every time I deploy my worker the kv bindings is removed from my worker. I tried:

wrangler deploy --keep-vars

wrangler deploy --keep-vars

keep_vars = true
kv_namespaces = [
    { binding = "XXXXX", id = "XXXXXXX" },
]

keep_vars = true
kv_namespaces = [
    { binding = "XXXXX", id = "XXXXXXX" },
]

Not sure if it would be a matter of getting credit, but more that you can't run your own models on Workers AI yet.

Does this apply if I have it at root but add a query string?

Also what do you mean by global scope being an issue?

Can the automatic running of cloudflare worker code while I'm typing be turned off? I can't work like this when I get basic auth popups every split second and I dont see the advantage of my worker constantly running on each keypress when I can use the Send button anytime I need to run

You may be able to disable it in the settings, but otherwise, you can develop locally and push

masd4•11/29/23, 8:14 AM

I dont see an option for this but I think I may have a workaround.. I have to cause a syntax error and then it doesnt run constantly

masd4•11/29/23, 8:14 AM

nevermind it still runs

Hi, I am having problem with r2 audio/video file uploaded via presigned URL (PutObjectCommand). It was being uploaded but when we are going to use it via signedUrl(GetObjectCommand) for transcription, file cannot be read for transcription. The get presigned and signed URL are generated through Workers. I tried to download it and played in media player, and still it was unable to play the file. Did I missed something in upload using presigned url ?

but when I upload the file directly in R2, then transcribed the file via signedUrl, the transcription service that we are using are successfully able to transcribed it

Hey,

I'm currently trying to minimize latency as much as possible. I am currently using Cloudflare hyperdrive with my postgres db + a cloudflare kv cache for my entries, but I am still getting around 100ms latency. Is there any way to reduce this further? I am just running a simple select query and my return size is about 4KB. I attached an image of what my route looks like, and an image of what the respective latency for each operation is. I also attached an image for my db middleware to allow me to use my db in ever call. I know this is not very effective, but almost all my routes use a DB call anyway. Or is there any way to reuse an existing connection?

Unsmart•11/29/23, 5:47 PM

I would remove the cache and remove the 2nd db connection that doesnt use hyperdrive and it should be faster

Unsmart•11/29/23, 5:50 PM

and if theres some reason you really dont want to use hyperdrive for a specific route I would make it where you return only the hyperdrive connection or only the direct connection instead of opening both

Zetax•11/29/23, 5:52 PM

Why remove the cache? It seems to be much faster. Just trying to understand

Unsmart•11/29/23, 5:52 PM

hyperdrive already adds a cache so that would just double cache now

UUnsmart hyperdrive already adds a cache so that would just double cache now

Zetax•11/29/23, 5:55 PM

True, but for some reason the Hyperdrive cache is way slower. It adds about 80ms of latency

Zetax•11/29/23, 6:09 PM

Would cloudflare D1 be better for my use case? I just want the lowest latency possible

Isaac McFadyen•11/29/23, 6:54 PM

D1 would be lower latency in the location where it's created, but it's also SQLite (not Postgres) so anything Postgres specific won't work with D1.

Deo Kumar•11/29/23, 8:12 PM

I am using photon-rs using WebAssembly, and the worker throws

Error 1102: Workers Resources Limit

Error 1102: Workers Resources Limit

, I think it's due to CPU time limit. How can I check the cpu time taken by a fetch handler?

Unsmart•11/29/23, 10:26 PM

There's no hard limits you can impose, setting up WAF rules to try and block any bot traffic and rate limiting rules to disallow spam would be things you can do to try and ensure expected usage levels.

Normally you could also setup notifications for when you reach a certain request amount but seems due to the billing changes recently made to workers you cannot do this yet with the updated billing model.

NuxtJS SSR worker, my code is fetching my dotnet endpoint in azure using a cloudflare origin certificate. I have strict TLS turned on and my nuxt worker is getting 522 errors on request to dotnet endpoint. Do i need to somehow get worker to do an origin pull? If i turn off strict TLS worker goes back to functional

Thanks! I’ll try to look at it

Will•11/30/23, 11:09 AM

Still a newbie with serverless concept

Will•11/30/23, 11:10 AM

Does each api call invoke a function and each invocation spawn a worker, is it still preferable to write async?

Will•11/30/23, 11:12 AM

And how about service which have to wait for user input, let’s say an otp service.

User hit api
Api send otp via sms
Api wait for 30 sec for user inputting otp

How does one design such service in serverless? I am open to any solution.

zegevlier•11/30/23, 11:21 AM

Each time a request is made to your worker, the fetch() function is ran with the request information. In workers, multiple requests can share the same isolate (the thing that actually runs the code). You should write workers using async because if you don't do that, you wont be able to do many operations, as they often require async.

I would re-frame the problem here as instead of having the server wait for the user to input the OTP, the server give the user a time limit of 30 seconds to enter the OTP. There are many ways you could do this. You could send the user a JWT that they need to send back that expires after 30 seconds, or you could store the login attempt in a datastore like #d1-beta or #durable-objects.

Will•11/30/23, 11:27 AM

Thanks! Now it’s more clear.

I just see durable object, it looks like redis cache

which I think suit the otp use case.

But the jwt method looks more interesting, how does it work? Isn’t jwt token is too long for otp which is usually only four to six digit?

Erisa•11/30/23, 11:28 AM

I believe whats being suggested is the user is presented with a jwt and then within 30 seconds they must return both the jwt and the totp code, which mitigates the need to maintain any state yourself

Will•11/30/23, 11:28 AM

Wow! That’s genius

Will•11/30/23, 11:29 AM

Will•11/30/23, 11:29 AM

zegevlier•11/30/23, 11:30 AM

I don't think that matters here? Why would you need secrecy for this?

zegevlier•11/30/23, 11:31 AM

oh like that, yea you shouldn't store the OTP in there. Good call, a JTW wouldn't work well here

zegevlier•11/30/23, 11:31 AM

Point still stands though, you just need something that encrypts the information stored

Will•11/30/23, 11:35 AM

This is so much to digest, but I think I get a glimpse of the concern

so basically, the user can give back the the jwt token without having to recieve the otp?
