```js export const app = new Hono (); export default { async fetch(request: Request, env: TEnv, ctx: ExecutionContext) { const validatedEnv = envSchema.safeParse(env); if (!validatedEnv.success) { console.log(validatedEnv.error); return Response.json({ message: "Invalid ENV variables." }); } return app.fetch(request, validatedEnv.data, ctx); }, async queue() {...} }; ``` I just thought i'd be able to access some in-memory context set by my fetch middlewares, but the queue consumer is isolated from that, so I just created a DB client manually to do operations within the consumer. My flow is `Web -> route endpoint -> queue producer -> queue consumer -> process messages`

in producer worker I am getting

workers.api.error.queue_handler_missing

error when deploying. the producer worker doesn't handle the queue and in wrnagler.toml i have only producer part of the configuration.

I am using cloudflare queues to build a data pipeline. My goal was to push a bunch of messages in queues and have workes process them as quickly as possible. However hitting some limitations and wondering if there is a way around this.

I want processing to happen as fast as possible and so ideally my workers scale up when there is more than 1 message in the queue. I don't mind paying a little extra for additional workers.

I know there is a way to configure the maximum number of consumers, but is there a way where we can define a minimum number of consuming workers?

Ian•5/21/24, 11:53 PM

specifying a minimum doesn't really make sense. It should just start assigning more consumers if there are enough messages. Make sure your

max_batch_size

max_batch_size

is set to

so that it doesn't assign a batch of, say, 5 messages to a single worker.

Hi there, I am using workers and queues to process large no of events. I have few questions
1. Is there a way to monitor queue performance and raise an alert in case of any issues? Same for workers?
2. Is there a way I can setup logs for queues and workers? I see an option to upload the logs to r2, would like to know if there is better option to access then and perform search quickly.
Thank you for your help

Ian•5/23/24, 6:06 AM

I have a monorepo (managed by LernaJS) that has a cloudflare pages package and a queue consumer package. When I start both packages in dev mode they both seem to set up their own

.wrangler

.wrangler

directories and seem to be isolated, so they don't share a queue. To make them able to talk to the same queue do I need to use

--persist-to

--persist-to

on both?

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

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',

    }), { delaySeconds: 300 });
    return c.json('Queued', httpStatus.OK);
  } catch (error) {
    console.log(`Error in test ${error.message}`);
    const response = createResponse(

    return c.json(response, httpStatus.INTERNAL_SERVER_ERROR);

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) {
    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) {
    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)}`);

        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)}`);
    }

Eengrtitus Oh..Not the experience here. It gets retried immediately. Not sure if this matt...

Did it work previously for you at all?

vs

sendBatch

should make no difference.

What version of wrangler are you using? Local will be all the difference here!

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?

Matt Silverlock•5/29/24, 10:40 AM

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.
