I made a workaround. Add the workflow items to a d1. Then a do sends it every 10 seconds to the workflow. Dripping it into it.

Would be great if we could just add that on step level of workflow level

The less work each step makes, the better. Each step will be retried, persisting results from other steps, but not variables outside of those (so the variable assigned from a step return is maintained, a random variable is not)

I

itsmatteomanf•10/31/24, 12:24 PM

Do a db step, do a processing step (or even a per item processing, if it’s a loop and it’s not too long to go over the step limit)

I

itsmatteomanf•10/31/24, 12:25 PM

Do consider that you can nest steps, too. If you were to need that.

Isn’t the step limit 250? So I have a step that return an object of 500 items and need to loop over each item to make another external api call and do further processing, I can’t have a nested step inside the for loop to process each item? Since it sounds like I’d hit the step limit

itsmatteomanf•10/31/24, 2:56 PM

Exactly, yes. The limit is 255 steps.

I

itsmatteomanf•10/31/24, 2:56 PM

Do remember that you still have the 1k subrequest limit that applies and that retries will be counted against this limit.

hi, trying to add workflows like this in wrangler.toml

workflows = [
  {name = "first-workflow", class_name = "FirstWorkflow", binding = "WORKFLOW_ONE"},
  {name = "second-workflow", class_name = "SecondWorkflow", binding = "WORKFLOW_TWO"}
]

workflows = [
  {name = "first-workflow", class_name = "FirstWorkflow", binding = "WORKFLOW_ONE"},
  {name = "second-workflow", class_name = "SecondWorkflow", binding = "WORKFLOW_TWO"}
]

workflows = [
  {name = "first-workflow", class_name = "FirstWorkflow", binding = "WORKFLOW_ONE"},
  {name = "second-workflow", class_name = "SecondWorkflow", binding = "WORKFLOW_TWO"}
]

workflows = [
  {name = "first-workflow", class_name = "FirstWorkflow", binding = "WORKFLOW_ONE"},
  {name = "second-workflow", class_name = "SecondWorkflow", binding = "WORKFLOW_TWO"}

just to clarify, it means that if you have 5k queued (scheduled workflows pass to queued, once they are intended to be run), 100 will be initially instructed to run, and as they complete, more will run?

Hi

. Does anyone have a demo Remix repo I could learn from? (using remix-run/remix/templates/cloudflare-workers)

I have tried following @Craig's "punderful-workflows" example, and kept it very simple in the wrangler and the "main" JS file (following his example, but in a Remix repo)....

But no matter what I do, I always come up against this error....

You can’t deploy a Workflow as part of a Pages app (which is likely what the default Remix build is trying to do).

Deploy the Workflow separately (as a Worker) and bind to it from your Pages app / call it over HTTP.

I’m exploring Cloudflare Workflows to streamline email notifications for parents on our e-learning platform. Our goal is to notify parents based on specific events they’ve subscribed to, like when a student completes a quiz, finishes a topic, or needs a daily/weekly family summary. We want to set these notifications to trigger at defined times, tailored to each user’s preferences. If anyone has insights or tips on setting up these kinds of recurring notifications effectively, I’d love to hear them!

Thanks in advance for your help!
