This is probably due to enabling client cert security on the DB which Hyperdrive doesn't currently support, see Great news!, I was trying to test it

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!

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

For local development, you have to use a local database. You can also do local development with npx wrangler dev --remotenpx wrangler dev --remote, where your Workers are run in Cloudflare and that will allow you to connect to your remote database

any chance someone on the hyperdrive team can give the folks working on the cloudflare vite plugin a gentle nudge. while wrangler dev succesfully polyfills everything required for mysql2 to run, the cloudflare vite plug in doesn't. my best guess is this is due to unenv not handling safer-buffer https://github.com/unjs/unenv/issues/486

background: i host mysql at 127.0.0.1:3306 and rely on gre tunnels for inter-server communication

muqsit•4/12/25, 8:39 AM

it appears, with hyperdrive you have to expose your server to public ip

Alex•4/14/25, 2:00 AM

So my Hyperdrive connection with MySQL just started throwing errors, or well it started not responding. https://screen.bouma.link/fGflgtK5X2vH5wrX98nZ

From the Cloudflare Dashboard everything is "Active" (Hyperdrive) and "Healthy" (the Tunnel) and cloudflared also is runnign without any log output. But workers connecting throw:

Connection lost: The server closed the connection.

Connection lost: The server closed the connection.

Any clue where to start debugging this? The MySQL server is doing fine and nothing has changed on my end (I was asleep when the incident started). But I expected there to be some visible fault somewhere

Cloudflare side issue?

I cannot for the life of me create a hyperdrive connection to my Neon PG DB. It is always stuck in "inactive" and returns an error when attempting to use it "SERVER_ERROR: NeonDbError: Server error (HTTP status 530): error code: 1016"
Is there some black magic I need to perform on the Neon side of things (because the hyperdrive side seems super simple)

Ramtin•4/19/25, 5:38 AM

Hi all,
Do we need to create a new SQL connection for every request with Hyperdrive and close it after fetching the data, or should we create a single connection instance and reuse it? The latter approach seems more reasonable to me but it doesn't appear to work on Workers.

plurk•4/20/25, 9:37 PM

We are using hyperdrive with postgres and drizzle which is being called from pages worker functions. We encountered a nasty bug which took a few days to be narrowed to one API call.

API endpoint is beyond simple, does just 1 db query:

const map = await db.query.maps.findFirst({
  where: eq(maps.geoguessrId, params.geoguessrId)
});
if (!map) {
  return json({ mapFound: false }, { status: 404 });
}

return json({
  mapFound: true
});

const map = await db.query.maps.findFirst({
  where: eq(maps.geoguessrId, params.geoguessrId)
});
if (!map) {
  return json({ mapFound: false }, { status: 404 });
}

return json({
  mapFound: true
});

Clients were falsely receiving mapFound: truemapFound: true on occasion. Logging in pages functions is very limited, but we we were able to reproduce the bug by barraging the API with requests until it falsely returns mapFound: truemapFound: true.

The mapsmaps table doesn't change often - a few modifications a day at best. Seems like a hyperdrive bug to me, but I don't have any evidence to support it except for the info provided above.

plurk•4/20/25, 9:42 PM

The problem does not happen locally. We added map.geoguessrId !== params.geoguessrIdmap.geoguessrId !== params.geoguessrId as a bandaid fix in a desperate attempt to fix it and it seems to be doing the trick. No idea what map object is being returned, logging would really help
