I do need to read. In each request, I'm essentially checking if the value has reached a certain number. It doesn't need to be strictly consistent so I can wait for the bulk process and be off by a few.

Hello, I’m Allie!OP•3/1/24, 6:34 AM

So it is an increment, plus a read? What you could do is push to AE, then have a cron trigger that checks whether it went over, and pushes that state to KV

H

Hello, I’m Allie!OP•3/1/24, 6:34 AM

This has the added benefit of being comparatively scalable

H

Hello, I’m Allie!OP•3/1/24, 6:34 AM

That one isn’t an imposed limit iirc, but just with how fast D1 can process a query, coupled with the fact that it isn’t multithreaded

I don't believe I currently have access to DO on free tier. I imagine I'll inevitably require paid tier but right now I'm just building PoCs so the gated services kinda make that hard.

I wish the limits and pricing for every service were side by side. Maybe I'll make a table for that just to keep my sanity.

Trade off is more expensive for less latency and faster consistency, right?

Hello, I’m Allie!OP•3/1/24, 6:46 AM

D1, since it is a single isolate somewhere, can only handle so many requests

Q

quisi.do•3/1/24, 6:46 AM

It's in us east IIRC

Qquisi.do It's in us east IIRC

H

Hello, I’m Allie!OP•3/1/24, 6:47 AM

I meant more, because it is only one isolate, it can at best handle a few thousand rps(and that is without all of the SQLite machinery running every query)

H

Hello, I’m Allie!OP•3/1/24, 6:48 AM

And the values aren’t cached either, so every request is backhauled to the database. You can remedy that yourself tho

H

Hello, I’m Allie!OP•3/1/24, 6:49 AM

This would also be fixed by read replicas, but those don’t exist yet

Cloudflare Worker is waiting for the whole response before streaming the output to the client, which defeats the entire point of streaming. I don't know what I am doing wrong.

router.post("/v1/streaming", async (request, { OPENAI_API }) => {
    let { readable, writable } = new TransformStream();
    const client = new ChatOpenAI({
      openAIApiKey: OPENAI_API,
    });

    const stream = await client.stream(
      "Write a 2 sentence poem about a sunset."
    );
    let writer = writable.getWriter();
    const textEncoder = new TextEncoder();

    for await (const part of stream) {
      if (part.content.length) {
        // Assuming part.content is a string containing the text
        const words = part.content.split(" "); // Split the text into words
        for (const word of words) {
          const sseFormattedData = `data: ${word}\n\n`; // Format each word as SSE
          await writer.write(textEncoder.encode(sseFormattedData));
          console.log("🚀 - forawait - sseFormattedData:", sseFormattedData);
          await new Promise((r) => setTimeout(r, 1000)); // Wait for 1 second before sending the next word
        }
      }
    }

    writer.close();

Is it possible to have multiple workers run on the same custom domain, or do I need to have one worker that handles routes for the entire domain? It seems when I try to deploy a second worker, it wants to link the new worker the the already existing custom domain and remove it from the old worker. If this is the case, what is the point of the Workers Routes section under the domain?

I know the most specific route wins but not sure how it would be calculated. I can play around with it later today and see

K

kian•3/1/24, 4:13 PM

I don't think you can even have infix wildcards can you?

C

Chaika•3/1/24, 4:14 PM

There's a ton of docs on routes here: https://developers.cloudflare.com/workers/configuration/routing/routes/#validity

C

Chaika•3/1/24, 4:15 PM

Route patterns may not contain infix wildcards or query parameters. For example, neither
example.com/*.jpg
example.com/*.jpg
example.com/*.jpg
example.com/*.jpg nor
example.com/?foo=*
example.com/?foo=*
example.com/?foo=*
example.com/?foo=* are valid route patterns.
When more than one route pattern could match a request URL, the most specific route pattern wins. For example, the pattern
www.example.com/*
www.example.com/*
www.example.com/*
www.example.com/* would take precedence over
*.example.com/*
*.example.com/*
*.example.com/*
*.example.com/* when matching a request for
https://www.example.com/
https://www.example.com/
https://www.example.com/
https://www.example.com/. The pattern
example.com/hello/*
example.com/hello/*
example.com/hello/*
example.com/hello/* would take precedence over
example.com/*
example.com/*
example.com/*
example.com/* when matching a request for example.com/hello/world.

I would read this: How are CPU limits enforced in the free tier?

C

Chaika•3/1/24, 5:14 PM

tldr being you don't have enough requests to trigger it/the limit is loose and you get an initial quota

C

Chaika•3/1/24, 5:15 PM

if you get enough requests, and those requests all exceed the time, you'd start seeing errors

Well, if they are just incrementing, then they don’t actually need to read, just write
