Hey and congrats for GA

!
Is it possible to have an in-progress state that could be queried? In the case of an onboarding workflow, while we wait on a specific outside event, we can fetch the status of the workflow and some arbitrary data. Maybe similar to Temporal Query feature?

definitely a

await workflow.status()

successfully?

jcheese•4/8/25, 1:26 AM

hi guys - is there a way to repeat the workflow multiple times? for example, when i go through step 1 - 5, and if some condition isnt met, start again from step 1. sort of like a recursive function

gruntlord6•4/8/25, 2:51 AM

Is there plans to have a template like other workers as an example?

Suman!•4/8/25, 4:03 AM

Yep - It is a

WorkflowInstance

and I can call

await workflow.status()

await workflow.status()

. Getting issue only calling

sendEvent

sendEvent

TypeError: a.sendEvent is not a function

TypeError: a.sendEvent is not a function

and this occurs only on the production environment. Local works good.

Logging -

console.log({ status: (await workflow.status()).status, workflow: JSON.stringify(workflow) });

console.log({ status: (await workflow.status()).status, workflow: JSON.stringify(workflow) });

workflow = {"fetcher":{},"id":"dcd3c481-07d4-44ff-bcd5-94e2502bc6ff"}"

Maybe storing something in KV as part of a step with the key being the workflow id, and having the

function of the workflow/worker fetch it would work

Matt Silverlock•4/8/25, 12:41 PM

Can you describe a little more about what you're trying to do? Workflows are great for multi-step / async tasks, but aren't themselves a "task scheduler" - you can use Durable Object Alarms, the Agents SDK (and the scheduling API), or even Cron Triggers to schedule tasks - incl. Workflows.

cosbgn•4/8/25, 1:14 PM

Pretty much say my user has a workflow like:

Search for new concerts in Rome and email me if tickets are less than 50$

Search for new concerts in Rome and email me if tickets are less than 50$

run it
```
every 6 hours
```
```
every 6 hours
```

My current system works like this: I have a single CRON which runs every minute, queries the DB for pending jobs and runs them. This works but is not really scalable. I'm thinking how I could setup a system where the user defined cron interval would be the trigger. i.e. when the user saves the workflow I create a new cron/alter/workflow/whatever which takes care of this one.

Matt Silverlock•4/8/25, 1:37 PM

I'd consider using an Agent - e.g. an Agent for each user + the Agent schedules a ticket-search Workflow that runs the search + validates prices + reports back

Matt Silverlock•4/8/25, 1:39 PM

This isn't the same, but it's similar: each repo is associated with an Agent -> the Agent kicks a Workflow for each PR.

In your case, it's an Agent per user, and the Workflow is for a ticket-search (instead of a PR/code review):

cosbgn•4/8/25, 1:40 PM

Yeah I'm looking at the agents api

cosbgn•4/8/25, 1:40 PM

gruntlord6•4/8/25, 3:08 PM

workflows seem a lot more streamlined an maintainable then doing the tasks independently, especially if they involve multiple workers or services.

theres also some things unique like the r2 trigger that could be really usefull on its own

Hello, is there any way to start multiple different workflows in batch ( using only one request ) I know we can start multiple invocation of the same workflow using the createBatch but IDK about different ones

as in a workflow invoking another workflow?

Is workflows now out of beta? OK to use in production?

Somewhat related to the above, is logging from workflows captured in the worker logs?

I have this in

Jadugar_Jaggu•4/9/25, 4:49 PM

Hey, I think there might be a bug with Cloudflare Workers.
Whenever I update any binding (like a KV namespace) from the dashboard and deploy the changes, the binding for the Workflow gets removed automatically. This seems unintended and could cause issues during deployment.

Matt Silverlock•4/9/25, 5:20 PM

If you are mixing the dashboard + wrangler you can run into conditions like this - strongly recommend using one model to deploy. cc @Sid Chatterjee if we can make sure Workflows bindings stick here.

hey guys how do I reduce my storage metric in workflows? I see that I have over 5GB of storage used (!!) and I do not need this but I don't see any option to delete old instances or even configure the workflow API to set a smaller retention period. Any ideas?

ccarse•4/10/25, 3:12 AM

So I'm building a tool that runs a workflow when a file gets placed in an r2 bucket. All working well. I'm trying to build a dashboard to show the upload events, trigger retries, etc.. The problem I'm running into is that env.WORKFLOW.get(<instanceId>) doesn't work for me in dev. Is this intended?
