I thought https://protomaps.com/blog/serverless-maps-now-open-source was interesting.

A web application with 50,000 map loads using the Google Maps API will cost $350 per month.

A similar amount of traffic running through a Protomaps CDN install on Cloudflare, with an average of 20 tiles per session, costs fifty cents in Cloudflare Workers request fees.

beelzabub•3/10/23, 5:35 PM

I thought range requests are generally cacheable, no? You might need to store the actual asset in cache once but after that cache.match will honor ranges? I forget the details though. CDN behavior is extremely complex and I don't pretend to know it outside of the specific slice of how I'm using it

I don't think so? I tried tailing the Function, and I'm getting

kian•3/10/23, 5:45 PM

Same-ish behaviour as the normal CDN, except that all happens transparently (it'll pull the full file and serve you the range, then serving other ranged reads from that full file)

Kkian `put` will want the full file but you can make ranged reads against `match`

beelzabub•3/10/23, 6:07 PM

Doing 1000 subrequests within the context of 1 request is going to be slow (like ~1.6s to actually make if it's all cache hits) and feels like a lot. Are you sure you're doing 1k or more subrequests within the context of a single incoming request?

Jjondon Yeah. For instance, a flight check with 250 itineraries could involve 1000 IATA ...

beelzabub•3/10/23, 6:28 PM

Instead of storing each IATA code as a separate value, have you considered just storing it as 1 giant bundle and just caching the data on first use? I imagine the data doesn't change and it's probably quite small right?

Bbeelzabub Instead of storing each IATA code as a separate value, have you considered just ...

beelzabub•3/10/23, 6:29 PM

Something like:

let IATA_LOOKUP
export default {
  async fetch(req, env) {
     if (IATA_LOOKUP === undefined) {
       IATA_LOOKUP = await env.KV.get('iata.json', { type: 'json' })
     }
     // process using IATA_LOOKUP
     return new Response(...)
  }
}

let IATA_LOOKUP
export default {
  async fetch(req, env) {
     if (IATA_LOOKUP === undefined) {
       IATA_LOOKUP = await env.KV.get('iata.json', { type: 'json' })
     }
     // process using IATA_LOOKUP
     return new Response(...)
  }
}

Bbeelzabub Something like: ``` let IATA_LOOKUP export default { async fetch(req, env) { ...

beelzabub•3/10/23, 6:31 PM

Whether or not that works depends on the size of the data of course. If the object size is closer to ~100 MiB, you might need to start chunking somehow (e.g.

iata-AtoD.json

iata-AtoD.json

iata-DtoH.json

iata-DtoH.json

, etc)

Jjondon Thank you for the suggestion.This seems like a great solution. It should be well...

beelzabub•3/10/23, 6:36 PM

I figured. I had a IATA lookup table in a recent project I was playing around with and I think the entire website was just over 1 MiB compressed. Would have bundled it directly into my worker to simplify things but I don't know if >1 MiB workers are supported yet

Unsmart•3/10/23, 6:36 PM

5 MiB paid plan

UUnsmart 5 MiB paid plan 🙂

beelzabub•3/10/23, 6:39 PM

Grrrr. Should have just tried it. That's what happens when you rely on information from 2 years ago. I actually helped plan the work needed to raise that limit. I just rolled off to start R2 before that work completed and I did a bad job of following up. Good to hear it's been raised

Kirk Ouimet•3/10/23, 11:58 PM

Hi team - is it possible to do a list operation on a KV and have it stop at a certain character? E.g. I have these entries

1 - key1/keyA
2 - key1/keyA/keyAA
3 - key1/keyA/keyAA/keyAAA

and I just want to list and get 1 and 2 but not 3

James•3/10/23, 11:59 PM

not to my knowledge

Kirk Ouimet•3/11/23, 12:01 AM

yeah kind of tricky trying to get a graph type situation going on using KV alone

beelzabub•3/11/23, 1:35 AM

I do want to get to make list operations more like R2, but I'm not sure we'll be able to do that this year.

beelzabub•3/11/23, 1:35 AM

Strong candidate for 2024 though.

beelzabub•3/11/23, 1:36 AM

I know that's not a great answer though in the short term.

There’s no way to do it from your worker today. I would imagine we’d unify it similar with how list works on R2

Cyb3r-Jak3•3/14/23, 5:35 PM

You are correct. The node library is very out of date. The last commit was a year ago and the last tag two years ago

beelzabub•3/14/23, 6:45 PM

Wow I didn't even realize that was a thing. I'll raise it internally to see what the plans are for that.

KKevH Is it recommended to just use the api directly for now?

Cyb3r-Jak3•3/14/23, 6:54 PM

Yeah. The go api is the most update if you know go

Cyb3r-Jak3•3/14/23, 6:55 PM

IIRC, there is a plan to auto generate clients once the shift to openapi is done. The node, python, and PHP libraries don’t receive a lot of love otherwise

I mean, I don’t think I can complain at all… :winks_in_green_cloud:
