Both 3 queries return an empty array

is maybe the date incorrect? I used 24h tho

I was using the queue name, but seems like the queue ID is different from the slug

Ashley•1/25/24, 12:07 PM

Interestingly on this one, the queue shows 1 (out of 4) messages on the dashboard when I poll, but the graph shows 4 in the backlog... I know there's the bug so more just more info. Also, if you manage to fix it, could you let me know it's resolved so I can re-try my implementation please?

A

Ashley•1/25/24, 1:23 PM

Also, related, but... should I be hitting CPU limits when consuming? It seems... really weird I'd be hitting a CPU limit considering I'm on standard pricing, and it should be able to run presumably for... a while? (it is running for at most 10 seconds, but most should be I/O)

Adi•1/28/24, 4:23 AM

Hey all, I had a question around the v8 serialization that Queues does to save objects that can't be json serialized.
I'm guessing under the hood it does something like this

const v8 = require('v8');
// Serialize an object into a buffer using v8
function serializeWithV8(obj) {
    return v8.serialize(obj);
}
// Convert the Buffer to a byte array (Uint8Array)
const byteArray = new Uint8Array(buffer.buffer, buffer.byteOffset, buffer.byteLength);
// Now you can send the byteArray over the network

const v8 = require('v8');
// Serialize an object into a buffer using v8
function serializeWithV8(obj) {
    return v8.serialize(obj);
}
// Convert the Buffer to a byte array (Uint8Array)
const byteArray = new Uint8Array(buffer.buffer, buffer.byteOffset, buffer.byteLength);
// Now you can send the byteArray over the network

const v8 = require('v8');
// Serialize an object into a buffer using v8
function serializeWithV8(obj) {
    return v8.serialize(obj);
}
// Convert the Buffer to a byte array (Uint8Array)
const byteArray = new Uint8Array(buffer.buffer, buffer.byteOffset, buffer.byteLength);
// Now you can send the byteArray over the network

const v8 = require('v8');
// Serialize an object into a buffer using v8
function serializeWithV8(obj) {
    return v8.serialize(obj);
}
// Convert the Buffer to a byte array (Uint8Array)
const byteArray = new Uint8Array(buffer.buffer, buffer.byteOffset, buffer.byteLength);
// Now you can send the byteArray over the network

However, I can see that the v8 api is not available in workers under

nodejs_compat

nodejs_compat

.

I was looking to making an API interface around queues for a project. Is there a chance that we can get v8 added to nodejs_compat? Is that something the team is already looking into?

fwiw you can see how it works at https://github.com/cloudflare/workerd/blob/5d27f8f7f1f9b584f673d2f11c9032f5a776ec55/src/workerd/api/queue.c%2B%2B#L33-L128

K

kian•1/28/24, 4:28 AM

it's not done in JS, so the V8 API isn't needed to be exposed

Adi•1/28/24, 4:30 AM

Right, that makes sense. I suppose, this is a feature / compatibility request then

H

Hello, I’m Allie!•1/28/24, 9:49 AM

One argument that could be made against there is the fact that the V8 Serialization API is not stable, so for example if you were to serialize something in the browser, send it to a Worker, then try to deserialize it, there is no guarantee that it would suceed

H

Hello, I’m Allie!•1/28/24, 9:50 AM

You would have to ensure that both the browser and the Worker were running the exact same version of the serialisation system, which unless you control all of the clients that request your Worker, would be basically impossible

Adi•1/28/24, 9:54 AM

Oh really? Ok, that's good to know. I was unaware of that complexity, I thought v8 serialization would work in a stable way across node versions

H

Hello, I’m Allie!•1/28/24, 9:56 AM

A newer version of the serializer should be able to read older versions. The issue is when you have an older version trying to read a newer version

H

Hello, I’m Allie!•1/28/24, 9:57 AM

It would cause even more pain were you to store the serialized objects somewhere, as if you ever have to roll back the serializer version, you now have objects that are unreadable

H

Hello, I’m Allie!•1/28/24, 10:04 AM

I would probably recommend defining your own serialization format that you control. It doesn't have to compile down to JSON(you could probably make it work with ArrayBuffers), but just the fact that you know/control the format means you can manage upgrades/downgrades yourself

Are there any known limits with sending a message to a queue while consuming a message from the same queue? I have a pretty simple case where I have a consumer that posts messages to the same queue it is consuming from and the

env.QUEUE.send(...)

env.QUEUE.send(...)

is called but the consumer never receives the message. No errors. If there isn't a known limit then I'll pair my case down to the most minimal case, but wanted to check here first.

Matt Silverlock•1/29/24, 5:59 PM

Not a design limitation. A consumer can write back to the same queue (mindful of message loops / potential cost implications!)

All right, thanks. Yes, and very aware of the infinite loop possibility.

Al Hill•1/30/24, 5:25 PM

I have a producer worker which processes a big array of data and chunk it into pieces to send it to a queue, which is connected to a consumer. I have dimensioned the batches and the messages for not exceeding the maximum batch size, the maximum message size and the maximum subrequest of the consumer worker.
It seems to work, the produces prepares the data and send it to the queue, the queue receives all the messages... and the consumer only receives the first of them. No error in any part of the flow.

I don't know if I'm misunderstanding the queues but I'm pretty confused right now

I have being trying to lighten the work of the consumer and divide it in more messages but the problem is the same, only the first one reaches the consumer

The consumer delay seems to be very very big, but I don't know if I can do anything about this
