So if I am reading this correctly, Hyperdrive needs a public domain for the tunnel, correct? You can't point Hyperdrive directly at the ArgoTunnel domain(I don't remember the exact domain name off the top of my head)

Like, where I give my Hyperdrive a Tunnel ID, then it connects directly, so that there is no outside evidence that I have a connection to my DB exposed

How does this impact performance?

AJR•9/26/24, 1:26 PM

In almost all scenarios it's going to be very comparable to current performance. I wouldn't reach for this to solve perf problems, but I wouldn't expect it to be slower than your current setup.

AJR•9/26/24, 1:27 PM

With (really) big bulk inserts you might see some slowdowns. Please let us know if you do, as that's something we would want to address.

AJR•9/26/24, 1:30 PM

I meant if you do try it and do see slowdowns. We know some folks do larger inserts, but we don't think it should move the needle much for those. It's just an area of interest.

Matt Silverlock•10/2/24, 10:22 AM

The connection string is unique to the Worker you call it in and can’t be used outside Hyperdrive or your account, so it can’t be leaked. cc @thomasgauvin for docs here.

AJR•10/2/24, 10:27 AM

What Matt said, the Hyperdrive ID and your connection string are not secrets. Also, if the underlying secrets (password/client secret) were leaked, those can be updated either via Wrangler or API, so you don't need to make a whole new Hyperdrive if it isn't convenient.

At some point it's probably easiest to make a new one for the new provider, and then just swap out the ID in wrangler.toml, yeah.

Michael H•10/3/24, 6:27 PM

Howdy! Is there any type of logging viewable for hyperdrive private database tunnels? I have a postgresql server that is connectable directly via ssh port forwarding, via the tunnel established for hyperdrive cloudflared access tcpcloudflared access tcp, and of course on the machine itself. However, running the recommended test code (const sql = postgres(env.XXXX.connectionString);const sql = postgres(env.XXXX.connectionString);) results in a connection timeout with no further info provided. Thanks!

Michael H•10/4/24, 3:44 PM

Yeah, that's the same issue to which I was referring in my thread yesterday (hyperdrive) - I was building a full-stack in Workers Pages and the local hyperdrive dev connection worked OK, but the hyperdrive private connection seemed to be unable to talk to the tunnel, timing out in the process. I had a very productive chat with @AJR, who is looking into the issue

AJR•10/4/24, 4:03 PM

May or may not be the same issue. Is the DO connection behind a tunnel? Or publicly accessible?

Nick•10/4/24, 6:01 PM

Is there a better channel for asking questions specific to Tunnels? I'm having a connectivity issue setting up my database, but believe I've isolated it to the Tunnel.

Nick•10/4/24, 6:09 PM

I followed the instructions at https://developers.cloudflare.com/hyperdrive/configuration/connect-to-private-database/ and wanted to test database connectivity, so I allowed myself through the Access Application, and am receiving connection timeout errors while trying to connect directly from pgAdmin.

I read about the logging there, and found that no logs were being generated by my connection attempts.

Okay. If you DM me your hyperdrive ID, I'll dig a bit when I'm back in office Monday and see what I can turn up

If hyperdrive is out of the equation it gets harder for me to help with that, I'm afraid. I'll ask internally on Monday and see if anyone on some of the other dev platform teams knows something about it

James Eastham•10/6/24, 8:54 PM

Hey everyone, cross post here from the Rust channel and wondering if anyone can help.

Is anyone else using Rust alongside a Postgres database with Hyperdrive? I'm getting some weird intermittent connection issues, that is like either the worker can't connect or is timing out. I'm wondering if it's something to do with this background work happening and the connection not quite being ready.

James Eastham•10/6/24, 8:54 PM

James Eastham•10/6/24, 8:54 PM

Additional context, when I run locally with a local database it works absolutely fine

James Eastham•10/6/24, 9:29 PM

Ok, so I figured this out and just following up here.

It's actually to do with using SQL prepared statements. There's a great write up here. If I switch all the queries to use query_typedquery_typed it works perfectly. If the folks building Exograph are around then thankyou

https://exograph.dev/blog/wasm-pg-explorations-2#hyperdrive-with-the-extended-query-protocol

AJR•10/6/24, 11:47 PM

Yes, the exograph folks are around here occasionally, and that's a good write-up. While we don't officially support extended protocol messages in tokio-postgres right now, their fork seems to work quite well for people.

Aviation•10/7/24, 11:29 PM

I noticed that Hyperdrive now supports prepared statements, but that the docs have not been updated to reflect this change.

I'm wondering if it now supports SETSET statements, too, but the docs just isn't up to date

Cloudflare Docs

How Hyperdrive works | Hyperdrive

AJR•10/8/24, 12:01 AM

No, the PREPARE keyword is still not supported I'm afraid. Named prepared statements at the protocol level are supported now. This was to support the default behavior of some key drivers in the ecosystem.

thomasgauvin•10/10/24, 10:32 AM

We documented how you can use Hyperdrive bindings from Pages here!

https://developers.cloudflare.com/pages/functions/bindings/#hyperdrive-configs

Note that you will need to use Postgres.js, and set Node.js compatibility using the following configurations in your wrangler.toml

compatibility_flags = [ "nodejs_compat" ]
compatibility_date = "2024-09-23"

compatibility_flags = [ "nodejs_compat" ]
compatibility_date = "2024-09-23"

(This was mentioned in a separate thread but raising this in the main channel so all can see!)

Nick•10/10/24, 4:05 PM

Does Hyperdrive produce error logs that are visible somewhere? All I'm seeing returned to my worker is "TypeError: Cannot redefine property: query", and nothing in the Tunnel logs.

AJR•10/10/24, 5:00 PM

That's a JS error, Hyperdrive isn't throwing that one.

AJR•10/10/24, 5:01 PM

Example: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Errors/Cant_redefine_property

The JavaScript exception "can't redefine non-configurable property" occurs when it was
attempted to redefine a property, but that property is non-configurable.

AJR•10/10/24, 5:02 PM

To answer the actual question, though, we return all errors from the origin server, plus selected Hyperdrive-specific errors, as Postgres errors to your PG client. The recommended path here is to handle errors from your driver, and either log or condition on them as needed. Logging them will have them populated with all the other Worker logs

bennycondon•10/11/24, 10:48 AM

Sorry if this is a naive question. I saw on How Hyperdrive works | Hyperdrive that SETSET statements aren't supported. In that case, how would I perform an UPDATEUPDATE statement without using a SETSET statement?
