Ahh.. do you terminate the WS in the Worker or the DO?

Neither.

It just keep polling to keep the connection alive.

But the DO gets evicted because the ping-pong messages are not tied to the DO

This leads to the DO eviction but does not close the WS connection.

Would server-sent events count as the same limits and usage as a websocket connection being open? An websocket being open would count as your DO being active and paying the maximum 128MB ram per second. Would the same be the case for a http connection being open?

As long as the Durable Object is active, you will be charged.. no matter if there are 0, 1 or 100 WebSocket connections open 🙂

I'd like to call a specific endpoint (

/migrate

, you guess what it does) for all my DOs. What's the best way to do so?

Call the CF API, get all of the IDs, create a Worker that takes an ID, creates a stub, and calls

/migrate

, and then call it with all of the IDs.

Thanks! Found the CF API endpoint in question: https://api.cloudflare.com/#durable-objects-namespace-list-objects

Or https://developers.cloudflare.com/api/operations/durable-objects-namespace-list-objects, if you don't want to crash your browser 😜

surprisingly it's not a

.list()

function in the DO namespace (any reason?)

I believe DO's aren't globally documented, so a

list

would basically have to contact every DO-ready colo to collect the data

mmmh but does the CF API do that?

Yeah. I'm not saying it isn't possible, I'm just trying to explain what I think might be their reasoning behind why it isn't a native API.

Hello, I have a question about DO pricing. When I was buying the Paid plan I saw the next information: "+ $12.50 per additional 400,000 GB-second duration" However, on the docs page (platform pricing) I see "+ $12.50/million GB-s". Do I need to pay 12.5$ per 1M or 400K?

The 400k is for Workers Unbound, not Durable Objects

Durable Objects pricing is indeed the 1M: https://developers.cloudflare.com/workers/platform/pricing/#durable-objects

Unbound and DO are both 12.50 per million GB-sec

Thanks! I hope that cloudflare will fix this misunderstanding on the payment method page.

hello, i am on a paid workers plan and do not see an option to create Durable Objects

I don't see it either. But I waited for a while and an alert appeared on the workers/overview page and I clicked it.

Yup, I mentioned it to someone.

i just made a new function with wrangler and added durable object to that, deployed it, and now i can select the durable object binding

What's the general DO timeout time? Since DOs are charged for 'wall-time', when all operations are completed, how long until it is destroyed generally and a new contruct call will be done?

It's wall time of the the request being completed

Any suggestions what to do with

Cannot create binding for class ChannelsDO that is not exported by the script

? This class is clearly exported in my file. I have also defined

new_classes = ["ChannelsDO"]

inside migrations. The suggested

--new-class

flag seems to be targeted to Wrangler 1?

what does your durable_objects section look like? did you

export class ChannelsDO

inside the script

[durable_objects]
bindings = [  { name = "CHANNELS", class_name = "ChannelsDO" },  { name = "CHANNEL", class_name = "ChannelDO" }]

I'm using esbuild to bundle multiple TS files into one .mjs. The compiled MJS file ends with:

export {  ChannelDO,  ChannelsDO,  src_default as default,  handleRequest };

where

ChannelsDO

is a class.

main

inside

wrangler.toml

is pointing to that mjs file
