Hi guys, I need assistance to fix this issue: Too many API requests by single worker invocation. I have paid workers account. I am using Workflows alongside Queues to fetch, process, and store data.

D

daniel•10/18/25, 5:53 AM

hey is there a way to do per-user queues when triggering Workflows? Either natively within the Workflows or by using Queues to trigger workflows? I would like to be able to have per-user queues when triggering workflows via API but also when creating workflows from within another workflow

Tuna•10/18/25, 2:55 PM

Hey everyone!

Can someone help clarify how workflow memory and CPU limits are applied across steps and nested steps?
I’m trying to understand whether:
Each step gets its own CPU and memory allocation, or
Nested steps share the parent’s resource limits.
I tried looking this up in the docs, but the explanation wasn’t very clear. Any insights would be appreciated!

TrueBrain•10/19/25, 7:57 PM

Hello!

The Worker attached to a Workflow shows a lot more requests than the amount of invocations to the Workflow. Is this normal? Is this hibernation at work, or some other mechanism?
My workflow has a lot of

sleep("10 minutes")

sleep("10 minutes")

sleep("10 minutes")

sleep("10 minutes"), so I would assume it hibernates a lot

The docs state the pricing of a Workflow is per invocation; so can I ignore the amount of requests the Worker is showing me? Or are both charged? Or how does this work?

Any insights are appreciated

PS: possibly related, but there are also a lot of "cancelled" requests, the metrics tell me. Can't find any details on what "cancelled" means in this context.

I just came to share this experience and found many comments saying the same. I hope they remove this limit for workers and add more built-in features, such as rate limiting, mechanisms to handle backpressure, child workflows, etc.

Hello, I need one help. I have one workflow with some do steps, if any step got failed and it's maximum retry also got failed so can i retry it manually by any way? cloudflare doesn't provide API to retry specific step manually but by doing any hack can I achieve manual retry for any step?

D

D Trombett•10/25/25, 9:46 AM

Hey not sure if this is a bug or it's expected: Ruleset Engine docs specify that we can use

cf.worker.upstream_zone

cf.worker.upstream_zone

to identify if the request comes from a Worker but I noticed that this value is empty when the request is from a Workflow. I'm using this to allow requests to a host only to subrequests from my own workers (and thus Workflows)

D

D Trombett•10/25/25, 10:04 AM

Oh wait after investigating a bit I think that the value is not empty but wrong? Instead of my zone (example.com), like requests from my worker, CF-Worker is set to example.workers.dev which doesn't really make sense since my dev url is disabled

DD Trombett Oh wait after investigating a bit I think that the value is not empty but wrong?...

H

Hello, I’m Allie!•10/25/25, 7:07 PM

Something like p-map can be useful if you care about concurrency over a bunch of async tasks + simplifies failure handling: https://www.npmjs.com/package/p-map

but if you just need a while loop, use a while loop!

Just note that (this is not specific to Workflows) that

while (condition) { await step.do(...) }

while (condition) { await step.do(...) }

while (condition) { await step.do(...) }

while (condition) { await step.do(...) } will block on each

So I am really confused about the use cases of Workflows vs Queues. Seems like anything you could do in one you could also do in the other. Are there specific parameters (like limits, costs, performance, etc.) that I should keep in mind when deciding?

P

Paul•10/29/25, 9:34 PM

I have a pattern I'm using now where a Consuming Worker is pulling events off a Queue and then it just starts a Workflow. Are there plans to support Workflows as Queue consumers, so we can drop the consuming Worker form the flow?
