Matt Silverlock•10/2/23, 9:48 AM

Not yet - we’re focused on making Workers fast - as Worker’s distributed model + expensive database connection setup weren’t a good combination previously. Where is your app running if not Workers?

EC2 server with pm2, a good old nodejs app with AdonisJS as a framework and an Aurora database

kian•10/2/23, 9:51 AM

Will Hyperdrive (and I guess the TCP API in general) be affected by Aegis' dedicated egress IP, or is that use-case going to be covered by the Tunnel integration when that lands?

Matt Silverlock•10/2/23, 10:19 AM

Interesting: candidly, I would be surprised if Hyperdrive is faster here. Long running EC2 VM and Aurora - Hyperdrive’s caching will be nice in some cases but for AWS-to-AWS you’re going to pay egress + latency to get to us. Would love to say we are a win there but if this is same region…

This - it’s all dependent on plugging into Magic WAN/Tunnel infrastructure (same thing).

Zak @ insertchat.com•10/2/23, 10:26 AM

@Matt Thanks for the answer, the thing is I want to switch to Vectorize at some point, will there be a point when it's open to non workers users? Or do I need to find a way to push data to Vectorize using my node app, then call a CF Worker to get my vectors and process them on my node app?

Matt Silverlock•10/2/23, 10:29 AM

Vectorize and Hyperdrive are entirely separate things. You can use Vectorize through a Worker to expose your own API, or use Vectorize’ own API.

@Matt I understand, I was just hoping for a way to get the full benefits of CF workers without having to rewrite all the code. I guess I will add moving to Workers to the roadmap x)

By the way, Vectorize is built on top of what? I can't find the info or any benchmark

Matt Silverlock•10/2/23, 10:32 AM

I would (genuinely) LOVE to understand how you came to understand that you need both - you can’t really benefit from Workers if your app is still directly in EC2. Not sure what architecture you’re thinking here.

Moving your “middleware” (all your database interop code) to Workers can be a good first step though.

I originally thought I was going mad after using a non-pooled connection string from Neon in Hyperdrive before I realised that's one of the main points of Hyperdrive, connection pooling. meowpuffydizzy

kian•10/2/23, 2:55 PM

It'd be nice if Wrangler made a warning/error when you use local development w/ Hyperdrive bindings. You do get a warning that they're experimental, and that callout is made in the docs, but it's an easy issue to hit with local being the default.

kian•10/2/23, 2:55 PM

Something similar to Queues, which tells you that they're not available in remote mode.

Using Cloudflare Hyperdrive with tokio-postgres in Workers

Cloudflare recently announced their query caching & connection pooling solution for databases in Workers, Hyperdrive.

Whilst there's plenty of examples of using Hyperdrive with libraries like pg in the documentation, someone in the Cloudflare Developers Discord asked about usability with Rust Workers.

There are examples for using tokio-postgre...

kian•10/3/23, 3:57 PM

I think requiring an explicit port number in the connection string is a bit odd and non-standard, though. Could you default it to 5432 like everyone else?

There's an open PR which will do that when merged.

kian•10/3/23, 4:05 PM

My suspicion is that the id can only be used from within my own account, and so it isn't?

Yep.

Unsmart•10/3/23, 4:06 PM

Quick questions - in the demo, a new connection is opened for each request (if I'm right). Won't this overload the PostgreSQL server when there're for example thousands of requests each second?

Also, I've created a Hyperdrive Id using wrangler. Should the dashboard in cloudflare change, or will it stay like this?

And last - in local development, I can't access the database (works in prod after wrangler deploy). I'm receiving the following error:

Cannot read properties of undefined (reading 'connectionString')

Cannot read properties of undefined (reading 'connectionString')

Do I need to add any parameters to the dev start up?

Thank you!

Can hyperdrive be set up for local development to only be used when I run `wrangler dev`? I want to
