Are there any plans to lift or increase the current limit of 1,000 external requests per workflow instance? Right now, I'm having to split my workflows just to work around this restriction.

Matt Silverlock•4/11/25, 6:24 AM

In most cases you likely want a Worker to do the routing from webhook -> the correct instance, but if (for example) you can attach metadata to the Stripe payment event or subscription request, you can include the instance ID.

ddsgadget•4/11/25, 10:24 AM

Yeah, but the Stripe webhook that trigger the waitForEvent for a particular workflow instance will by definition fire after the workflow has already started. There is no way to put the instance id into Stripe metadata, because there is no way Stripe will have this information. You can't update stripe metadata before something you don't know will happen will happen. This is the case for nearly every single instance where you would use waitFor. The thing that will trigger the waitFor will fire AFTER the workflow starts or what are you waiting for? So there is no way the external event will ever know what the instance is. Reallly the only way I can see that this can possibly work is that both the Workflow and external event that will eventually trigger the waitForEvent both use a predetermined uniqueID that is considered unique across all workflows. In that way the Workflow instance Id would be created with that uniqueId. But this is quite challenging to get right. In the case of orders, I guess you will have a unique order ID that can possibly be shared by Stripe and the Workflow, but this would have to be created by a 3rd party system, so that Stripe and the Worfklow can both know it.

Dddsgadget Yeah, but the Stripe webhook that trigger the waitForEvent for a particular work...

Matt Silverlock•4/11/25, 10:33 AM

You can set your own instance IDs - you don’t have to create the instance first. For example, the Workflow ID can be the order ID so you have a 1:1 association with those. Or your customer ID, transaction ID, or any other stable identifier that you would otherwise use. Workflows is not unique here.
and/or the Workflow itself can trigger the order, set the webhook, and then wait for the event

I don’t think anything about this example code is impossible to achieve here.

felixnorden•4/11/25, 11:13 AM

What we tend to do is use a shared UUID for various items and prefix with what the consumer is, e.g.,

workflow-${uuid}

workflow-${uuid}

so you can debug more easily too if/when things go south

Where can we make this clearer? Documented here: https://developers.cloudflare.com/workflows/build/workers-api/#create

An ID is automatically generated, but a user-provided ID can be specified (up to 64 characters 1). This can be useful when mapping Workflows to users, merchants or other identifiers in your system.

We kept the tutorial simpler (because otherwise we get feedback that we’re introducing too much!)

ddsgadget•4/11/25, 11:18 AM

Yeah, I see it there now. I'm not sure how you can make this clearer. It's easy to miss that. And also, I generally read examples first and learn from that, and don't go back to the docs unless I need something new or have a bug. And all the examples either don't create the instance and let it be done automatically or they use crypto. So that's how I've been doing it. Maybe have an example with an instance ID that is user-provided? Not really sure.

hugo martins•4/11/25, 6:52 PM

We can retry them, of course — but workflows are meant to be about durable execution. What I was expecting was a way to trigger multiple distinct workflows transactionally with a single request. That way, if the Cloudflare Workflows API goes down or we hit a quota/limit issue, either all workflows start or none do — instead of ending up in a half-started, inconsistent state.

By having to manage retries ourselves, we’re essentially recreating the very problem that workflows are supposed to solve, aren’t we?

Matt Silverlock•4/11/25, 6:58 PM

How are you solving this today/elsewhere? What requires these Workflows to be tightly coupled in a way that can’t be solved by using one Workflow vs trying to spread across many?

(To be clear, this doesn’t mean we wouldn’t consider a transactional API, but it’s non-trivial across multiple unrelated Workflows, because that has a performance + complexity cost)

jasperagrante•4/12/25, 3:59 PM

What's the best way to use Queues to limit the concurrency of Workflows? Or would it be just polling the workflow status and using setTimeout to sleep on the consumer before ack'ing the message?

WWallslide what if you had workflow steps dumping their work into queues

Hello, is there a subrequest limit on workflows? Trying to work out if it fits my use case which I expect to need to make several thousand subrequests to R2. I was looking at a scheduled worker job but I think that certainly does have a 1000 subrequest limit. The docs seem a little unclear in that there is no explicit limit here but it states "Many limits are inherited... [from Workers]".

My workflow works locally but when deployed I get error status on my steps, but I don't have idea how to check the error message.

wrangler tail is not showing any console / error logs
worker logs doesn't show anything either (only invocation)
same for workflows dahsboard (just show status: error)

Kuririn•4/15/25, 2:34 PM

Locally I'm getting:
"✘ [ERROR] An RPC stub was not disposed properly. You must call dispose() on all stubs in order to let the other side know that you are no longer using them. You cannot rely on the garbage collector for this because it may take arbitrarily long before actually collecting unreachable objects. As a shortcut, calling dispose() on the result of an RPC call disposes all stubs within it."

but it runs anyway, maybe that is the problem?

alex (he/him)•4/15/25, 2:43 PM

Really need a way to limit max concurrency per workflow level. I want some workflows to run 200 in parallel while others only 10. Additionally it would be amazing if workflows can be a queue consumer directly, e.g. take 10 from queue when those 10 are done, take another set of 10.. Any update what is planned and timeline?
