Interesting. I searched and you're right, TCP connect from workers to DO seems to have some issues.

I'm not sure if it's due to the shared address range or not, though.

I'll check Monday with my teammate who's working on the migration to the CF IP ranges and see if we have a way to test if DO cooperates with those. I'd be curious to know, honestly

I have digital ocean and azure credits to burn and the latter seem to be priced crazily so would be ideal!

Maybe if there is no solution with public there is one with private connection?

I’d be open to using d1 instead also but I have about 50gb of data already so I don’t know if limits can be increased to say 100gb (for future scale)

Also happy to discuss using r2 as this is mostly a primary store of library like data with reads being carried out from my typesense instance.

I am on CF startups program also

Might be in a better spot to address what will fit your use case best.

Hey,
I am not sure what Hyperdrive is, but does this make it possible to have a database being hidden behind the Cloudflare Network?

Yes. Our tunnel integration does exactly that.

I want to hide my database behind Cloudflare's Network without needing to have the CloudflaredCloudflared application on all devices..

Is that what Hyperdrive fixes?

AJROP•2/9/25, 2:52 PM

Hyperdrive is a way to talk from Workers to a centralized database. We integrate with tunnels too so you'd only need have cloudflared running once somewhere within your vpc to egress the traffic to your DB from.

Based on your questions I'm assuming you're not running your application on Workers?

Stilau•2/9/25, 2:56 PM

No I am not..

AJROP•2/9/25, 2:57 PM

Okay. This is another interesting use case for non-workers ingress for us. I'll mention this over to our product folks.

AJROP•2/9/25, 2:59 PM

For now though, Hyperdrive probably isn't going to be a lot of help for your use case, I'm afraid.

Sweet thank you, let me know on the digital ocean stuff when back into the office just to get a firm answer if possible vs not.

Then I can explore alternatives if its a definite no!

Happy to speak to @thomasgauvin

also. As exploring alternatives is totally fine too.

This is correct, Hyperdrive is not on Cloudflare's IP range @Nick

João Castro•2/10/25, 9:42 PM

Are there any plans for supporting custom connection limits per region? Right now we seem to be hitting that limit and losing performance by being routed to a nearby region.

AJROP•2/10/25, 9:43 PM

We're moving away from regional pooling, which should dramatically improve that without the additional config needed

Shados•2/10/25, 11:46 PM

Hello~ I was reading about hyperdrive, and wanted to confirm something: is hyperdrive ONLY for accessing a database from workers, or can it be used for connecting from other type of distributed applications (that aren't hosted on Cloudflare?).

I assume the answer is "nope, sorry!", since it looks like Hyperdrive operates as a worker binding, but just want to confirm.

AJROP•2/11/25, 12:04 AM

Yes, that is correct. We've kicked around opening it up more, but have not committed to that yet. Hyperdrive operates as a standalone service, so it is technically possible, though would take some work.

If you're willing to discuss your use case a bit, it'd help us as we evaluate.

dave•2/11/25, 2:21 PM

@AJR Hmm, I think I may have found a pretty bad bug. When you reconnect, are you doing a fresh DNS lookup, or are you maybe accidentally using a cached entry?

dave•2/11/25, 5:39 PM

Neon suggestions without the pooler.

Cloudflare suggests with the pooler.

In most scenarios, a new pool will be created when you send traffic after the PATCH change to your configuration, and the existing connections will idle and then time out.

AJROP•2/13/25, 10:38 PM

Well, we'd need to build it. It'd be pretty doable, it's just not something we've had to do before.

AJROP•2/13/25, 10:38 PM

But no, we don't currently have a "nuke this pool" button available to us.

AJROP•2/13/25, 10:41 PM

Unrelated: we've started teeing up migration of existing Hyperdrives to the new pool placement system. I love my demo page screencaps, so here y'all go.

dave•2/13/25, 10:53 PM

Could we have have the same/similar page that shows the stats like that for our Hyperdrives?

thomasgauvin•2/14/25, 2:33 PM

@dave | ai.moda what do you think of hyperdrive's current analytics on latency? ie what are you looking to get out of this
