AAJR We haven't tested with Diesel, so YMMV.

Diesel uses sqlx under the hood I believe

TThe Infinite Diesel uses sqlx under the hood I believe

AJROP•4/8/25, 10:33 AM

Ah, I didn't know that. sqlx is not well supported today, I'm afraid.

It sends explicit Close messages that chew up an extra round trip instead of just dropping the connection and letting the origin DB garbage collect the prepared statements it generated, and that's not something we support currently. The bookkeeping for that is surprisingly complicated for a tx-mode pooler, and there would be a big performance penalty for doing it naively. I've poked at it a couple times.

The Infinite•4/8/25, 10:36 AM

It might be using tokio-postgres too though, I am really not sure

Since I am using Deadpool for pools with diesel-async

The Infinite•4/8/25, 10:38 AM

Well, aparently it uses libpg directly

@Hyperdrive Two big ones today for Hyperdrive:

Hyperdrive now supports MySQL: https://developers.cloudflare.com/changelog/2025-04-08-hyperdrive-mysql-support/
... and it's now on the Workers Free plan: https://developers.cloudflare.com/changelog/2025-04-08-hyperdrive-free-plan/

AJROP•4/8/25, 1:03 PM

Heyyyyy there we go. :soontm: has arrived! I can finally talk about MySQL stuff.

AJROP•4/8/25, 1:20 PM

Ah, also. Here's a blog on now Hyperdrive actually works. We're finally able to really get into the weeds of it, and I had a blast writing this.

Super excited for these two to land! We've been putting a ton of work to make Hyperdrive your go-to choice, looking forward to getting all the feedback!

AJROP•4/8/25, 2:50 PM

We tested in GCP and do support it. We also explicitly do support mysql_native_passwordmysql_native_password. I'm surprised, that's basically the happy path for us.

@thomasgauvin first bit of beta feedback here. I'll defer to you on the best way to capture details here.

Nick•4/8/25, 3:02 PM

I'm super excited for mysql hyperdrive. I am wondering, there was a question a year ago about read replicas. It sounds like that's not necessarily supported right now?

AJROP•4/8/25, 3:03 PM

Not at the moment, no. It's still something we're looking at doing, but no firm commitments on whether/when just yet.

Nick•4/8/25, 3:03 PM

okay, i guess one option is to have two clients, one for writing and one for reading, and use hyperdrive for writing?

AJROP•4/8/25, 3:04 PM

That's one option. It's probaly more performant to have hyperdrive for both, imo. Just point the reading configs at your replicas. Our internal teams do it that way for the moment.

Nick•4/8/25, 3:05 PM

okay, if i have geographically distributed read replicas is it smart enough to have endpoints in multiple regions?

Nick•4/8/25, 3:05 PM

or would i need to know which read replica to point to?

AJROP•4/8/25, 3:06 PM

Ah. Unfortunately the second one, for now. That gap is why we're considering building in proper support.

Nick•4/8/25, 3:06 PM

right, gotcha

Nick•4/8/25, 3:07 PM

im not sure if planetscale has a way to point to a specific replica, will need to dig into it. thanks!

kunal•4/8/25, 4:01 PM

For now, we have multiple hyperdrives (one for each replica), and use the cf geolocation headers to pick the right DB. But would be very excited to get rid of that custom logic and let Cloudflare route to the actual closest DB

AAJR Alright, looks like we're back to baseline latencies. CC @chimame

kunal•4/8/25, 4:04 PM

We got a bunch of alerts last night as well, and couldn't find any issues wrong with our Postgres instances so assumed it was Hyperdrive. Any chance these can be added to Cloudflare status in the future so it's a little easier to tell if its our fault or not?

Kkunal We got a bunch of alerts last night as well, and couldn't find any issues wrong ...

AJROP•4/8/25, 4:17 PM

That's reasonable. Let me talk to the team about it and get back to you.

KingMaker•4/8/25, 4:37 PM

@AJR hey. Needed a little help with scaling hyperdrive.

We currently use Postgres with neon and we are currently hitting connection limits (1M requests per minute). We’ve plugged in hyperdrive and got it working but will occasionally hit connection limits.

Any pointers?

AJROP•4/8/25, 4:39 PM

Probably need to up your connection limit. DM me your account + Hyperdrive IDs and I'll get you increased.

We really need to make this self-service.

oritwoen•4/8/25, 5:08 PM

After connect mysql hyperdrive with mysql2 lib I have: " "message": "proxy request failed, cannot connect to the specified address", on requests

Nick•4/8/25, 5:17 PM

Has anyone had luck troubleshooting "Invalid certificate verification context" when creating a Hyperdrive configuration through a Tunnel?

Hey, I'm trying to create a Hyperdrive instance with a Render Postgres DB. I paste in the connection string (which works when I connect directly to it in my code), but I keep getting status "inactive" in the dashboard. I tried both creating through the dash and with the wrangler CLI, and didn't receive any errors or anything. Created a post in the community forums https://community.cloudflare.com/t/hyperdrive-instance-status-inactive/787613. Any idea how to resolve this? Thanks!

Emilio•4/10/25, 1:36 AM

If you were able to create the Hyperdrive config you're good to start pushing queries through it! Active vs. inactive on the dashboard just means that it has been used in the past 24 hours
