Is it possible to have workflows defined in a pages worker?

Ttornado Is it possible to have workflows defined in a pages worker?

DanGamble•10/26/24, 7:24 AM

No, they're just workers at the moment. This is just my opinion but they likely will stay that way with the introduction of worker assets (https://developers.cloudflare.com/workers/static-assets/)

With a nested step, if a nested step fails or needs to be retried, does that mean the outer step also fails/retries?

DanGamble•10/26/24, 9:13 AM

Also, love the "Rules of Workflows" piece of the documentation https://developers.cloudflare.com/workflows/build/rules-of-workflows/. Definitely helps understand things a lot more. Would love to see this kind of thing on all products. Especially DO's

Cloudflare Docs

Rules of Workflows | Cloudflare Workflows docs

A Workflow contains one or more steps. Each step is a self-contained, individually retriable component of a Workflow. Steps may emit (optional) state that allows a Workflow to persist and continue from that step, even if a Workflow fails due to a network or infrastructure issue.

Workflows work fine for me in dev mode but deployed seem to never finish, eventhough the last expected step finished succesfully

makisuo•10/26/24, 10:09 PM

I am using EffectTS and for that reason am wrapping step.do to use it better with effect but dont really see how that could be the issue:

export const stepEffect = <A, E>(
    step: { do: (name: string, fn: () => Promise<any>) => Promise<any> },
    stepName: string,
    effectFn: Effect.Effect<A, E, never>,
): Effect.Effect<A, E, never> => {
    return Effect.promise(() => executeRpcWithCleanup(() => step.do(stepName, async () => Effect.runPromise(effectFn))))
}

export const stepEffect = <A, E>(
    step: { do: (name: string, fn: () => Promise<any>) => Promise<any> },
    stepName: string,

): Effect.Effect<A, E, never> => {

}

Your first step for troubleshooting should probably be to see if it works without EffectTS. I don't think anyone here uses EffectTS and so the amount of help we can give when that's involved is going to be limited

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

sdrOP•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

itsmatteomanf•10/27/24, 11:11 PM

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

I.e. separate steps don’t count as a separate invocation? What about retries? Are they a separate invocation etc

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

MissS•10/28/24, 11:43 AM

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”
