Hello, I’m Allie!OP•2/7/24, 6:02 PM

Yes, though for fetches, for example, the likelihood of hitting the same server/datacenter is decently low, so unless you are running a very large-scale application, isolates are only shared between requests from a single client

Does CF queues have any concept of fanout jobs? The scenario we're trying to support is sorta similar to batching, a parent job for "srape xyz.com" would be queued up, and that job would enqueue a job for each page on the website, and after all children jobs are finished, the parent would be notified in some way.

Is there any way to accomplish this notifiying the parent job?

Here's how Inngest handles the same scenario: https://www.inngest.com/docs/guides/fan-out-jobs

Yigal•2/15/24, 6:28 AM

I have a situation where I have batches writing to KV, but if there are more than one update to the same key in one batch, the KV is likely to be overwritten and miss updates.
I thought it might be useful to hold the operation of the next batch\message until the first one ends.
How would you go about this kind of issue?

Yigal•2/15/24, 5:04 PM

Is there a way to control the time gap between each batch?

You can set the batch interval. If you need to delay messages, then see queues

Are there statistics available how long it takes for a queue to send it to an consumer? Is it typically less than a second? (not counting retries or something, just the typical case)

Hey question - if you place your consumer for a queue in the same worker that calls it, does it spawn a separate "process" or w/e the right terminology is, that is has its own resources? Or does it run in the same worker process?

Question on batch splitting if anyone knows answer:

If my batch messages are like

{ task_id, subtask_data }

{ task_id, subtask_data }

, and when I call sendBatch all messages in the batch have the same

task_id

task_id

, then can I guarantee that all messages in the consumer have the same

task_id

task_id

? Or will retries or max batch sizes mess with this?

Matt Silverlock•2/28/24, 8:16 AM

No, you can't guarantee that today. The batches you write can't be the same as the batches you receive - because you might write smaller batches than you want to consume (max_batch_size) or wait for (max_wait_time).

dsds10•2/28/24, 9:15 PM

Maybe you could try disabling retry and instead use a dead letter queue with higher timeout, or store fail state in kv and check every message if it was retried, then just let it wait the amount of time you need (since you don‘t pay for wall clock time anyway)

dsds10•2/28/24, 9:24 PM

What I‘m wondering (and sorry if it was already answered here, couldn‘t find it) is, why is there a generous limit of 10k queues per account when you can‘t produce/consume messages outside of a worker? Is this a prep for the http pull? But then again, you can only produce messages with a queue binding, which won‘t let you create a queue per user (at least outside of enterprise plan) although the changelog says this limit is „enabling easier per-user […] use-cases“

MMatt Silverlock No, you can't guarantee that today. The batches you write can't be the same as t...

Conner•2/29/24, 12:39 AM

Smaller batches is okay. I'm worried if fragmented batches might be mixed back together? Sounds like yes
