Thanks for the in-depth answer! Yeah it

Thanks for the in-depth answer! Yeah it somehow doesn't add up. But good to know that the cost is miniscule. Your use case sounds pretty much like ours. Do you happen to know a pattern for DOs to handle a big number of users - think global chat or feed. I was thinking of using a DO id stored in KV that's incremented as soon as a worker receives an overloaded error so every new requests uses the next DO instance. And another KV entry that stores all active DO ids for broadcasting to all of them....

Durable object best practice

1. yes 2. should in theory be more efficient yes since the connection is established already, but it's a different topic if your app will notice this optimization 3. I believe, yes, it's charged as far as I know. Not sure if hibernation can kick in and disconnect the target. Will double check. 4. Simplicity wise, not using the RpcTarget is better if it's just doing 2 calls. But, it can be more optimized if you will be doing lots of calls and want to avoid making an RPC each time. I didn't measure the difference nowadays but I suggest measuring it and seeing if it matters to your app....

If you want to think of it as a bug feel free. But just keep in mind that theres 0 expectation of close events of any form running. It will generally run for the most part but not always

Single Worker with DO,RPC and rrv7 with partial prerendering

ok i wonder if that's true because it seems like they are integrating something related to RPC as well

I try hard to design the DO parts of the system so that don't need any external fetches, mostly not for cost reasons but because it breaks the DO concurrency model. In the rare cases where I just couldn't design around that, I offload it to a Worker (sometimes through a Queue) who will "respond" by calling back to the DO when it has the answer. The "address" of the caller is passed along and used to get the "response" back to where it originated. JSON-RPC is really nice for this because it doesn...

I think I'd need to see what it's doing to make a certain answer here. If you're wanting to do it from the Worker and RPC into the DO and execute SQL you could do it like this but I also can just be 0 coffee's deep this morning and misssing the question altogether šŸ˜…

json-rpc-mixin

Ummm, I am not sure about the lack of await just because of service bindings? But yes, you can get back to the DO ā€œaddressā€ either with fetch or non-callback Cloudflare native RPC. As a side note, my ā€œaddressā€ goes all of the way back to a particular browser using JSON RPC. I currently use HTTP between Cloudflare contexts but if I were building it today I would probably use Cloudflare native RPC between Cloudflare contexts. Regardless, it is WebSockets between DO and the browser using Partykit via the Agents DO base class and AgentClient in the browser....

Known issues

Is there a way to gracefully roll out a new version of a Durable Object class? It states here that objects are reset when the code is updated: https://developers.cloudflare.com/durable-objects/platform/known-issues/#global-uniqueness. In my situation, Durable Objects are pseudo-stateful, streaming an LLM call to a user. If the object resets, this LLM provider call is interrupted, and there isn't really a way to gracefully retry (apart from reperforming the LLM request itself)....

Another great thing for my use case is that the old KV data will be essentially archived after this year. So I will just leave the KV namespaces as is, then create my SQL DOs as a 'v2' of my internal API

Output gate and async operations

Why are you concerned about the output gate I'm confused. Can you show a more accurate example? I don't understand the purpose of the psuedo-code you posted, it doesn't do anything

I can imagine using websocket would be more efficient. We built our previous chat API entirely over HTTP requests and polling, similar analogy. I can't speak to the specifics on a theoretically implementation using DOs as you have described. In production our current use-case necessitated we create a new client ws connection per DO. I don't see how using RPC between DOs would reasonably or efficiently solve the issue....

Let me give an example use case that demonstrates the issue then. Let's say we are building a cloud storage product, where customers can upload files, and each customer is billed for the total size of all their uploads. Let's build this with DO, where each customer has their own DO which stores the information of total size in SQLite storage. On a request for uploading a file, the DO would: - Upload the file to R2. - Increase the total size in storage....
