Beny•4/23/24, 6:45 PM

You asked this one before, and the answer is still the same unfortunately.
The issue is that the API to create a consumer on a queue doesn't support referencing to dispatch namespace workers. Consumers are configured on the queue rather than the worker.
The only way for now is to create a regular worker that dispatches it to the user worker. You can use RPC to pass it to a handler other than fetch

I assume you mean cron triggers? I would assume they do but have not tested myself.

U

And if by scheduling you meant very specific time instead then you can use durable objects to make alarms to support invoking at a specific time

DORSHT•4/26/24, 8:20 AM

Hey, beginner question that maybe someone here can help me out with.
I'm going through the basic "Getting Started" docs of WFP, got a namespace, a user worker and a dispatcher.
So far everything works. Now, i've updated my dispatcher to be a dynamic dispatcher which by the docs is supposed to receive calls to

<USER_WORKER_NAME>.<MY-DOMAIN>.com/*

<USER_WORKER_NAME>.<MY-DOMAIN>.com/*

<USER_WORKER_NAME>.<MY-DOMAIN>.com/*

<USER_WORKER_NAME>.<MY-DOMAIN>.com/* and from there extract the user worker name and call it. But, calls i'm making to

*.<MY-DOMAIN>.com

*.<MY-DOMAIN>.com

*.<MY-DOMAIN>.com

*.<MY-DOMAIN>.com are not getting to my dispatcher worker (only calls to

<MY-DOMAIN>.com

<MY-DOMAIN>.com

<MY-DOMAIN>.com

<MY-DOMAIN>.com do).

It doesn't say in this part of the docs how i should have configured my dispatcher's domains / routes for this to work, can someone help me understand what i'm missing?
Thanks.

Beny•4/26/24, 2:25 PM

Which route did you put on the dispatch worker? Should be something like

*.mydomain.com/*

*.mydomain.com/*

*.mydomain.com/*

*.mydomain.com/*

BBeny Well it's meant to work but it has an `workers.api.error.unknown` error

howdy folks, sorry for the delay, but this error when deleting secrets from namespaced workers should be fixed

Beny•5/4/24, 6:39 PM

When using #rate-limiting-beta with Workers for Platforms is there anything special implemented for the

namespace_id

namespace_id

namespace_id

namespace_id or is that ID still shared among all scripts?

U

Unsmart•5/5/24, 2:31 AM

if you use the same id it would use the same namespace if thats what you mean

UUnsmart if you use the same id it would use the same namespace if thats what you mean

B

Beny•5/5/24, 6:47 PM

Yeah, that's how I imagine it works. Was just wondering if there had been any considerations for Workers for Platforms, such as them being scoped to each dispatch namespace.
It might become a challenge to maintain a database of namespace ids assigned to each user (to prevent them affecting each other) when there are a lot of workers across various dispatch namespaces and deployment systems.
I'm sure it wouldn't be an issue at the moment with the maximum rate limit period being 60 seconds, but that's sure to increase in the future and might affect other workers if they both end up using the same namespace id.
Perhaps an option that disables it being scoped across all workers would be useful in situations like this, where that behaviour becomes an obstacle rather than something useful.

U

Unsmart•5/5/24, 7:09 PM

Not sure why it would be hard to maintain a db?

UUnsmart Not sure why it would be hard to maintain a db?

B

Beny•5/5/24, 7:14 PM

Well in my situation that would involve creating a central database among 3 different deployment systems, with clashing user ids & script names. Of couse it is achievable, but not an easy task.

B

Beny•5/5/24, 7:18 PM

All that work could be avoided by a single additional option in the binding

U

Unsmart•5/5/24, 7:26 PM

I highly doubt they would do that as it completely defeats the point of namespaces

B

Beny•5/5/24, 7:29 PM

Hmm, what if namespace ids could be any string and were converted to a number behind the scenes?
If we could use a dynamic string that would solve everything, such as

namespace_id = "stores/[user-id]/1"

namespace_id = "stores/[user-id]/1"

Knowing which script correlates to which namespace number is the tricky bit

B

Beny•5/5/24, 7:48 PM

Yeah agreed, the option to disable it would remove the purpose of namespaces, but that might be useful for some people.
Instead of being at the account level, if they were at the dispatch namespace level for user workers this would also be helpful. It would be easier to maintain a database of ids for user workers in each dispatch namespace than across the whole account.
The option to set a scope level, like account/dispatch_namespace/self might be better

W

Walshy•5/5/24, 7:54 PM

A namespace is expected to contains thousands or millions of scripts from different customers so I don't think that'll add much more than account level

W

Walshy•5/5/24, 7:55 PM

but yes, I understand the need here. The rate limiting binding is a bit special here in how it works. cc: @tanushree │ Workers PM (for Monday)

Beny•5/6/24, 10:27 PM

The API for that doesn't work in WFP. The recommended ways to debug a user worker are with Workers Logpush and Trace Workers.
There was a Google Docs we all got shared in the beta with a walkthrough on how to do it, but some of that information hasn't been added to the Cloudflare site yet. It's not marked as confidential so I assume I can share it here.
The "Trace Workers" in there look identical to Tail Workers, perhaps they are the same thing (renamed from trace to tail?)
