Is there a way to make Workflows process one at a time, instead of multiple running at once?

What is the time limit for a step to finish in a workflow that has multiple steps

alex (he/him)•6/30/25, 6:07 PM

Any way we can get step.waitForEventstep.waitForEvent not count towards the total step count per workflow, similar to step.sleepstep.sleep

alex (he/him)•6/30/25, 6:08 PM

We have a hard time to strucutre our workflows to stay under the 1024 step limit. We either hit the cpu time limit of 5 minutes if we do multiple tasks in one step, or we hit the step limit if we do each task in a separate nested workflow

This has been an issue forever. I have posted about it many times and others have experienced the same thing. I have never seen Cloudflare acknowledge it, though. Supposedly, if you JSON stringify the response, you won't see an error, but even Cloudflare doesn't do that in any of the examples. Bottom line, this is a bug in workflow, but it doesnb't seem like they will ever fix it.

Seekerdasbatatas•7/2/25, 9:01 AM

While the invocation might show the invocation as errored/canceled, it's not directly related if your workflow instance threw or not, it's a side-effect of how we guarantee durable execution internally. You should refer to the instance logs (in the Workflows tab, in dash),to see if an instance failed or not.

But this is something that we should definitely fix in our logging pipeline, so sorry about that :MeowHeartCloudflare: , we'll try to get it fixed :soontm:

ac•7/2/25, 12:18 PM

Thank you! That'd be hugely helpful for us, especially since it makes it show on our dashboard that we have hundreds of thousands of "Errors" (most of which are actually just workflows). Makes it very hard to understand our system health.

unsync•7/3/25, 4:19 PM

We started on workflows and this puzzles me, if I have a long running workflow, I get close to zero observability of what happen inside my steps until the whole execution is done ?

martinhoest•7/3/25, 7:43 PM

I must be fooling about with Workflows and Observability - or is it normal that a failing step of a Workflow will not add meaningful logs to Observability?

The error here is thrown within

step.do

step.do

but it is nowhere to be found from the logs tab of the worker. I also cannot find anything on the Instance ID of the workflow invocation.

ddsgadget•7/4/25, 2:17 AM

Thank you! yeah, I understand the error has no impact on the actual workflow. But, it is really annoying to see the errors in the dashboard when there is no real workflow error.

Gabriel Francisco•7/4/25, 3:46 PM

is it possible to see the logs of a particular step? this seems basic but I can't find a specific filter for that

Gabriel Francisco•7/4/25, 4:37 PM

my workflows are going to some weird "Waiting" state, even without sleeps, I would like to see what is happening but can't find any logs

martinhoest•7/5/25, 6:45 AM

What's the expected output in logs if one Workflow triggers another Workflow, but the instance ID of the latter already exists?

Will I need to loop through all created instances from await this.env.WF_FILING_INGEST.createBatch(batchParams);await this.env.WF_FILING_INGEST.createBatch(batchParams); and call their status()status() function?

Or it might be better to check for existing instance before creating new?

related question, the step timeout is 10mins, is it wall time or compute time?

so there is a site of mine say abc.com now i m thinking to apply zero trust policies in it . so basically i want ki user should be able to access the auth page only via warp client and not by directly hitting the url on website.
how to achieve this ?/

Clarifying Maximum Workflow instance creation rateMaximum Workflow instance creation rate Limit

The createBatch documentation says

call to createBatch is treated the same as a call to create (for a single instance) and allows you to work within the instance creation limit.

Does this imply that when using createBatchcreateBatch , if you were to create 100 instances per batch (the maximum), that you could create 10,000 instances (100 per batch * 100 calls) per 10 seconds?

I understand there are other limits that might kick in (e.g. Maximum number of queued instances), but this example is meant to clarify the creation rate limit.

Frank•7/11/25, 4:03 PM

trying to move one of our cache gen into workflow

list active users
fetch data
store into r2

my initial thought is having a workflow just to fetch users, then it kicks off another workflow to fetch and cache data based on user id
or better to just have a single workflow?

Seeking advice here, i want to create scheduled workflows. I want to create periodic tasks (i.e. daily at 9am, 1st day monthly), and one-time tasks (date xx at yy time). These workflows are dynamically added by the user via an api request to the worker. I’m using Hono to handle routing.

Durable Object alarms are better suited for this

Yash Gupta•7/21/25, 9:29 AM

Has anyone tried to access steps/execution history for workflows from within their application?

It seems that the workers binding for workflows only gives present status and output, and while the API itself has steps history, it doesn't work for local development, making it hard to incorporate that as part of the solution.

Another option I've explored is manually intrumenting the step, waitForEvent and sleep methods, but it seems like redundant work (and possibly flaky)

alex (he/him)•7/22/25, 11:44 AM

I'm really having some issues with workflow creations

alex (he/him)•7/22/25, 11:44 AM

Already using createBatchcreateBatch and try to create ~650 instances all at the same time

alex (he/him)•7/22/25, 11:45 AM

That would be 7 calls with createBatchcreateBatch.. however I'm still seeing super long time until createBatchcreateBatch resolves as well as a lot of too many requeststoo many requests errors.

alex (he/him)•7/22/25, 11:45 AM

This is super hard to debug and annoying too.. why does even createBatchcreateBatch limits soo hard?

Bboop Durable Object alarms are better suited for this

Rahul gangotri•7/22/25, 1:09 PM

alarms will be expensive as it also charges on wall time, so if a task is taking longer to resolve or making call to external api is in place, then its going to cost for all that wait time.

alex (he/him)•7/22/25, 4:34 PM

I think what could work is use Cloudflare Queues and then consume settings to take batches of 100 each and use createBatchcreateBatch, but then we would end up with QUEUE A -> WORKFLOW A -> QUEUE B -> WORKFLOW BQUEUE A -> WORKFLOW A -> QUEUE B -> WORKFLOW B at which point I would argue, we can rely on Queues solely and not use Workflows at all.

alex (he/him)•7/22/25, 4:37 PM

So the fact that we also can't control concurrency on a per Workflow level means, that if you publish 600 Instances using createBatchcreateBatch to Workflow AWorkflow A and every instance uses createcreate to run Workflow BWorkflow B that will not work, because as soon as 101 or more of Workflow AWorkflow A run in parallel, we already hit the creation limit to create those "child" workflows
