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?

AJROP•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.

AJROP•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.

AJROP•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?

AJROP•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.

AJROP•1/30/25, 5:59 PM

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

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?

AJROP•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?

AJROP•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!

I would recommend looking at AWS RDS Aurora Serverless v2. It's really nice IMO.

dave•1/31/25, 12:35 AM

we did have PostgreSQL errors around this time, but I don't know if it was the database or Hyperdrive causing the errors.

Let me take a look

AJROP•1/31/25, 12:44 AM

@James what's your Hyperdrive ID?

dave•1/31/25, 12:40 PM

Look at switching to Aurora Serverless v2; it now supports scaling to zero, which is great for side projects that don't need to be on all the time. (Takes <30 seconds to turn back on.)

https://aws.amazon.com/blogs/database/introducing-scaling-to-0-capacity-with-amazon-aurora-serverless-v2/

And it also has zero-downtime patching (ZDP)!

dave•1/31/25, 7:52 PM

Should be $43.8/m for 0.5 ACUs (assuming you never scale to zero) + $3.65/m for IPv4. Then there's some extra costs for bandwidth and I/O, but it's pretty small for (most?) workloads.

Hard@Work•1/31/25, 8:51 PM

Not necessarily? You should be fine for a whole month if you go 0.25 vCPU, 2 GB RAM. Or, too, there is the scale to zero, which again, for a side project, you might not need 24/7 uptime
