When DO stops being durable 🤣

Basically what is described here https://developers.cloudflare.com/workers/learning/using-durable-objects#risk-of-data-loss

or does that only apply for in-memory state?

Ahh.. that is a generic disclaimer while Durable Objects are in beta.

And no system can 100% guarantee no data loss, but once we are GA I am sure there will be one. The entire system is designed to minimise loss of data as much as possible of course.

That all counts for data that is written to storage. You should expect any in-memory state to be lost at a moment's notice.. It can be evicted, DO can crash.. etc

Oh, I see! Thanks a lot!

Anyone know if the structuredClone() method for deep cloning objects is available in workers/DO? Or something comparable to Node's v8.serialize()?

Is there any update on what the pricing for DO will be for Workers Bundled?

*Coming Soon*™️

is that soon like today soon or like next year soon?

*Soon Soon*™️

We don't know, we can only hope...

I don't think it is, but durable objects can store any values supported by the structured clone algorithm, so you could do

await storage.put("key", value); const clone = await storage.get("key")

😄

ugh.. I want to use DO, but not knowing how much they will cost is.... annoying

Pricing was announced here: https://blog.cloudflare.com/durable-objects-open-beta/

May or may not have already been covered, but do cached storage operations still count for billing?

^^ I'm very interested in hearing this as well

it's missing if anything is included in "Bundled" or not or will DO only be available for "Workers Unbound"?

They are available with both.

right... so what is included (if anything) on the paid plan?

or is it the same as this? https://developers.cloudflare.com/workers/platform/pricing#pricing-1

To be clear, a DO can be called from a bundled worker or an unbound worker. DOs have their own pricing. Are you asking about whether any DO billing in included in the first $5/mo of a paid plan, or?

Yes. I guess that is my question: Does the free tier or the paid tier (bundled) include any DO usage?

I'm not sure if that has been decided /cc @User

Paid tier does included some usage, free tier does not yet (but coming soon)

cached storage operations do currently count for billing.

cool beans! can you share how much usage the paid tier includes?

Is there any way to horizontally scale durable objects? I have a websocket worker which puts websockets into rooms, each of these rooms is a durable object which holds the array of websockets connected to it, since all of the websockets are "centralized" in this durable object, when you hit a high number of websockets, this will become very slow because of having to iterate over a huge list of websockets, ideally I would distribute the websockets of the same room across multiple durable objects but then doing things like broadcasting to all websockets in a room would become impossible currently (afaik). Any ideas?

> high number of websockets, this will become very slow because of having to iterate over a huge list of websockets will it though? have you validated this assumption? what is "huge" are we talking millions?
