Do you mean CPU time being more than wall time? 1s of CPU time is counted as 1 core being busy for 1 second, so theoretically if you were using 54/21 = 2.57 cores of CPU at 100% you could get those numbers.

Oh wait, I didn't even notice the minutes vs seconds bit. That's definitely... interesting :lul:

plus workers can use a most a single cpu core right, webworkers or parallelism in general isn't supported

Quantum64•11/23/25, 2:13 AM

but yeah I have used way more than 21 seconds of wall time

Quantum64•11/23/25, 2:14 AM

at least like 100 times more

Isaac McFadyenOP•11/23/25, 2:14 AM

In JS-land yes, I'm not sure whether any of the functions that call into

workerd

workerd

's C++ are multithreaded or not though (i.e. hashing)

Quantum64•11/23/25, 2:15 AM

hm, fair

kleinpetr•11/23/25, 7:52 AM

guys, there's probably a bug in new sdk, especially with error type, since I re-declared the workflow instance types by my own I am getting typecheck error, so when I open sdk the error is now typed just as a string

kleinpetr•11/23/25, 8:20 AM

it's very interesting, because until now I used error.message and I am 100% sure the message is there, because I have this implementation on FE, but if I see to worker-types codebase, it says that this type was made 1 year ago..

avenceslau•11/23/25, 12:35 PM

(@kleinpetr tagging you since you asked) This is mostly incorrect, when the waitForEvent times out the workflow errors (you can wrap the wait for event in a trycatch if you want your workflow to proceed nonetheless). You can send the event before the waitForEvent begins, as long as the instance has been created.

Is it possible to artificially limit the number of concurrent workflow instances, similar to the max_concurrencymax_concurrency setting for consumer Queues?

1984 Ford Laser•11/24/25, 10:13 PM

Is it possible to have multiple waitForEvent()waitForEvent()s running at the same time for a single Workflow instance? I am starting a Workflow when a user begins uploading a series of files to R2, and using R2 Event Notifications to notify the Workflow when each file is complete. I don't think I can guarantee the order of upload so I would prefer to wait for all files to be uploaded at the same time. Otherwise I will use a single

waitForEvent

waitForEvent

that will re-trigger another wait..wait.. until all required files are uploaded

Maulik Tyagi•11/25/25, 10:03 AM

are there any good resources to learn in detail about workflows apart from docs? Would be really helpful to get some resources to see into

wesbos•11/25/25, 10:26 PM

What is the blessed way to keep track of instances? The binding doesn't have a way to list instances, and I found the HTTP API, but that is prod only?

I want to make a dashboard like Vercel's Workflows https://x.com/wesbos/status/1993415964143370302

1984 Ford Laser•11/25/25, 11:19 PM

Not sure if this is a bug or not, but having a period in a

waitForEvent

waitForEvent

type parameter, it breaks things. So like, video.mp4video.mp4 doesn't work, giving workflow.invalid_event_type, even though they're both strings. Does the period need to be escaped?

kleinpetr•11/26/25, 10:12 PM

I've started to get interesting error time to time, would you have any idea?

Hello everyone, I have use cloudflare workflow in my app, now I want to keep my server's database sync with workflow instance what are the approach for it? does cloudflare provides any webhook using which I can sync my workflow with my database? I want to store status and steps of cloudflare workflow in my db.

1984 Ford Laser•11/29/25, 10:42 PM

I'd love to have something similar to Actors/Agents Schedule API where I can have a Workflow peridically poll something to check for status, basically an opposite of

waitForEvent

waitForEvent

. I know I can defer this polling to a DO, but would be useful to do it within the existing flow

ByteBeast•12/3/25, 8:36 AM

Is this a bug or something?

I am trying to select node-workflow-dev but it's keep getting selected first one test-workflow-dev.

ByteBeast•12/3/25, 8:41 AM

When I open workflow list second time it's showing all workflow selected may base with true tick mark and after creating it showing first workflow only in resource.

Hello all, Is there any lifetime limit on the total number of Workflow instances that can be created on a Cloudflare Workflows paid plan?
I’m not asking about rate limits or concurrency, only whether there’s a hard cap over the lifetime of an account.

Yigit Erol•12/17/25, 5:30 PM

I'm having an issue with fetch timeout. I'm calling cloud AI endpoints from a workflow, with 10 minutes timeout set. requests to openai or perplexity apis are working fine for long running tasks with over 2-3 minute response waits, even 5 min plus on occasion, but interestingly, anthropic api is always returning 524 after 100 seconds sharp. Is there a special treatment to anthropic? how can I fix this problem? and what's the point of having 10 minutes timeout if it'll always stop after 100 secs wait? thanks!

Yigit Erol•12/17/25, 5:56 PM

and even increasing proxy timeout wouldn't help cause workflows don't work under a particular zone!
