I have no consumer setup right now. I'm just trying to see if send is working

ShivekOP•7/2/24, 11:39 AM

it is not at the moment

Yeah, it might fail if there is nothing to write to, I'm not sure

HHard@Work Yeah, it *might* fail if there is nothing to write to, I'm not sure

My config seems correct and I see the resource being attached when I run wrangler dev

Your worker has access to the following bindings:
- KV Namespaces:
  - xxxx: xxxx
- Queues:
  - TREASURY_QUEUE: dev-treasury-queue

Hard@Work•7/2/24, 11:45 AM

Yes, but if there isn't a consumer for that queue, I would guess it might still fail

ShivekOP•7/2/24, 11:46 AM

okay, so both producer and consumers need to be defined before I can write?

Hard@Work•7/2/24, 11:47 AM

Maybe? Tbh, I find it odd that it isn't erroring at all, but just silently failing. If you are able to wait a bit, I may be able to test it out and see if there is something else going wrong

ShivekOP•7/2/24, 11:48 AM

I can wait, I'll try to set a consumer in the meanwhile

ShivekOP•7/2/24, 12:00 PM

@Hard@Work | R2 I'm able to send messages if a consumer is registered. I was assuming that if there are no consumers, the messages will just stay in the Queue. That's not the case. If there are no consumers, the Q didn't register any messages.

PPranshu Maheshwari yes! could you share your code if it's not working on your side?

johtso•7/3/24, 9:29 PM

ok good to know, let me try and make a super minimal example and double check

johtso•7/3/24, 9:32 PM

ok, that seems to be working!

johtso•7/3/24, 9:35 PM

probably what I was noticing was messages not surviving between dev server reloads

letincho5•7/4/24, 10:49 AM

Hi... I need a recommendation. To improve or maximize performance (message processing per second), which is better: 1 worker with 10 queues (and consumer X in each queue) or 10 workers with 1 queue each, with consumer X in each queue?

mlshvdv•7/4/24, 11:35 AM

@Pranshu Maheshwari Hi! Some questions about Queues:

1. Do you plan to support message deduplication (refusing to publish the same message while it exists in the queue + support for 'force' mode to rewrite it)?
2. Do you have any plans to add an API method to be able to remove a message from the queue by its ID or impedance key?
3. Are you planning to change the maximum delay to 1 year (this is supported by Upstash QStash - very convenient)?
4. Is there an estimated release date for Queues in production?

Thanks!

control_crusher•7/5/24, 3:46 PM

Does anyone have example code of how they handled multiple queues, single worker?

Sounds like, bind multiple in repeat bind blocks. Then switch inside the Queue handler based on which queue the messages came from.

Follow-up question... do batches then include messages from any of the bound queues? If so, do we only define the batch settings in a single bind block? @Pranshu Maheshwari

Matt Silverlock•7/6/24, 1:04 PM

Producers are entirely separate from consumers.

- You can write to any queues you bind to as a producer.
- Your consumer will receive messages from only the queues it is configured as a consumer for.
- messages will be batched by queue, but each batch can be from any of the queues you have bound to.

BumblebeeSquare•7/8/24, 8:22 PM

is there message group like feature in queue ? i.e sqs message group

Brett Willis•7/9/24, 4:25 AM

It would be great to be able to manually pause/resume queues (collect from producers but pause dispatch to consumers) and also to purge queue messages. This help both in development and in production e.g. maintenance/migration, disaster recovery, or when dependent services are experiencing downtime. Queues are good for decoupling services for this very reason, and it's good to be able to intervene in emergencies!

minty•7/9/24, 8:30 PM

is it possible to consume messages from a queue from a non-worker piece of code? i.e. the way you can consume messages from SQS using their SDK in the language of your choice via polling/fetching?

@Hard@Work @HardlyWorkin' Hello, when I use R2 GET data when consumers use R2 GET data, it will cause the queue to complete it directly. I tried to use Try Catch to capture the error, but I found nothing. Is this my configuration file wrong? or a bug ? (And this logic is normal in the normal worker fetch)

I am now also having this issue. Was there any workaround other than deploying a new queue and worker?

ajgeiss0702•7/11/24, 11:44 PM

trying to delete the worker throws "script still in use as a consumer for a queue"

ajgeiss0702•7/12/24, 1:37 AM

after manually removing the queue triggers, deleting the worker, and redeploying, the issue was fixed. Still annoying that was an issue though

rcoopr•7/15/24, 9:27 PM

I think the answer to this is simply a no, but might as well ask. Is it possible with queues to process a task as soon as a single message is recieved, and dismiss the remaining messages that join the same batch?

I'm imagining the queue as a debounce of sorts, and this would be the

leading

leading

option for it.

Use case is something akin to logging, but latency is quite important here. Using batch timeout of ~3-5s if its relevant

Matt Silverlock•7/16/24, 4:57 AM

Why not set the max batch size = 1? Or just ack() all the messages you don’t care about in a batch (which means they will deleted) and only “process” what you want?

rcoopr•7/16/24, 7:19 AM

I have a lot of duplicate API requests coming from separate instances of the same web page (going to some external API and don’t care about the response) and I’m looking to reduce the load on the external API and ‘dedupe’ requests via CDN/workers/queues. So a batch size of 1 would be like using the API directly I guess.

rcoopr•7/16/24, 7:20 AM

Basically I want:
Receive first api request: forward it on
Any duplicates within the next 3s, ignore

edit: ideally with POST requests, and the duplicate calls are triggered, in theory, at the same time. So when I tried simple caching with GET requests, the cache wasn't updated before duplicates came in

Hhannes I think a better approach is to just use in-memory cache of worker for dedupe-de...

rcoopr•7/16/24, 4:03 PM

is that just using the cache api? I tested using caches.defaultcaches.default but the requests seemd to hit before the cache write and subsequent read had updated

rcoopr•7/16/24, 4:04 PM

although that was in worst-case testing

I have no consumer setup right now. I'm just trying to see if send is working
