AFAIK, the

kenton•8/3/21, 7:23 PM

You can delete the whole namespace and recreate it from wrangler. We plan later to add the ability to list existing objects and perhaps to schedule a function to run on all objects.

kenton•8/3/21, 7:29 PM

at present it's likely to stay at the same pop. To move to a new pop, you'd have to wait until all cached traces of the old object have been wiped from the system, which could take a while. But we're still working on automatic migration.

kenton•8/3/21, 7:29 PM

(though if you deleted the entire namespace and created a new one, then nothing carries over)

But if we use storage operations on the waitUntil, we will be able to make a response without actually wait.

kenton•8/3/21, 11:06 PM

Ah. Yes, deferring code to run after the response has already been returned is inherently unreliable, because in the case of a failure, no one finds out. E.g. if the power goes out, the task might never execute, but since the user already received a response, they won't know. Output gates can't help with this, since they can't predict what you're going to do in the future after you return the response. Generally, I don't recommend doing this, except maybe for stuff that is fine to be unreliable, like logging.

Kkenton lol just came here to post that, you beat me

specifically parses the output of . It won't work with any string that wasn't specifically created by stringifying an ID from the same namespace.

idFromName()

idFromName()

takes any string you want and returns a unique ID corresponding to it.

in retrospect, the naming could have been better.

aspOP•8/4/21, 3:52 PM

I'm in Denmark, so I hit CPH by default. Though, due to VPN on my PC, I mostly connect to AMS.

aspOP•8/4/21, 3:54 PM

My latency to CPH is ~10 ms and AMS is ~25 ms.

codefrau•8/4/21, 3:59 PM

Try these for latency testing:

https://croquet.io/cloudflare/?ihlwFIj1Z9-BtUfoNAEzD0ItTEZl1qsZrpR8n_BNx2V
Click "test latency" a few times, and maybe reload to make a new request.

Aasp My latency to CPH is ~10 ms and AMS is ~25 ms.

codefrau•8/4/21, 4:04 PM

Looks like your VPN is slowing down things maybe? FRA should be a lot less.

aspOP•8/4/21, 4:05 PM

Oh, I'm on a mobile connection right now - that's definitely why. Will test it in ~30 min when I'm home

codefrau•8/4/21, 4:05 PM

Oh that is a problem too of course. In LA I sometimes get single digit latencies

on fibre at home

I "only" have 1000/500 over COAX (DOCSIS 3.1) :/

Speeds are great, but latency doesn't get lower than ~10 ms to anywhere

32ms, that looks better

aspOP•8/4/21, 4:19 PM

So 32 ms is roundtime from my PC to FRA via CPH?

codefrau•8/4/21, 4:20 PM

yes

codefrau•8/4/21, 4:20 PM

the worker is in CPH and the DO in FRA

aspOP•8/4/21, 4:22 PM

Doesn't 50 ms seem seem alright then, if it's from my PC -> Amsterdam (VPN) -> CPH (Worker) -> FRA (DO)?

codefrau•8/4/21, 4:25 PM

I guess it is – I am spoiled by having the worker right here next to me

aspOP•8/4/21, 4:26 PM

I don't think there's anything to do about the ~10 ms latency added just to get out of the house

codefrau•8/4/21, 4:49 PM

Just to correct this - your connection from Amsterdam did not go via CPH. There is a colo in AMS, so that’s where the worker was.

codefrau•8/4/21, 4:49 PM

(the “via” item in the latency display is the worker colo)

aspOP•8/4/21, 4:53 PM

Ahh, alright - that's quite slow then, as I get 26 ms latency when running a Speedtest on the VPN. Cloudflare does peer with M247 in Amsterdam, right?

aspOP•8/4/21, 4:56 PM

Hmm, pinging (on VPN to M247 in Amsterdam) gives me a latency of 28 ms, so perhaps the route between AMS and FRA is just slow for some reason?
