Ddave am I not allowed to reuse names?

AJROP•1/30/25, 10:09 PM

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

Hmmmm. I see what happened here. I'll file a bug. Thanks for the catch

Nice, very well written. Let me crosspost that a bit.

In what timeframe?

James•1/31/25, 12:34 AM

starting around 25 minutes ago, at 00:07 UTC. It's looking like our DB at Neon might be the cause here though and not Hyperdrive

dave•1/31/25, 12:34 AM

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.

AJROP•1/31/25, 12:36 AM

Let me take a look

AJROP•1/31/25, 12:44 AM

@James what's your Hyperdrive ID?

AAJR Let me take a look

AJROP•1/31/25, 12:45 AM

Not seeing anything widespread in our logging or metrics

but after disabling Hyperdrive it looks like we're just timing out to Neon us-east-2

James•1/31/25, 12:45 AM

So not a Hyperdrive issue thankfully, but thank you

AJROP•1/31/25, 12:46 AM

Sucks, hope you get it sorted.

Isaac McFadyen•1/31/25, 12:48 AM

I checked Neon's status page and there's nothing, annoying that there's random errors :\

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, 7:53 PM

Yeah, idk what Max is running, but side project, in my mind at least, is something that would fit on a free-tier Supabase/Xata/Neon(also since you probably don't need redundancy or other jazz)

Hard@Work•1/31/25, 7:54 PM

If you bundled many projects together onto a single database, it might be more worth it, but imo it's still a lot more pricy than the hobby alternatives.

HHard@Work Yeah, idk what Max is running, but side project, in my mind at least, is somethi...

dave•1/31/25, 8:45 PM

Neon is $69/m for 750 hours

Ddave Neon is $69/m for 750 hours 😦

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

Hard@Work•1/31/25, 8:52 PM

I sure know every project I have deployed(other than WDOL) has DBs cold-starting, because I definitely don't have enough usage to keep them alive all the time. YMMV may vary of course, depending on your project

HHard@Work Not necessarily? You should be fine for a whole month if you go 0.25 vCPU, 2 GB ...

dave•1/31/25, 10:12 PM

RDS can scale down to about $5/m in that case though.

dave•1/31/25, 10:13 PM

Ah agreed, if you want a bunch of separate instances/projects, Neon is cheaper for dev use.

AJROP•2/1/25, 12:00 PM

Well, we get to cheat a little, with the runtime-generated connection strings.

We probably could if we wanted to. Not saying it's something we'll do, but I'm curious and have never considered that before. What would be the use case for something like that?

Fernanda lustosa•2/1/25, 4:21 PM

I just entered the app, I don’t understand anything yet

letincho5•2/3/25, 11:07 AM

Hi, I can see only 20 hyperdrive connections's on Cloudflare Console. There is any way to see all of them?

letincho5•2/3/25, 11:21 AM

With wrangler's command, I can't see more than 20 too

letincho5•2/3/25, 11:21 AM

The max number is 25

letincho5•2/3/25, 11:39 AM

Another topic, I think there is a bug in delete hyperdrive feature: after delete a hyperdrive, I can't create another hyperdrive with the same name, because it's already exists.
