yeah will remove some and troubleshoot a bit myself

Just wanted to see if someone had run into similar issues before.

how do workflow updates work?

Avi•10/27/24, 12:07 AM

like if i deploy a new version of the code

Avi•10/27/24, 2:13 AM

ah, i found a thread addressing my concerns here: workflows

Dmitry•10/27/24, 2:45 AM

Anyone try implementing workflows into a SvelteKit app yet?

Trying to figure out how to load a Workflow class in something other than the workflow-starter app (i.e -

src/index.ts

src/index.ts

file)

is it possible to define different workflows for different environments, like
env.Production
env.Production
vs
env.Preview
env.Preview
in
wrangler.toml
wrangler.toml
? it is!

Bind to a Workflow from your SvelteKit app and invoke it? The Workflow doesn’t have to be in the same script.

sdr•10/27/24, 11:05 PM

This error message is confusing to me, throwing a NonRetryableError means the error is handled by the CF workflows platform right?

The execution of the Workflow instance was terminated, as a step threw an NonRetryableError and it was not handled

I'd add a "[...] and it was not handled by user's Worklow code, so the Workflow failed.", that should explain it better.

All IDs are unique at the moment - why do you need ID reuse in workflows?

fry69•10/28/24, 10:14 AM

My guess would be e.g. automatic "Terminate if Running", restart a workflow with updated information and kill any running one? This can be done with other existing means of course if I understand the docs correctly, just not automatic.

You will not be able to create multiple Workflows with the same ID

Timo Reimann•10/28/24, 11:24 AM

Heya

quick question to confirm my understanding: do nested steps behave identical to non-nested ones with regards to cache usage after failures?

Specifically, if a nested step fails, would the cached results from all parent steps be reused? Or is the caching of parent steps tied to the success of the (most) inner step(s) somehow?

Seekerdasbatatas•10/28/24, 11:25 AM

You are only charged for CPU cycles not wall time

about the invocations, it depends on how you write your workflow (your retry policy, how much time do you sleep) but providing you don't wait for too long it should be 1 invocation

Are retries a separate invocation?

I’m wondering because if it is, then in some capacity, it encourages a dev to handle retries ourselves as much as possible instead of using the system

Based on your answer, it sounds like the answer is “sometimes”

Jani•10/28/24, 11:43 AM

Exactly - for interval based workflows this would be very useful. In some other cases we'd want to reuse only if workflow failed, using the same id (lets say some part of id is assembled by entity id - meaning 1:1 mapping to entity) but with updated data

minutes, it's long enough that if you need to wait for that time or higher it's actually good that you get another invocation ahhaha

That’s very helpful, thank you, since the main use case IMO is downstream api is overwhelmed. So a few minutes is probably most obvious use cases

from the last unit of work (last retry then)

jordanfinners•10/28/24, 12:03 PM

Hey, been using workflows over the weekend, it's pretty great! I have some feedback/questions please

The output that is displayed in the UI for each step is awesome. But is it possible to copy a non-truncated version of it? Also, would it be possible to mark some as secret so it's not available?

Where do the console logs go? It looks like they appear in whatever triggered the workflows but a little hard to tie it all together

Is there any advice for unit testing?

Is it possible to increase the size limit returned by each step?

Are there any limits to the code running as part of the workflows outside of a step?

Happy to go through any of this in more detail

DiamondDragon•10/28/24, 3:28 PM

If I need to fetch a list of 500 items and then loop over each item and do some additional fetching to transform the data, and then run another few steps inside each loop, this can be handled in workflows correct? And in this use case would it be ok to use a dynamic key inside the workflow name argument since the items id would be deterministic if the workflow needed to retry
