Is this something we should consider transient and immediately retry?

Ooof2win2 the issue with queues is theres the subrequest limit of 50 reqs

oof2win2•4/20/24, 5:31 PM

i mean worst case i send data to a queue to be distributed to individual queues…. it sounds horrendous as i would be making my own pubsub system essentially but it would work

avsaase•4/20/24, 8:26 PM

We are also waiting for pubsub. It would make a lot of things much simpler.

Investigating. You shouldn't get that at all.

Elliot Hesp•4/22/24, 9:42 AM

Hi All,

We have a queue setup (one message per batch), where say 50 or so items are created every 60 seconds.

The handler for the queue simply sends a fetch request to an endpoint, and if the response is not a 200 we trigger an alert.

Every so often one of these fetch requests seems to hang (until the worker times out). We added in some abort controller logic to cancel the fetch after 5 seconds.

Interestingly, we actually see the request coming in to handle the healthcheck which resolves in way under the 5 seconds timeout.

Does anyone know why this might happen? I know there's a limit on concurrent fetch requests from a worker at once, but I'd have assumed each queue invocation is it's own and doesn't have this limit?

not yet - currently i retry a few times on the caller (worker) side, and then give up and send the message to a DO for sending later

sometimes, but not always, sending to the DO also fails (with something like Network connection lostNetwork connection lost) - which is troubling since that is now lost payload.

I'm pretty sure this is just a function of Queues still being beta, and cf will try to make sure that

.send

does whatever it needs to do in tough situations to retry under the hood if necessary (like saving to disk when the network is down and retrying later)

John SpurlockOP•4/29/24, 11:55 PM

there is no http api for sending messages other than using a worker: https://developers.cloudflare.com/queues/examples/publish-to-a-queue-over-http/

you could write a worker with multiple named queue bindings that sent the same input message to n queues using

Promise.allSettled

Promise.allSettled

inside the worker, for example

Is local dev possible with the producer in worker one and the consumer in worker two?

timmm•5/3/24, 2:21 AM

I'm using next-on-pages for worker one to produce the message and I'm not receiving it on worker two

timmm•5/3/24, 2:22 AM

Admittidely, this is the first time I've tried starting up two workers so maybe I'm not doing it right. But my understanding is you can start them both up and bindings should work

timmm•5/3/24, 2:29 AM

On nevermind! I see you can't have queues across workers atm in local dev

Praefe•5/3/24, 5:37 AM

When

wrangler deploy

wrangler deploy

ing multiple times quickly with queue config changes, the queue consumer config (and producer) page would crash with internal issues, and if I reaccessed it, the data hadn't been updated.

So the first time, it worked fine, but then the next times, while the command ran successfully, the web UI didn't reflect the config changes.

Praefe•5/3/24, 5:38 AM

Lead to my coworker thinking that the retry_delay option didn't work in wrangler.toml, but in reality, it wasn't being reflected in UI
