what does the workflow concurrency limit mean? does that mean that if I have 5k scheduled, 100 will be initally scheduled to run, and as they conplete,m ore will be scheduled?

AviOP•10/30/24, 11:28 PM

basically 100 max parallelism?

AviOP•10/30/24, 11:29 PM

my usecase is that i'd like to run code every night at midnight, and id love to NOT have to create a separate cloudflare worker with a scheduledscheduled handler for this

AviOP•10/30/24, 11:29 PM

just one instance of that code

AviOP•10/30/24, 11:29 PM

essentially a global singleton

Jacob•10/30/24, 11:29 PM

The same Worker can export both the scheduled handler and the Workflow

Jacob•10/30/24, 11:30 PM

So it can all be in one .ts file

JJacob The same Worker can export both the scheduled handler and the Workflow

AviOP•10/30/24, 11:30 PM

yeah, but that worker is actually just a DO stub wrapper

Jacob•10/30/24, 11:31 PM

wdym?

AviOP•10/30/24, 11:31 PM

i guess we could do it there though

JJacob wdym?

AviOP•10/30/24, 11:31 PM

i mean the "worker" is literally just the minimum boilerplate/wrapper to wrap a DO stub

AviOP•10/30/24, 11:31 PM

but that doesnt mean we cant add a cron scheduled handler to it

Jacob•10/30/24, 11:33 PM

Yeah I’d just put the scheduled handler in the same worker that you’re wanting to trigger Workflows from

Jacob•10/30/24, 11:39 PM

Another trick I’ve found with crons (in general) that hit external APIs is to not schedule right at the top of the hour - some APIs I’ve used can actually slow down a bit because of everyone’s crons hitting them at the exact same time

Can a workflow codebase co-exist inside a Pages repo?

wrangler will deploy those to different entities in Cloudflare, so it should not matter where they reside on your side.

fry69•10/31/24, 4:42 AM

You might face problems linking such a repo from the dashboard though, maybe it still works with custom build commands?

it looks like

It should be possible to use separate wrangler.tomlwrangler.toml files in separate directories and invoke wrangler separately in those directories with npm scripts.

fry69•10/31/24, 5:10 AM

Maybe even go full monorepo

AviOP•10/31/24, 5:10 AM

but how would those get deployed?

AviOP•10/31/24, 5:10 AM

i'd want them tied to the worker i'm deploying with the main wrangler.tomlwrangler.toml

AAvi but how would those get deployed?

fry69•10/31/24, 5:10 AM

To different Cloudflare names/entities?

AviOP•10/31/24, 5:11 AM

i'm not trying to change our deployed infra to workaround a wrangler bug lol

i'm just gonna comment one out at a time

DiamondDragon•10/31/24, 5:30 AM

ugh i spent like an hour today trying to figure out why i could get the worker server to start... added a 2nd test workflow to play around

AviOP•10/31/24, 5:33 AM

yeah it’s rough. imo they should have added a note in the changelog or something

DiamondDragon•10/31/24, 5:36 AM

is it possible to inspect a workflow triggered locally?

AviOP•10/31/24, 5:36 AM

i’d also love to know this

fry69•10/31/24, 6:00 AM

Running workflows will not get updated of course, only freshly instantiated workflows will run the new deployed version.

DiamondDragon•10/31/24, 6:28 AM

Not sure if this is silly - does it make ense to use a RPC service binding in a workflow/step? getting TypeError: Cannot read properties of undefined (reading 'TEST_SERVICE') TypeError: Cannot read properties of undefined (reading 'TEST_SERVICE') when just testing around

bkyerv•10/31/24, 6:46 AM

is workflows accessible/supported from inside pages functions?

bkyerv•10/31/24, 6:46 AM

I mean directly via env.[workflow_name] e.g. from astro project. i.e. not via network like fetch(...)

Advany•10/31/24, 9:07 AM

I can't seem to figure out, how do I limit the amount of instances per minute a workflow can ingest? I have browser rendering working inside of the workflows and I want to limit it to only do around 1 instance per 10 seconds orso

why then do they keep this in their docs. thank you for pionting it out though

Advany•10/31/24, 10:17 AM

yeah, there are also a couple of other things. I think it will get fixed soon (like the create locally needing an id)

itsmatteomanf•10/31/24, 11:51 AM

I see, thank you!

bkyerv•10/31/24, 11:55 AM

in general are there any materials that show cases of proven practices that work well with workflows? i.e. is it better to keep interaction with the db inside the workflow or outside of the workflow in the worker itself. or more generally what actions are better to perform inside workflow vs. inside a regular worker?

Advany•10/31/24, 12:02 PM

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

itsmatteomanf•10/31/24, 12:24 PM

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)

what does the workflow concurrency limit mean? does that mean that if I have 5k scheduled, 100 will
