The worker is a member of the orchestra and uses hono to scale the hono.js prisma it has no more dependencies

Alex99like•3/31/25, 10:15 AM

could there be a problem that one of the databases starts to degrade and the query time increases in the worker crashes, or is it the worker's problem?

DaniFoldiOP•3/31/25, 10:17 AM

hmm, do you happen to be using prisma's driver adapters?

Alex99like•3/31/25, 10:18 AM

Yes, I use planetscale

DaniFoldiOP•3/31/25, 10:18 AM

we've also hit this issue, and so have many others, see: https://github.com/prisma/prisma/issues/25714

unfortunately, we ended up having to switch to drizzle which has worked perfectly from the first moment - so that's the only thing I can comfortably recommend

The problem occurs under heavy load when there is a simultaneous request for 500 records. The worker is supposed to fetch data from the primary database and move it to the D1 replica. This issue does not occur when requesting fewer than 500 records.

Alex99like•3/31/25, 10:22 AM

or maybe the problem is that I access one worker 500 requests at the same time through bindings, does it have limits?

DaniFoldiOP•4/1/25, 12:36 PM

I don't think there is a limit for that

DaniFoldiOP•4/1/25, 12:36 PM

likely it's just the prisma driver code leaking memory :/

DDaniFoldi I don't think there is a limit for that

Alex99like•4/2/25, 3:55 AM

I was able to solve this problem by making one large query to the database instead of 8 small ones.

Alex99like•4/2/25, 3:57 AM

I have another problem, some of the requests are crumbling, but everything is fine when I call them again.
Error:
The script will never generate a response.

How would i update the wragnler version on pages build? similar to node, i set it in env vars, but how abuot wrangler, its using 3.101 i need v4.

Vlad Lykhonis•4/8/25, 3:39 PM

Hi all. Does anyone know how to pass arguments to a user worker? I see a dispatcher has a way to allocate user worker with parameters. But if I just pass anything in there rather than empty object, I get a parameter not found in worker error. Another question would be how to access those parameters in user worker later upon fetch?

I am also using Hono as fetch/app. Regards.

DaniFoldiOP•4/8/25, 4:38 PM

Hey, if you're looking at the second argument of the dispatcher binding, that should just be an empty object - it's some internal thing apparently, which (in my opinion) should have never been exposed.

The way to pass custom arguments is to take advantage of RPC, which is supported by wfp. Your user worker can be an RPC entrypoint, just like your workers, and then you can pass in any arguments just like with normal bindings.

There's a special one for outbound workers, but that data isn't exposed to the user worker, as the goal of that is to pass trusted data around

DDaniFoldi Hey, if you're looking at the second argument of the dispatcher binding, that sh...

Vlad Lykhonis•4/8/25, 6:26 PM

Okay. Totally in agreement regarding args. Right now im already rebuilding requests coming to my worker and then passed to user worker. I guess another option would fit here adding custom headers as a json to pass some state.
I just wanted to make sure I’m not making some too stupid decisions here.
Thanks

Hard@Work•4/8/25, 10:31 PM

You do that yourself. If you are using the API, you need to bundle/minify/patch scripts yourself

AAnand ahhh okay.. So upload it as many files or one file?

Hard@Work•4/8/25, 10:59 PM

I would probably bundled it into a single file, unless you are using stuff like WASM

AAnand @Hard@Work sorry to at you. Is there an api channel that I can get help from?

Hard@Work•4/8/25, 11:12 PM

There are the SDK channels, but none for calling the API directly

Vlad Lykhonis•4/9/25, 6:56 AM

btw forgot to mention. Example of workers for platforms is from 2022 and it has a type for worker args, but it is also simply empty object. Maybe it is a feature work in progress, not sure if someone can shed some light on this.

Regardless, looks like rpc and/or mutation of request are at least 2 work around to pass args to user worker in the meantime.

Adnan A.•4/9/25, 7:21 AM

Hi, is it possible for a worker within Workers for Platforms to have its own rate limit binding?

Walshy•4/9/25, 9:46 AM

Of course. Each user worker can have its own bindings

Walshy•4/9/25, 9:46 AM

You can specify them in the upload metadata

Adnan A.•4/9/25, 3:23 PM

Thank you

Hi, is there any timeline/update on the pre-release

wrangler@dispatch-namespaces-dev

wrangler@dispatch-namespaces-dev

branch making it into main? It seems quite behind the latest wrangler and i'd like to use some of the cool new stuff

oli•4/9/25, 6:11 PM

just saw this - https://github.com/cloudflare/workers-sdk/pull/5622

seems a ways off, any alternate recommendations for running workers for platforms locally in the meantime? might just make my own hacky fork

You probably want to marke them as external.

That was the case before yeah

AAnand here are the build options. it looks slightly crazy!

Hard@Work•4/10/25, 11:49 PM

I don't think you necessarily need all of them, but its probably a good guide to start from

likely one of the packages is using wasm under the hood - can you share your list of dependencies?
