The example (incorrectly) calls

this.state.id

this.state.id

this.state.id

this.state.id, which doesn't directly serialize to JSON. I've PR'ed the docs to fix this: https://github.com/cloudflare/cloudflare-docs/pull/14665 - it needs to be

this.state.id.toString()

this.state.id.toString()

this.state.id.toString()

A

queue() handler accepts a message, the Env, and the context per https://developers.cloudflare.com/queues/configuration/javascript-apis/#consumer

But what are you writing to env? Where would the middleware run? The env from the request (in your producer) is not the same as the one in the consumer. They are decoupled (as they should be)

Hello, I’m Allie!•5/21/24, 7:43 PM

How are you connecting it to Hono? Hono shouldn’t be called at all in a Queue Consumer, Middleware or otherwise

H

And IMO there’s no real reason to use Hono for the Consumer portion anyway(unless you are passing Requests back directly into the 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.

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?

I

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

max_batch_size

max_batch_size is set to

1

1 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

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

msg.retry({delaySeconds: 90})

msg.retry({delaySeconds: 90})

msg.retry({delaySeconds: 90})

msg.retry({delaySeconds: 90}) - messages are only delivered 90s later. The

batch_timeout on this queue is 30s.

Matt Silverlock•5/27/24, 5:28 PM

Consumer handles the messages, calls

msg.retry({delaySeconds: 90})

msg.retry({delaySeconds: 90})

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

shouldDelay: true

shouldDelay: true property get retried with a fixed delay.

max_retries

max_retries

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)}`);

so i'm not sure why the example doesn't
