Am I right with this calculation of a cost of $4.15 per month for a Durable Object to run 24/7?

86400 seconds x 128 MB = 11059200
11059200 / 1000 (1GB) = 11059.2
11059.2 x 30 (30 days) = 331776
331776 / 1000000 (million) = 0.331776
0.331776 x $12.50 = $4.1472

MMisterNight since you can toss in regular workers

I didn't know you could "toss in regular workers" to Pages so my info may be outdated... unless you are referring to Pages advanced mode?

MMisterNight ah, even if they can be represented as migrations in the wranglers.toml it must ...

Larry•3/5/23, 3:23 PM

As far as I know wrangler.toml is ignored by Pages CI. I think I remember seeing somewhere that now

wrangler pages dev

wrangler pages dev

will pull from it though.

For a single Durable Object, leaving it running 24/7 would make it fall under the "free" allotment of GB-S for Durable Objects.

zegevlier•3/5/23, 4:08 PM

That's very similar to what I came up with when I calculated it. But as HW said, running a single one for a month is included in the base paid tier

Unsmart•3/5/23, 6:59 PM

Pages are workers yeah but some features arent exposed through them. Pages is basically opinionated way to write and deploy workers so durable objects as part of a pages worker isnt exposed yet. Though you can bind to durable objects that other workers expose.

DanTheGoodman•3/6/23, 1:37 PM

I am trying to run a background promise to drain logs in a durable object that looks like this:

const res = new Response("broadcasted")
logger.Drain()
return res

const res = new Response("broadcasted")
logger.Drain()
return res

With

logger.Drain()

logger.Drain()

looking like:

async (lines) => {
  console.log("draining logs!")
  await googleDestinationFunction(lines, c.env)
  console.log("done!")
}

async (lines) => {
  console.log("draining logs!")
  await googleDestinationFunction(lines, c.env)
  console.log("done!")
}

Looking at my execution logs within cloudflare, I see only the

draining logs!

draining logs!

log, but not the

done!

done!

log. I've also tried returning the

googleDestinationFunction

googleDestinationFunction

log directly (which also contains logs that I do not see) and it just seems like the DO is exiting once the promise starts running... It is my understanding that the DO should let any other promises run the in background, correct?

MMisterNight answer: it has to have a worker, doesn't need a fetch handler, just has to exist

Hello, I’m Allie!•3/6/23, 5:17 PM

Note too that you can disable the

workers_dev

workers_dev

route, so the Worker itself cannot incur any Requests.

MMisterNight where? in _routes.json?

Hello, I’m Allie!•3/6/23, 5:19 PM

No, in your

wrangler.toml

wrangler.toml

MMisterNight in this example, would it look like `export default {}` ? https://github.com/clo...

Hello, I’m Allie!•3/6/23, 5:20 PM

It might work with just the

export class MyDOClass

export class MyDOClass

, but if it doesn't just add the

export default {}

export default {}

MMisterNight do you have any suggestions for dev mode? should I be mocking out the worker int...

Hello, I’m Allie!•3/6/23, 5:22 PM

wrangler

wrangler

should be able to connect to a DO automatically. If you run

wrangler dev

in your Worker, and then

wrangler pages dev dist --do BINDING=MyDOClass

wrangler pages dev dist --do BINDING=MyDOClass

, they should be able to link together...

Unsmart•3/6/23, 5:25 PM

dont think it matters that much but do note that when you deploy a worker all DOs will reset all active connections to do a code update and might throw some errors for a second or so

Hello, I’m Allie!•3/6/23, 6:18 PM

Jacob Wright•3/7/23, 7:41 PM

Are DO auto-migrations (moving the data and DO closer to where it is being consistently accessed) still something Cloudflare is considering for the future? Is it still a ways out, or is it going to be worked on "soon"?

Cckoeninger not actively being worked on but in planning, if you have feedback on your use c...

I have a lot of data centrally located in a database. I want to move it all to Durable Objects. I don't want to wait until a customer logs in for the first time to run the data migration for their data into the Durable Objects for their account and projects. At least, I don't want to make that a requirement, since many users have historical data but are not currently using my service.

I'm thinking I would run all the migrations ahead of time and current/previous users would have their data located near the original data center rather than near them. New customers would get their data located near them.

It will be nice if those current customers eventually had their data moved closer to them. Seeing that they currently don't have the data close to them, it isn't a big deal that their data won't be close, but it would be nice to have.

Jacob Wright•3/7/23, 10:18 PM

DO storage uses the structured clone algorithm. Do you know if there are any data protocol libraries available that can send that same data over the wire to a client application? protobuf or messagepack or anything?

Unsmart•3/7/23, 10:20 PM

Would be neat if DOs took in smart placement but a little bit more complex rather than just latency to external fetches took in the latency to requester locations and tried to place it in the best location latency wise for all of request latency and external fetch latency. I assume that would be very complex though

Jacob Wright•3/7/23, 10:20 PM

I'd like to create a data console to inspect the data in my durable objects and am deciding if I should just support JSON or all the types

Jacob Wright•3/7/23, 10:21 PM

I suppose I should have asked first if there are any GUI/UI consoles to manage DO storage. That isn't something Cloudflare is working on already, is it?
