Backups are not an option neither a feature. It is an integrity and security core aspect born with computers. Cloudflare is great but Jesus the mindset behind few thing really needs to be revisited. This is why I was happy that open source altertives like Rivet would come to shake these nonsenses that make such a great feature a no-go for many businesses and projects.

There are a couple of things that look like really weird decisions to me as well. The ones that cause me the most frustration are around creating too much "magic" like Smart Placement without the possibility of setting a hint, and Queues that don't let you set concurrency manually. If it "just worked" it would be incredible but it was not or still isn't the case for well over a year. Hyperdrive did make things better, though.

Introduction

Cloudflare Realtime can be used to add realtime audio, video and data into your applications. Cloudflare Realtime uses WebRTC, which is the lowest latency way to communicate across a broad range of platforms like browsers, mobile, and native apps.

cloudkite•11/9/25, 8:02 PM

Unfortunately it’s kinda a typescript shortcoming, in the cloudflare type definitions RPC maps all functions of an object to make them async. Typescript doesn’t preserve generics when you do this, therefore you lose things like branded types.

cloudkite•11/9/25, 8:04 PM

Workaround we have used is to recast to correct type. Which if you have some kinda wrapper around your DOs is workable since you can isolate the hack to one place.

matt•11/10/25, 5:24 AM

when using durable object script_namescript_name option for local dev, the generated binding lacks a type parameter, usually provided to the namespace generic, ie.

DOSTORE: DurableObjectNamespace /* DurableObjectStore from durables */;

DOSTORE: DurableObjectNamespace /* DurableObjectStore from durables */;

versus what you'd normally expect:

DOSTORE: DurableObjectNamespace<import("../.svelte-kit/cloudflare/_worker").DurableObjectStore>;

DOSTORE: DurableObjectNamespace<import("../.svelte-kit/cloudflare/_worker").DurableObjectStore>;

Just to be clear. D1 and SQLite DOs support Point in Time recovery for any point in time up to 30 days in the past.

What I a mentioned above was for things like backups elsewhere, to different DBs, or offloading backups to another product like R2 or even different providers.

lambrospetrou•11/10/25, 9:33 AM

As you will see over the next few weeks/months, a lot of these things will be improved. As a platform Cloudflare evolved a lot over the years, and yes, a lot of the mindset and priorities changed due to how customers are using the platform and how certain "magic" as you say didn't come to fruition. (Personal opinion, but I personally dislike anything "magic", if you could see it from my suggestions over the past year, so I am with you on that one

)

So, as I always say, giving constructive feedback in what you would like to see change, or even new things, and justifying with legit use-cases is the best way to steer the platform towards delivering those things.

Larry•11/10/25, 1:45 PM

plgingras88OP•11/10/25, 2:57 PM

Oh absolutely, PIT was already part of my answer, but thanks for clarifying! Still, PIT is only a first-level safety net and indeed doesn’t solve the real issue : offloaded backups that ensure data integrity and security and easy way to import/export. Without these "features", backups and recovery in case of emergency become far too uncertain, left entirely to the user’s discretion and prone to human error.

SQLite definitely makes things more portable than KV, though. I just hope dumping the SQL file somewhere won’t take months (or years!) to arrive.

João Castro•11/10/25, 7:40 PM

That would be with transaction()/transactionSync()transaction()/transactionSync()

João Castro•11/10/25, 7:48 PM

For example we could have an outbox table:

Transaction starts;
Change/delete a row (Output Gate closed);
Send the message to an external system (Request blocked by the Output Gate. Deadlock?);
Receive a response;
Transaction commit/rollback depending on the response;

This should have at-least once delivery guarantee, so it would be ok to send the same message again in the case of failure to complete the transaction or SRS failing to make writes durable.

João Castro•11/10/25, 7:49 PM

Right now I think we would have to lease the message and send it outside of the transaction, and then the consumer would have to ackack it later.

lambrospetrou•11/10/25, 7:50 PM

TLDR: If the callback given to those functions throws, the transaction is rolled back. Anythinh done outside in external systems is up to you to stay consistent.

João Castro•11/10/25, 7:50 PM

João Castro•11/10/25, 7:50 PM

JJoão Castro So there is no way currently to make outgoing connections inside a transaction?

In most cases this would be a bad idea, but in the scenario I described above it should be reasonable and a simpler design

JJoão Castro That would be with `transaction()/transactionSync()`

Maintaining consistent state

Cloudflare durable objects maintain consistency in light of storage write failure, but not when your code throws an unexpected error.

Can a bidirectional channel service built on the QUIC protocol ( like WebTransport) be used in durable objects?

matt•11/11/25, 2:41 AM

hey all, quick docs question

im using the cloudflare adapter with sveltekit (which works via getPlatformProxygetPlatformProxy)

and this section provides instruction on using script_namescript_name in the binding to support local dev:

https://developers.cloudflare.com/workers/wrangler/api/#supported-bindings

however after setting up this way i'm seeing this error trying to call RPC methods on the stub:

Error: Cannot access "DurableObjectStore#initialize" as Durable Object RPC is not yet supported between multiple dev sessions.

Error: Cannot access "DurableObjectStore#initialize" as Durable Object RPC is not yet supported between multiple dev sessions.

the docs from the link above say this, but I'm wondering if that "not" (fourth word along) should not be there? and instead should it read "If you ARE using..."

If you are not using RPC with your Durable Object, you can run a separate Wrangler dev session alongside your framework development server.

Otherwise, you can build your application and run both Workers in the same Wrangler dev session.

in fact the only test that does use that fixture is just making sure the "internal" binding warning does not appear: https://github.com/cloudflare/workers-sdk/blob/4259256e33445b5f2ae290a68795be9c1852d860/fixtures/get-platform-proxy/tests/get-platform-proxy.env.test.ts#L286-L291

Larry•11/11/25, 12:19 PM

In order for that to be most useful from a DO, Cloudflare will also have to implement the equivalent of hibernating WebTrasport. It's on my wishlist too, but from what I understand, outside of WebRTC, Cloudflare has limited support for QUIC anywhere, so it'll be a while before that trickles all the way down to DOs.
