Tor is one example as it has no GeoIP

Kkian Tor is one example as it has no GeoIP

About this point, the documentation under « Region » field precise « if known », but it's not the case of « country », do this mean country is always available (even with Tor) ?

Country will be T1

Hello

I am new on the discord

I am checking on what could be a good way to improve our workers/DO deployments, to quickly rollback in case of problem in an automated fashion. So I was looking at the cool stuff like canary deployments, blue-green, etc. Using potentially logs or analytics engine to generate metrics defining if the new release is healthy

As we use DOs, it is not so easy to replicate all our workers & DOs, put a gateway in front and send part of the traffic to the new deployment.
Out there projects like these seems abandoned: https://github.com/stuartsan/cloudflare-workers-kv-canary-releases, this one as well
https://github.com/DigitalOptimizationGroup/blue-green-cloudflare-workers
Any thoughts on this topic?

Walshy•5/11/23, 12:01 PM

I'd probably use Analytics Engine to monitor and then act on that data to rollback. Workers has built in rollback, so I'd just use that endpoint

Aster•5/11/23, 12:03 PM

How would you deal with slowly releasing a new version (geo/region release?) Is it possible?
The idea would be to not shift the whole traffic on deploy et rollback in case of problem (eventually we might do this if nothing else is possible)
But instead focus on canary release to impact only a small portion of users when introducing an unexpected change

Walshy•5/11/23, 12:12 PM

A few ways to do that today like in the projects you linked. No official way today though

Aster•5/11/23, 12:14 PM

So it is possible to deploy per region? I didn't see references to it in the documentation ^^

kianOP•5/11/23, 12:26 PM

Nope

Walshy•5/11/23, 12:26 PM

I mean you technically could

kianOP•5/11/23, 12:26 PM

You’d need your own Worker to do any routing based on region to a new/old service

Walshy•5/11/23, 12:26 PM

Check cf obj and pick from one or another

Aster•5/11/23, 12:28 PM

But then wouldn't the DO data be off? (still new with DO, not 100% sure)

Walshy•5/11/23, 12:28 PM

Basically you'd do like a router Worker which picks which Worker to serve (based on percent, region, etc)

Just found my answer, if I believe the source code of workerd ( https://github.com/cloudflare/workerd/blob/89199545cf23160ff30efd5ba331a933fc8310f1/types/defines/cf.d.ts#L512 ) this should be based on ISO 3166-1 ( so in theory "MQ" if detected in the region "Martinique" of "France" )

I can't find any VPN/proxy based on this kind of islands ( Martinique, Guadeloupe, La Réunion, ... ) to test, not found VPS hosted on theses islands, so I can't simulate someone calling my worker to confirm that... if someone have a clever idea to help me, this will be appreciated !

TTerroFlys What IDE's do you guys use when making workers?

yeah, I do that for proxying our website's third party chat application.

I modify/string replace problematic paths.

Hi, regarding KV, If I don't need the replication accross the globe, would R2 be a cheaper alternative ?

Ian•5/11/23, 11:39 PM

Since R2 in a way behaves like a key value storage?

Cyb3r-Jak3•5/11/23, 11:59 PM

R2 is going to return an R2ObjectBodyR2ObjectBody which you then need to parse in your worker to get the value of

Yes. You can either hydrate and change it on the client, or (probably the better way) do it in a Function which is the Pages equivalent of a Worker: https://developers.cloudflare.com/pages/platform/functions/

Ian•5/12/23, 12:33 AM

Sounds like an good option because I plan to store small objects in it, I want to confirm how the duration is billed (no websockets), say I want to read an object once and then once again 1 second after, do I get billed ~1 seconds or just the split milliseconds that the DO was actually working on those reads ?

Unsmart•5/12/23, 12:36 AM

You’ll only be charged by the ms. The duration billing for DOs when all you do is storage ops is so insanely negligible that I don’t even count it normally

Ian•5/12/23, 12:41 AM

Got it thanks, there is a request limit of 150rps per DO, there will be a few DOs that is potentially being requested a lot, it seems that I can use the Cache API for that, I don't read article regarding pricing or rate limits, want to confirm that it's free and does not have an upper limit ?

Unsmart•5/12/23, 1:48 AM

Cache is free for unlimited RPS.
