Enterprise accounts can also use it. We enabled them.

Yeah ive noticed a lot with newer products people will attempt to use the bindings but get undefined because they have not updated wrangler... I dont think it would be too hard to look at keys not parsed and be like hey this isnt a valid key you might need to update or something... Or the remote/local thing also

Quick questions - in the demo, a new connection is opened for each request (if I'm right). Won't this overload the PostgreSQL server when there're for example thousands of requests each second?

Also, I've created a Hyperdrive Id using wrangler. Should the dashboard in cloudflare change, or will it stay like this?

And last - in local development, I can't access the database (works in prod after wrangler deploy). I'm receiving the following error:

Cannot read properties of undefined (reading 'connectionString')

Cannot read properties of undefined (reading 'connectionString')

Do I need to add any parameters to the dev start up?

Thank you!

MMatt Silverlock Not yet, but very soon - we want to support local dev.

Sam•10/5/23, 1:23 PM

Ah nvm about the local dev.

Isaac McFadyen•10/5/23, 1:42 PM

Hyperdrive is a connection pooler and avoids this exact thing. A few connections are opened from Hyperdrive, and then every request opens a new connection to Hyperdrive (but not the DB) so that your DB doesn't get overloaded.

Isaac McFadyen•10/5/23, 1:43 PM

Because connections are held open from Hyperdrive, the connections to Hyperdrive are very very quick and won't overload things.

Sam•10/5/23, 1:43 PM

Ahh ok, that's what I was thinking but I was not sure. Thanks for clarifying

Sam•10/5/23, 1:58 PM

For local dev, I'm trying this (pasting a string, if HYPERDRIVE is not available in the env), but I'm getting SSL issues. Is this happening for more people?

Or is my (managed by digital ocean) database cluster not set up correctly?

Can you DM me your database URL? There’s not enough info in the issue to debug unfortunately.

Matt Silverlock•10/5/23, 8:54 PM

It's not currently configurable: 20 is very, very low though and would impact performance (fewer conns in the pool == more waiting)

mattfreeman•10/6/23, 6:49 AM

Is the connection string returned by env.HYPERDRIVE.connectionString usable outside of workers, is it accessible on from workstation when connecting over Warp Teams into the same account ?

kianOP•10/6/23, 8:54 AM

Nope

Nikil•10/7/23, 3:07 PM

So am I understanding Hyperdrive correctly? It's basically the same idea as Cloudflare DNS w/ CDN-style caching but for DBs? That sounds cool...

Kkian Nope

mattfreeman•10/9/23, 5:53 AM

Any plans for this? It would be awesome use case to connect into a zero trust with Cloudflare Warps for team, point DataGrip at the hyperdrive endpoint and presume it gets hyperdriven from a near edge, and enjoy the acceleration of less chat between me and live DB 300ms away.

kianOP•10/9/23, 7:04 PM

kianOP•10/9/23, 7:06 PM

So it turns out the docs callout I was thinking of is actually in Workers AI, and there isn't one for Hyperdrive. Oops

Kkian Who will win, docs aside or https://github.com/cloudflare/workerd/pull/1266/

kianOP•10/9/23, 7:13 PM

My bets have shifted over to the PR now meowlul

kianOP•10/9/23, 7:14 PM

I guess docs asides are pretty easy to miss - it'd be cool for Wrangler to do the warnings (like it does for Queues in remote mode currently).

kianOP•10/9/23, 7:14 PM

I guess that's hard for remote mode which can support them independently of a new Wrangler release, but local should be fine.

