 200ms and 300ms

Sébastien Morel•2/28/24, 8:53 PM

I think the document should mention that, cause I won't be the last following it

Maybe you could try disabling retry and instead use a dead letter queue with higher timeout, or store fail state in kv and check every message if it was retried, then just let it wait the amount of time you need (since you don‘t pay for wall clock time anyway)

dsds10•2/28/24, 9:24 PM

What I‘m wondering (and sorry if it was already answered here, couldn‘t find it) is, why is there a generous limit of 10k queues per account when you can‘t produce/consume messages outside of a worker? Is this a prep for the http pull? But then again, you can only produce messages with a queue binding, which won‘t let you create a queue per user (at least outside of enterprise plan) although the changelog says this limit is „enabling easier per-user […] use-cases“

Matt SilverlockOP•2/29/24, 12:41 AM

Correct - batches aren’t kept separate because most folks don’t want that. If you do, then set your max batch size to 1 + send your batches as a single array when calling send()

We’ve discussed allowing batching by an object/JSON key, which would achieve this correctly. No timeline yet.

Conner•2/29/24, 12:44 AM

Makes sense okay

Conner•2/29/24, 12:44 AM

Yeah the option for consumer delay / send delay is a bigger ask haha

Conner•2/29/24, 12:46 AM

Extra note on this though
For batching by parent key, would be amazing if another event was fired for when all child tasks all done
So could track success/fail of parent based on child tasks
Having to hit db everytime for that rn

Alisson Acioli•3/1/24, 11:48 AM

@Matt Is there a forecast for the delay in messages that failed to be rerun again?

Alex•3/1/24, 9:02 PM

Has anyone been having very long delays for messages to be picked up by consumers?

excited to start adding queues to production workers once it hits GA - two things I'm curious about:

1. does adding a

Queue

environment binding limit the colos where the producing

fetch

handler can run, or change the behavior of the worker in any way?
2. does adding a

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

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?
