Can you share your code and exactly how you are calling the API?

Do you mean “batching based on a user-defined partitioning key?”

Is your Worker throwing errors? That would cause a retry before you call

Has anyone here tried to integrate CF queues with logstash? What would be the best approach for that, just use the http_poll input?

Can you share your account ID & queue ID? This sounds like a bug if this isn’t working (and would be the first report, hence my questions!)

Eengrtitus Oh....got it Account Id: 6caf95d4a4a1a9be07f3aff69662c84c QueueId: 02b291e03c06...

Thanks. I’d still recommend wrapping your fetch call with a try-catch so the delay is set even if an exception is thrown.

Ohad•5/26/24, 5:42 PM

What’s the recommended way to use queues for logs in rust ? As in, dynamic content .
Currently I’m converting back and forth between serde_json::Value and JsValue. But it feels very dirty.

Hi I am trying to test the delay functionality of Queues and I am unable to get it to work. The msg is consumed almost instantly.

export const producerTest = async (c) => {
  try {
      await c.env.TestQueue.send(JSON.stringify({
      slug: 'test123',
      timestamp: new Date().toISOString()
    }), { delaySeconds: 300 });
    return c.json('Queued', httpStatus.OK);
  } catch (error) {
    console.log(`Error in test ${error.message}`);
    const response = createResponse(
      {},
      {
        message: `Error occured in test ${error.message}`,
      }
    );
    return c.json(response, httpStatus.INTERNAL_SERVER_ERROR);
  }
};

Thanks! This is the second report: we’re looking into it

M

Matt Silverlock•5/27/24, 5:25 PM

Note: so far I cannot reproduce this, with a regular Worker consumer calling

msg.retry({delaySeconds: 90})

msg.retry({delaySeconds: 90})

- messages are only delivered 90s later. The

batch_timeout

batch_timeout

on this queue is 30s.

M

Matt Silverlock•5/27/24, 5:28 PM

Consumer handles the messages, calls

msg.retry({delaySeconds: 90})

msg.retry({delaySeconds: 90})

-> messages are only re-delivered ~90s later. No sooner. Not immediately.

For those playing at home, my consumer is very simple: messages that have a

shouldDelay: true

shouldDelay: true

property get retried with a fixed delay.

max_retries

max_retries

is 10 so they eventually get deleted:

async queue(batch: MessageBatch<Message>, env: Env, ctx: ExecutionContext) {
    console.log(`reading ${batch.messages.length} messages from ${batch.queue}`);
    for (const msg of batch.messages) {
        let latency = Date.now() - msg.timestamp.valueOf();

        let retried = false;
        if (msg.body.shouldDelay) {
            msg.retry({ delaySeconds: 90 });
            retried = true;
        } else {
            msg.ack();
        }

        console.log(`${msg.id} (latency: ${latency} ms | retried: ${retried}): ${JSON.stringify(msg.body)}`);
    }
}

async queue(batch: MessageBatch<Message>, env: Env, ctx: ExecutionContext) {

        let retried = false;
        if (msg.body.shouldDelay) {
            msg.retry({ delaySeconds: 90 });
            retried = true;
        } else {
            msg.ack();
        }

        console.log(`${msg.id} (latency: ${latency} ms | retried: ${retried}): ${JSON.stringify(msg.body)}`);
    }
}

            retried = true;

I was on v2 of wrangler. Upgrading to v3 solved the issue. Thanks a lot.

Eengrtitus No, it never did. It always gets retried immediately

M

Matt Silverlock•5/28/24, 9:34 AM

Per queues - are you also using this locally?

F

Fokke•5/28/24, 8:16 PM

For queues is there a way to force more workers to span for consuming workload? For example, say I have 10 items in my queue, but I want them to be processed as quickly as possible. Can I force deploy 10 workers to deal with that workload?

Basically I want the opposite of max concurrency

Eengrtitus No, i am not using it locally

M

Matt Silverlock•5/28/24, 10:53 PM

OK, thanks. Can you confirm the wrangler version you’re using and open an issue here with a minimal reproduction? https://github.com/cloudflare/workerd/issues/new/choose

Hi!

About Queues pricing, when the Queues is empty and a post-consumer Worker is triggered because of max_batch_timeout, do this cost money ? (may be a "read" from Queue, and may be CPU/Request of a consumer Worker) ?