Converted the hyperdrive example to work with Hono if anyone's curious:

import { Client } from 'pg';
import { Hono, MiddlewareHandler } from 'hono';

type Bindings = {
    HYPERDRIVE: Hyperdrive;
};

const app = new Hono<{
    Bindings: Bindings;
    Variables: {
        DB: Client;
    };
}>();

const dbMiddleware: MiddlewareHandler = async (c, next) => {
    c.set('DB', new Client({ connectionString: c.env.HYPERDRIVE.connectionString }));
    await next();
};

app.get('/', dbMiddleware, async (c) => {
    try {
        // Connect to our database
        await c.var.DB.connect();

        // Test query
        let result = await c.var.DB.query({ text: 'SELECT * FROM pg_tables' });

        // Return result rows as JSON
        return c.json(result);
    } catch (e) {
        console.log(e);
        return Response.json({ error: JSON.stringify(e) }, { status: 500 });
    }
});

export default app;

import { Client } from 'pg';
import { Hono, MiddlewareHandler } from 'hono';

type Bindings = {
    HYPERDRIVE: Hyperdrive;
};

const app = new Hono<{
    Bindings: Bindings;
    Variables: {
        DB: Client;
    };
}>();

const dbMiddleware: MiddlewareHandler = async (c, next) => {
    c.set('DB', new Client({ connectionString: c.env.HYPERDRIVE.connectionString }));
    await next();
};

app.get('/', dbMiddleware, async (c) => {
    try {
        // Connect to our database
        await c.var.DB.connect();

        // Test query
        let result = await c.var.DB.query({ text: 'SELECT * FROM pg_tables' });

        // Return result rows as JSON
        return c.json(result);
    } catch (e) {
        console.log(e);
        return Response.json({ error: JSON.stringify(e) }, { status: 500 });
    }
});

export default app;

Note that I've renamed "client" to "DB", otherwise its the same

meai1•10/10/23, 2:52 PM

I keep getting " not_entitled [code: 10000]" even though I can connect to the db via datagrip just fine. Do I need to create a token permission for hyperdrive or do I need a paid workers plan? It logs me into cloudflare via oauth so I dont know what I'm not entitled for

Mmeai1 I keep getting " not_entitled [code: 10000]" even though I can connect to the db...

Cyb3r-Jak3•10/10/23, 2:53 PM

Workers paid plan is required for hyperdrive

meai1•10/10/23, 2:53 PM

oh okay, thank you

alex (he/him)•10/11/23, 6:39 PM

if hyperdrive keeps connections in a warm pool, does that mean that serverless dbs e.g. neon wouldn't suspend to not pay for compute?

Unsmart•10/11/23, 6:41 PM

If they charge by connection hours then I would assume that would be the case yes

kianOP•10/11/23, 6:41 PM

There's an initial connection timeout of 15 seconds and an idle connection timeout of 10 minutes.

kianOP•10/11/23, 6:42 PM

Neon's default auto-suspend delay is 5 minutes

kianOP•10/11/23, 6:42 PM

I imagine Hyperdrive might let you configure the timeout periods down the line

alex (he/him)•10/11/23, 6:42 PM

Ok that means neon will stay online 10 minutes instead of the 5 minutes?

alex (he/him)•10/11/23, 6:42 PM

Or are idle connection not forcing the db to stay online?

Colin•10/11/23, 10:52 PM

hey y'all - wanted to ask if anyone had opinions regarding Neon w/ Neon's connection pooling vs Neon w/ Hyperdrive (aside from the "one is GA and one isn't")

Colin•10/11/23, 10:53 PM

It seems like the main Hyperdrive-specific features are query caching + analytics (not yet but soon)

Colin•10/11/23, 10:54 PM

does anyone have experience with it / have any thoughts i might be missing?

import { Client } from 'pg'; import { Hono, MiddlewareHandler } from 'hono'; type Bindings = { HYPERDRIVE: Hyperdrive; }; const app = new Hono<{ Bindings: Bindings; Variables: { DB: Client; }; }>(); const dbMiddleware: MiddlewareHandler = async (c, next) => { c.set('DB', new Client({ connectionString: c.env.HYPERDRIVE.connectionString })); await next(); }; app.get('/', dbMiddleware, async (c) => { try { // Connect to our database await c.var.DB.connect(); // Test query let result = await c.var.DB.query({ text: 'SELECT * FROM pg_tables' }); // Return result rows as JSON return c.json(result); } catch (e) { console.log(e); return Response.json({ error: JSON.stringify(e) }, { status: 500 }); } }); export default app;

That sounds like it should be specific to Enterprise accounts? @Matt
