What db do most people use with a worker?

..gwapes What db do most people use with a worker?

Hard@Work•8/12/24, 1:13 PM

It depends on what kind of data you have, what performance you need, how many queries you expect, etc.

.gwapesOP•8/12/24, 1:13 PM

ig something that has decent performance but won't hurt the bank

Keep in mind that D1 doesn't need Hyperdrive.

Isaac McFadyen•8/12/24, 1:16 PM

You can still connect to D1 without Hyperdrive and it will be just as performant.

It should, though note:

Email Routing does not have advanced routing options. Characters such as + or ., which perform special actions in email providers like Gmail and Outlook, are currently treated as normal characters on custom addresses. More flexible routing options are in our roadmap.

Route pattern matching considers the entire request URL, including the query parameter string. Since route patterns may not contain query parameters, the only way to have a route pattern match URLs with query parameters is to terminate it with a wildcard, *.

Is there a way to change this behavior to ignore the query string?

Erisa•8/12/24, 10:29 PM

Erisa•8/12/24, 10:30 PM

if its just one path i'd make two routes, one

example.com/path

example.com/path

and another

example.com/path?*

example.com/path?*

Brett Willis•8/14/24, 2:19 AM

Needing some help, is there is no mechanism for handling the event that a client disconnects/cancels a request?
When implementing event streams (SSE), I need to do some cleanup when the client disconnects from the stream.
Currently, one of two things happen:
(1) The request will just end with no opportunity to clean up.
(2) I do some complex

ctx.waitUntil()

ctx.waitUntil()

with a promise that manually resolves when the stream closes, and now I can do cleanup within that promise, but now I have no way to know that the client has disconnected and

ctx.waitUntil()

ctx.waitUntil()

will just be aborted by the runtime 30s or so after the client disconnects.

The only way is to regularly test writing to the stream (e.g. a SSE

: comment

: comment

) to test if the client is alive so that I can cleanup before that 30s elapses... is that correct? Any way to know immediately when a client has disconnected?

Brett Willis•8/14/24, 2:42 AM

Furthermore, I think

await stream.write(...)

await stream.write(...)

rejects immediately if the client is disconnected, however if subclassing a

ReadableStream

ReadableStream

, then

controller.enqueue(...)

controller.enqueue(...)

does not throw and neither is

underlyingSource.cancel()

underlyingSource.cancel()

called when the client disconnects?

Stoke•8/14/24, 12:03 PM

Does anyone know of any kind of example on how to deploy PR environments with slug urls similar to how pages does it? using Pages, I can

wrangler pages deploy --branch=pr123

wrangler pages deploy --branch=pr123

and it will automatically wire the

preview

preview

environment with URL

pr123.mypage.pages.dev

pr123.mypage.pages.dev

. I'm struggling to do the same with a worker, because the environment and routes have to be specified in wrangler.toml. I'd be fine with deploying to the same

preview

preview

env (for the variables), but then I'd need the route with the slug (

pr123

pr123

) to be updated to always point to the correct deployment ID. There will be multiple PRs active at the same time. Thanks!

Hey, trying to optimise a worker that I have to use less memory (as we are seeing out of memory errors) by streaming responses from KV instead of pulling the entire 3MB value into memory. Seeing some huge performance issues after making these changes though, requests taking 25 seconds in our test environment, but locally this all run quickly. I was wondering how cloudflare workers scale when they get hit with a lot of concurrent requests to a single edge region. Also, there are limits on 6 external requests at once, including to R2 and KV, is that per request or per worker?

Zack•8/14/24, 4:02 PM

I see, that could explain the issues we're seeing then. Why may they share the same isolate when from the same device/client?

Zack•8/14/24, 4:03 PM

Debugging this is proving a huge pain, especially as I can't get performance metrics for the CPU based part of the functions

Hard@Work•8/14/24, 4:05 PM

Connection Affinity. Basically, when you make multiple requests to a Cloudflare-protected website, your browser(or other client) may store information about the connection(which server you are connected to), so that you continue to connect to the same server over multiple requests. If you make multiple requests to the same machine for a Worker then they share an isolate(unless it is overloaded, iirc)

Zack•8/14/24, 4:08 PM

We basically store 3MB "lookup tables" in KV, previously we pulled these into memory, but with high concurrent request count that causes out of memory issues. So we are trying to stream the lookup table and process them per entry so we only use 64KiB per request (for the buffer)

Zack•8/14/24, 4:08 PM

But while doing that I am seeing super weird behaviour like the R2 requests taking 10 seconds or even 25 seconds alone sometimes

Zack•8/14/24, 4:09 PM

Which is where my theories about contention came in

Zack•8/14/24, 4:09 PM

I'll try to get that debugging working remotely

HHard@Work DevTools might be of use here? https://developers.cloudflare.com/workers/testing...

Zack•8/14/24, 4:51 PM

Sorry, one more thing, the really odd behaviour is this

Zack•8/14/24, 4:51 PM

The requests all get stuck for a while, and then basically all come back at the same instant

Zack•8/14/24, 4:52 PM

Zack•8/14/24, 4:52 PM

That's the call to R2

Brett Willis•8/14/24, 10:15 PM

ReadableStreamBYOBReader.readAtLeast(minBytes, bufferArrayBufferView)

ReadableStreamBYOBReader.readAtLeast(minBytes, bufferArrayBufferView)

as per
https://developers.cloudflare.com/workers/runtime-apis/streams/readablestreambyobreader/#methods says:

Returns a promise with the next available chunk of data read into a passed-in buffer. The promise will not resolve until at least minBytes have been read.

What happens if the source stream ends with less than

minBytes

minBytes

available? A little bit of sanity would say that it would resolve with the buffer partially filled with the available bytes, rather than rejecting, but that contradicts the absolute statement "The promise will not resolve until at least minBytes have been read". Can someone confirm and perhaps update the docs?

Hello, I have a question about Workers pricing. There is a line written in the pricing for inter-worker sub-requests that they are not charged.

 Inbound requests to your Worker. Cloudflare does not bill for subrequests you make from your Worker.

 Inbound requests to your Worker. Cloudflare does not bill for subrequests you make from your Worker.

https://developers.cloudflare.com/workers/platform/pricing/
Just to make sure I understand, this means that if I make a request to a worker from a client and this worker needs to call two other workers in JsRPC, this will count as a single request (but will bill me for the execution time in ms on all the workers), right? Or have I misunderstood?
