that was quick

looking forward to it! Good idea to keep the step outputs available for debugging locally

Avi•12/19/24, 3:49 AM

seems like there might be some sort of outage? when i create new workflows, they have no steps, and when I try to pause or terminate the instances in the dashboard, those API calls return 500 errors like:

{
  "success": false,
  "messages": [],
  "errors": [
    {
      "code": 10001,
      "message": "workflows.api.error.internal_server"
    }
  ],
  "result": null
}

how long is "eventually"? I'm seeing many instances, whose first step is a simple await step.sleep('wait 24 hours', '24 hours')await step.sleep('wait 24 hours', '24 hours'), which have been stuck in the "running" phase for many hours (30+)

Is there a way to delete workflows on our accounts? I can’t seem to find it either in the dashboard or api

Fernando Barroso•12/20/24, 10:28 PM

Oops! What happens if you delete the worker bound to a workflow? Can that workflow still be used by another worker?

hkdobrev•12/21/24, 6:45 AM

I'm using workflows and I really like the built-in design to retry individual steps, very much like a multi-queue solution for each step.

However, I'm also using queues to trigger N instances of the workflow as I want to space out some external calls, so I'm using delay with the queue.
But I'd very much like the workflow to receive the original batch.
This would allow for a much more robust acknowledgement and retry mechanism. If the workflow has access to the JS API of the queue batch, it will be able to control acknowledgment of the message. By retrying the queue message, it will be able to revert back executed steps by retrying the queue message and triggering a new workfow instance resetting the state.
The step sleep is not enough for that.

Currently, I need to resort to acknowledging all messages in the queue batch as soon as the workflow is triggered regarless if it's successful.

D Trombett•12/21/24, 11:08 AM

Assuming that I have a workflow which at the end returns something, can I later retrieve that value using env.WORKFLOW.get(id).status().outputenv.WORKFLOW.get(id).status().output (something like a sort of kv?) or is it something one shouldn't rely on (e.g. expires after some time)?

D Trombett•12/21/24, 11:35 AM

Ah, I guess this is part of the following limit:

Retention limit for completed Workflow state: 3 days; 30 days

Ashley•12/21/24, 6:11 PM

Just as an FYI, I think there's some out of date info in the docs referring to event.paramsevent.params (e.g. https://developers.cloudflare.com/workflows/get-started/guide/) whereas I now think it's event.payloadevent.payload (changing this fixed it for me so guessing event.params was old?)

Warren•12/22/24, 4:35 AM

Asking a question re the

Serialized RPC arguments or return values are limited to 1MiB

Serialized RPC arguments or return values are limited to 1MiB

error

the limits:

maximum persisted state per step is 1MiB
Workers return value can only be 1MiB

as such, what I'm trying to do is to ensure that the work done in step in is smaller than the 1MiB limit before returning it.

I am using this to get the size of the return value

export function getApproximateSizeInBytes(obj: unknown) {
  return new TextEncoder().encode(JSON.stringify(obj)).length;
}

export function getApproximateSizeInBytes(obj: unknown) {
  return new TextEncoder().encode(JSON.stringify(obj)).length;
}

however, I notice that the value returned and the actual value shown when an error is thrown can be quite different.

how can I reliably check what is the size of a return value before returning it?

(guess this is not specific to Workflows, but it's relevant in this context because a workaround I've seen is to use ReadableStream, but that wouldn't work because of the max persisted state per step limit)

oof2win2•12/26/24, 3:01 PM

is it possible to increase the number of maximum outbound requests, higher than 1k? splitting the workflow into multiple executions probably is a possibility but it seems kinda weird as a limit

yzziK•12/26/24, 9:43 PM

agreed ^

yzziK•12/27/24, 1:15 PM

hi will the step_namestep_name be added anywhere in future in status ?
like the cloudflare dashboard shows the steps status so its easier to track on which step is currently processing.

i return step_namestep_name along with the data as a workaround

we have workflows which have a total execution time of less than 10 m and want to be able to run 50K per minute and it is not a constant rate.

yes 900/s or more concurrent WF, right now we are using the queue and are event based, liked the workflow model which fits our use case, we want to have multiple campaign workflows which would create multiple subscribers workflow. subscribe workflow will perform bunch steps and send out the content

Matt Silverlock•12/28/24, 5:43 PM

We’re still early-ish in the beta so won’t be 900-1000+ concurrent overnight. Recommend using a Queue here - even at scale, a Queue is going to give you the mechanisms to manage the backlog

tadhglewis•12/31/24, 12:02 AM

It doesn't seem like a good fit to me. You're trying to do asynchronous work in a synchronous flow. Why not just do your workflow logic in the hono API?

tadhglewis•12/31/24, 12:04 AM

The entire thing with Workflows is it doesn't provide guarantees on when it will finish or how quickly. You would run into issues with connection timeouts etc if you try to keep an API connection open

tadhglewis•12/31/24, 12:05 AM

It's hard without knowledge of what you're doing but a common standard if you need to notify a consumer once async work is done is by sending them a webhook
