Learn how to automatically manage rotating credentials and AWS IAM tokens for PostgreSQL databases using Cloudflare Workers and Hyperdrive.
ACorrect! 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
Deven after deleting?
ANo, should be fine after deleting...
AHmmmm. I see what happened here. I'll file a bug. Thanks for the catch
ANice, very well written. Let me crosspost that a bit.
JWe're seeing a spike of errors causing
postgres to internally explode: https://i.james.pub/file/2025/01/d4f49e0e-2876-40a2-98e3-a84eaa719bdc.png. DB ID edbe490e790c44389774f0c88667e221. Anyone else?
DIn what timeframe?
Jstarting 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
Dah yeah, that's Neon for you.
DI would recommend looking at AWS RDS Aurora Serverless v2. It's really nice IMO.
Dwe did have PostgreSQL errors around this time, but I don't know if it was the database or Hyperdrive causing the errors.
ALet me take a look
A@James what's your Hyperdrive ID?
ANot seeing anything widespread in our logging or metrics
Jedbe490e790c44389774f0c88667e221 - but after disabling Hyperdrive it looks like we're just timing out to Neon us-east-2
JSo not a Hyperdrive issue thankfully, but thank you
ASucks, hope you get it sorted.
II checked Neon's status page and there's nothing, annoying that there's random errors :\
Mjust basic RDS Postgres has been brilliant for my side project, 4 years without downtime
DLook 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.)

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

HI don't know if I'm looking in the right place, but $132.54 a month for a Side Project seems very expensive...
DShould 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.
HYeah, 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)
HIf 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.
DNeon is $69/m for 750 hours
HNot 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
HI 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
DRDS can scale down to about $5/m in that case though.
DAh agreed, if you want a bunch of separate instances/projects, Neon is cheaper for dev use.
DIs it possible for Hyperdrive to pool connections from different databases if the username/password is the same? Or is this a PostgreSQL limitation?
DAnswer: PostgreSQL limitation.
AWell, 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?

FI just entered the app, I don’t understand anything yet
LHi, I can see only 20 hyperdrive connections's on Cloudflare Console. There is any way to see all of them?
LWith wrangler's command, I can't see more than 20 too
LThe max number is 25
LAnother 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.
AKnown bug, the fix for that is releasing this week.
ASorry, I'm not following. Historically Hyperdrive has allowed 20 connections per region per Hyperdrive. What maximum are you referring to?
LThe maximum is 25 (right now I've 24, but I can see only 20)
AWhat maximum?
LThe quantity of Hyderdrive objects
AOh, you're referring to the number of Hyperdrive configs! Sorry, took me a second.
You can use the list API to see them all.
You can use the list API to see them all.
Lbut with wrangler hyderdrive list I can't see all
LAPI list by postman you say?
ANot sure why wrangler would be truncating those, I'll check with the team.
Any http client really. I just use curl

LOkki! I need retrieve de config Id... I'll try
AList API for your account should return the IDs as part of the json
MYou should be able to see multiple pages of results now (in the dashboard)
LYeah, thanks!
