Ddarkpool is it possible to use google spanner with hyperdrive?

AJR•1/29/25, 9:45 PM

I don't believe anyone is doing that, no. We haven't tested it, though some brief googling does show spanner has a "postgres-compatible" interface, which I hadn't realized. Might be worth us taking a look, at some point.

Details on which database engines and/or specific database providers are supported are detailed in the following table.

Thanks for the reply. Spanner Graph is in preview right now and looks pretty interesting plus recent support for proto data types. Although it seems new graph capabilities are only available in GoogleSQL interface not PG atm.

There's Amazon Aurora DSQL too

dave•1/30/25, 5:06 AM

That said, I found the limitations too hard to work with.. Takes away a lot of the things I love about using PostgreSQL (making sure I don't shoot myself in the foot).

AWS RDS Aurora Serverless v2 is my goto. Scales to zero as well, which is very nice for dev instances

Hello,
Currently i'm using hyperdrive with direct connection to supabase.

They do actually work over Hyperdrive, that one we checked. The needing to refresh an IAM token every 7 days isn't great though, we'd need to build some AWS IAM integrations to automate that to really call them "supported", imo.

dave•1/30/25, 5:50 PM

That's pretty easy to do. I already wrote a function for refreshing the IAM token, so I'd just need to use one of these endpoints to update it every 24 hours (to be safe to avoid long lasting connections from expiring).

PATCH vs PUT. PATCH will only update the things that were changed. PUT will update/overwrite the whole config, and trigger revalidation.

More practically, it's because PATCH in terraform is a pain so we felt it would be most efficient to just have both.

dave•1/30/25, 5:52 PM

ah, so I'd want to use PATCH here?

AJR•1/30/25, 5:54 PM

IIRC refreshing the token gives you a new DSQL connection string, so there's not much difference between them in this scenario. New conn string will trigger revalidation anyways, since that's the stuff that affects whether hyperdrive can still connect.

AJR•1/30/25, 5:54 PM

The dash uses PATCH, can't change anything there that would change our ability to connect so it can skip the revalidation traffic.

dave•1/30/25, 5:55 PM

I only need to update the the password. Everything else stays the same.

AJR•1/30/25, 5:55 PM

Ah, neat. I misunderstood what DSQL was doing there.

Same answer though. Typos when entering a password is like half the reason that we do the config-time validation in the first place.

dave•1/30/25, 5:56 PM

To confirm, does changing the password with either PATCH or PUT cause a trigger revalidation?

AJR•1/30/25, 5:58 PM

Yes it does.

dave•1/30/25, 5:59 PM

cool, I'll do a blog post on it.

AJR•1/30/25, 5:59 PM

Nice! Share it here and we'll repost it around, if you like.

dave•1/30/25, 6:00 PM

ya I'm doing it for the SEO, so please do share and ideally link.

AJR•1/30/25, 6:00 PM

Don't hate the player, hate the game.

dave•1/30/25, 6:48 PM

@AJR Is there a way I can create a Hyperdrive without needing a valid password?

AJR•1/30/25, 6:49 PM

No, there is not.

dave•1/30/25, 6:55 PM

btw, so happy that the permissions required now shows up in the API docs!!

dave•1/30/25, 6:55 PM

I think this is new?

AJR•1/30/25, 6:56 PM

There was a big docs revamp recently, if I recall. All generated from our internal schemas. Very slick, and much less toil on our end. I really appreciate that team shouldering the project.

dave•1/30/25, 7:00 PM

I was going to hassle you to ask you about what permissions were neated, but nope, not needed!

Correct! We enforce unique names. We don't use it for any actual logic in Hyperdrive itself, but it makes life way simpler for things like wrangler or the dash