To prevent that, could we set « set max_batch_timeout = 0 » and « max_batch_size = 1 », to not waste money please?

Do you mean pull consumer?

M

Matt Silverlock•5/29/24, 10:40 AM

A push consumer will not be invoked at all if the queue is empty, so $0.

MMatt Silverlock Do you mean pull consumer?

G

GuillaumeLakano•5/29/24, 10:45 AM

Not a HTTP pull consumer, the automatic push consumer, triggered when either max_batch_timeout or max_batch_size is reached
Good news if it's not invoked when the queue is empty !

M

Matt Silverlock•5/29/24, 11:21 AM

That should not affect it. In my (non) repro, my batch timeout is 30s and my retry delaySeconds is 90s. delaySeconds on an individual message will take precedence over the queue-level settings.

Sinderella•5/30/24, 1:09 PM

I am currently following this example https://github.com/cloudflare/workers-rs/blob/078d15bb60d2b05af0236c7b1370f598f5e17ada/examples/queue/src/lib.rs#L113

I am facing the following error message, similar to Messages in Queue not Processing

Queue test-queue (5 messages) - Exceeded CPU Limit @ 30/05/2024, 19:52:42

Queue test-queue (5 messages) - Exceeded CPU Limit @ 30/05/2024, 19:52:42

I am wondering how does the consumer work. Each message of mine should query a row from D1, make a HTTP request, then update the row in D1, which shouldn't take long.

P

Paul•5/30/24, 11:12 PM

In local development, when I have an api route that triggers a queue using hono, and the consumer simply console logs the message, for some reason it has a delay of 25 seconds before all the console logs come printing out. Any idea on why that is? I would have thought it would be instant...?

P

Paul•5/30/24, 11:13 PM

Code is written with hono.js

This is my producer:

app.get("/test", async c => {
    const message = `Test message. Random number: ${Math.floor(Math.random() * 100)}`;
    await c.env.WEBSITE_QUEUE.send({
        body: message,
    });

    return c.json({ success: `Queued up this message: ${message}` });
});

app.get("/test", async c => {
    const message = `Test message. Random number: ${Math.floor(Math.random() * 100)}`;
    await c.env.WEBSITE_QUEUE.send({
        body: message,
    });

    return c.json({ success: `Queued up this message: ${message}` });
});

app.get("/test", async c => {
    const message = `Test message. Random number: ${Math.floor(Math.random() * 100)}`;
    await c.env.WEBSITE_QUEUE.send({
        body: message,
    });

    return c.json({ success: `Queued up this message: ${message}` });
});

app.get("/test", async c => {
    const message = `Test message. Random number: ${Math.floor(Math.random() * 100)}`;
    await c.env.WEBSITE_QUEUE.send({
        body: message,
    });

    return c.json({ success: `Queued up this message: ${message}` });
});

This is my consumer that simply console.logs the message

export default {
    fetch: app.fetch,
    async queue(batch: MessageBatch<{ body: string }>, env: Environment) {
        for (const message of batch.messages) {
            console.log(
                `Consuming message: ${JSON.stringify(message.body, null, 2)}`
            );
        }
    },
};

export default {
    fetch: app.fetch,
    async queue(batch: MessageBatch<{ body: string }>, env: Environment) {
        for (const message of batch.messages) {
            console.log(
                `Consuming message: ${JSON.stringify(message.body, null, 2)}`
            );
        }
    },
};

export default {
    fetch: app.fetch,
    async queue(batch: MessageBatch<{ body: string }>, env: Environment) {
        for (const message of batch.messages) {
            console.log(
                `Consuming message: ${JSON.stringify(message.body, null, 2)}`
            );
        }
    },
};

export default {
    fetch: app.fetch,
    async queue(batch: MessageBatch<{ body: string }>, env: Environment) {
        for (const message of batch.messages) {
            console.log(
                `Consuming message: ${JSON.stringify(message.body, null, 2)}`
            );
        }
    },
};

Is the JS API the only way to retrieve a list of active queues within a worker?

At what point are queues officially completed? Obviously if something doesn't throw within the queue, it means that you can ack the message and retire it once whatever operations you have are completed (if operations complete fine, then esentially the job is done and you can mark it as completed)?
