Thanks! We use Cloud SQL for two other projects; this is the first time we’re using it for something that runs outside of Google Cloud though.

I'm having trouble connecting to my supabase database wether I'm using a pooler connection or a direct connection via hyperdrive. The Hyperdrive binding is

and the pooler connection times out without ever connecting. Anyone know what might be going wrong?

Nope. Release rolling out right now to address some corner cases with bulk inserts and very large resultsets. But that wouldn't have been going as of 10 hours ago when you messaged.

What kind of weird behavior?

Just wondering if I'm doing any vendor lock-in here.

A

AJR•12/16/24, 7:55 PM

In terms of how you'd actually use them, if you wanted to port away, no not really. You have the option of designing your app more around cached result speed, and also you probably want to avoid transactions more than if you were using direct connections (though that's true with most any connection pooler so.. eh). Overall it should be very portable, as a part of the userbase for Hyperdrive is meant to be folks with pre-existing databases and apps trying to move onto Workers.

If you find cases where that isn't true, please do mention them here.

Where are you querying from, and where's your origin?

AJR•12/20/24, 2:01 PM

Caching enabled or disabled?

F

Focux•12/20/24, 2:01 PM

caching enabled

A

AJR•12/20/24, 2:06 PM

Try without smart placement and without caching, let me know how that looks? Smart placement doesn't always cooperate with caching products. Caching will also be apples-to-oranges with a serverless driver that can't do that.

We (well, @thomasgauvin did all the actual work) recently did a quick comparison of a bunch of those serverless drivers and by and large found performance very comparable with those settings off, maaaaybe a slight edge to Hyperdrive today. If you're seeing that kind of gap even with those settings off I'd be very curious to figure out why.

As we roll out improvements, though, they'll mostly be of the kinds that serverless drivers can't take advantage of. Things like pool placement, caching improvements, etc. If it's still comparable in 3 months I'll be pretty surprised.

F

Focux•12/20/24, 2:17 PM

With cache disabled and smart placement now, the query times are more similar; the neon serverless driver seems to be 10-20ms faster

A

AJR•12/20/24, 2:18 PM

Ok. That's within the ranges we were seeing. Thank you for checking.

Serveless drivers solve a lot of the same problems as Hyperdrive, in pretty different ways. At this time, we do expect perf to be comparable, though cache hits should obviously be faster today.

F

Focux•12/20/24, 2:19 PM

Yeah, that's the behavior I'm seeing. The average seems to be almost the same.

A

AJR•12/20/24, 2:19 PM

Hyperdrive with caching disabled does ok with smart placement, but it's not as good as it could be. We have another big architecture change in progress that will improve that compatibility a good deal.

F

Focux•12/20/24, 2:21 PM

So, correct me if I'm wrong, but right now, the upside of using Hyperdrive seems to be the caching layer, right?

A

AJR•12/20/24, 2:25 PM

Depends on your architecture and how widespread your userbase is.
Hyperdrive beats serverless drivers in the following ways today (again, this list is expected to grow in the near future, stay tuned):

caching layer, as you noted
automatic connection pooling, don't need to handle that yourself (not as big a deal if your service gives you one the same way)
uses portable drivers, don't have to build targeting only one origin service (e.g. neon, though we do love them)
uses CF network for a lot of the transit, which may be more reliable than the local public internet depending on where you are

F

Focux•12/20/24, 2:31 PM

Great work, it's 100% worth it using Hyperdrive today. I can't wait to see what you guys build next. I'm hoping to see MySQL support

. Although the node MySQL driver doesn't support Workers yet, haha

Yu•12/23/24, 4:12 PM

So how do I test and debug locally? Is there any good practice?

A

AJR•12/23/24, 4:16 PM

Couple options.

One is to have a local DB (I keep this alias in my bashrc:
```
docker run -d -e POSTGRES_PASSWORD=password -p 5433:5432 postgres:16 -c ssl=on -c ssl_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem -c ssl_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
```
docker run -d -e POSTGRES_PASSWORD=password -p 5433:5432 postgres:16 -c ssl=on -c ssl_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem -c ssl_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
```
docker run -d -e POSTGRES_PASSWORD=password -p 5433:5432 postgres:16 -c ssl=on -c ssl_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem -c ssl_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
```
docker run -d -e POSTGRES_PASSWORD=password -p 5433:5432 postgres:16 -c ssl=on -c ssl_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem -c ssl_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
)
Use
```
wrangler dev --remote
```
```
wrangler dev --remote
```
which spawns an ephemeral Worker and will behave like a normal Worker. Still wants a
```
localConnectionString
```
localConnectionString
```
localConnectionString
```
localConnectionString
but will use the Hyperdrive binding you give it instead.
Use a remote DB that allows connections with
```
sslmode=disable
```
sslmode=disable
```
sslmode=disable
```
sslmode=disable
(this is probably the hardest to mange given I don't think Supabase supports that)

Y

I have tried the third method, but supabase does not support it.

I'm trying to make hyperdrive work in a svelte-kit project that uses drizzle. All the examples of hyperdrive usage I could find get

env

env

in the request, but in my project drizzle configuration is defined in a separate file:

const client = postgres(process.env.db || DATABASE_URL, {
  ssl: DATABASE_SSL === 'true',
  prepare: false
});

export const db = drizzle(client, { schema });

const client = postgres(process.env.db || DATABASE_URL, {
  ssl: DATABASE_SSL === 'true',
  prepare: false
});

export const db = drizzle(client, { schema });

const client = postgres(process.env.db || DATABASE_URL, {

export const db = drizzle(client, { schema });

const client = postgres(process.env.db || DATABASE_URL, {
  ssl: DATABASE_SSL === 'true',
  prepare: false
});

export const db = drizzle(client, { schema });

I tried to use process.env, but got no luck here. Can anyone please suggest the proper way to pass the hyperdrive url?
