Erisa•7/5/23, 10:49 PM

Not quite what I had in mind but for your use case that.. might work? Maybe?

EErisa For live updates you should 100% be using a websocket

McSneakyOP•7/5/23, 10:49 PM

Yeah.. Dealing with legacy stuff.. Trying to figure out faster workarounds

EErisa Not quite what I had in mind but for your use case that.. might work? Maybe?

McSneakyOP•7/5/23, 10:50 PM

So instead of random hashes I'd have like

myfile.v1.js

myfile.v1.js

myfile.v2.js

myfile.v2.js

myfile.v3.js

myfile.v3.js

etc

MMcSneaky So instead of random hashes I'd have like `myfile.v1.js`, `myfile.v2.js`, `myfil...

Erisa•7/5/23, 10:51 PM

I've seen that done with some success

McSneakyOP•7/5/23, 10:52 PM

Noice. Thnx for discussions!
I can do redirects thro API all good

And that will work in production long enuf until I (or someone else) figure out how to update client side legacy code to support WS directly

Erisa•7/5/23, 10:53 PM

websockets are OP for live updates, its how your discord client is showing all our messages in realtime

dave•7/5/23, 10:54 PM

This is a guess:

Put these headers on the redirected

myfile.latest.js

myfile.latest.js

cache-control: private, no-transform, no-cache, no-store, max-age=0, s-maxage=0

cache-control: private, no-transform, no-cache, no-store, max-age=0, s-maxage=0

And these headers on

myfile.v*.js

myfile.v*.js

cache-control: private, immutable, no-transform, max-age=31536000, s-maxage=31536000

cache-control: private, immutable, no-transform, max-age=31536000, s-maxage=31536000

You should change

private

private

public

public

if these files aren't custom per-user.

dave•7/5/23, 10:56 PM

personally I would recommend using this for the redirect:

https://cdn.example.com/js/@teamname/productname@latest/index.js

https://cdn.example.com/js/@teamname/productname@latest/index.js

And like this for the versioned files:

https://cdn.example.com/js/@teamname/productname@1.2.3/index.js

https://cdn.example.com/js/@teamname/productname@1.2.3/index.js

McSneakyOP•7/5/23, 10:59 PM

We were using WS, that was many years ago. We weren't using Cloudflare nor did Cloudflare support websockets. Then at some point we got 250k new WS connections per second, peaking at about 10-15m. Ofc our servers died under that (each connection had to deal with quite some DB reads and writes etc). We were estimating scale of about 300 concurrent connections..

So I got the idea of bundling it all into JS files, since we really didn't need that much of an realtime
Now times have changed and we need realtime again.. But team who made move from WS to bundled JS isn't around anymore, so it's rather interesting digging.. I kinda know what should be there in codebase, but not too sure. It's been over 3y since I worked on that codebase. For all that time it had 5 people on it full-time, so it's been totally rewritten about 2-3 times for sure

Erisa•7/5/23, 11:00 PM

nor did Cloudflare support websockets

dang, that must have been quite some time ago

Erisa•7/5/23, 11:01 PM

blog says they were supported in 2014

McSneakyOP•7/5/23, 11:02 PM

For our use-case we needed (and still need) connection to go to workers, but workers weren't a thing then. Now with durable objects it became possible to move it all to CF

McSneakyOP•7/5/23, 11:06 PM

It's in dev plan, when we get to it is other thing..
Other thing in dev plan is getting really good deal from CF for 10b worker requests to run some AI models on the edge

Erisa•7/5/23, 11:08 PM

by my rough maths, 10 bil workers bundled reqs on paygo plan would be like $5,000 or so

dave•7/5/23, 11:09 PM

that's less than payroll for most folks (in the US anyway)

Erisa•7/5/23, 11:10 PM

indeed

McSneakyOP•7/5/23, 11:12 PM

Most likely as enterprise customer we'd get off from there, but money is tight for business currently. Since market went interesting

McSneakyOP•7/5/23, 11:12 PM

So it hasn't been priority

McSneakyOP•7/5/23, 11:13 PM

I hope once we kill our own small bare-metal server farm, that keeps super legacy stuff running we can redirect that cash flow to fancy CF stuff

Erisa•7/5/23, 11:15 PM

I'm sure our sales team would love a chat when the time comes, if the paygo plan isnt enticing

McSneakyOP•7/5/23, 11:16 PM

You have quite some good fellas in sales team
Can't remember the name of fella who was our sales contact. But he always got us real sweet deals
He also got us hooked in more cool stuff than we had time to implement

dave•7/5/23, 11:16 PM

hopefully you're making money on those 10 billion requests?

Ddave hopefully you're making money on those 10 billion requests?

McSneakyOP•7/5/23, 11:18 PM

We currently make money already based on them. So adding edge-ai on top of that would be just cost at the beginning, until we finish tuning our models
After that can sell it to clients as additional feature for extra cost

erichileman•7/5/23, 11:18 PM

McSneakyOP•7/5/23, 11:18 PM

For how long it would be just a cost, is unknown. That's why business isn't too keen to jump that bandwagon yet + we are in eastern Europe. For that money you can get 2 devs in here

McSneakyOP•7/5/23, 11:43 PM

Jup, that's what we do, charging per 1m requests

McSneakyOP•7/5/23, 11:44 PM

Just increasing that too much would not make customers too happy, unless we can pitch / prove additional value

Chaika•7/6/23, 12:32 AM

it's really not recommended to do so, it's in alpha, the new experimental backend does seem pretty stable, but there's no backups, "time travel" is planned but not available yet, etc

Unsmart•7/6/23, 12:34 AM

DynamoDB and D1 are very very different. A closer alternative on cloudflare is Durable Objects.

Dubz•7/6/23, 4:19 AM

Assuming you can, then most likely? I think it goes into a grace period, so you couldn't do this in one night. It would possibly take a month or longer. If you have domains registered through Cloudflare, it may require you to transfer them out to a different registrar before you can delete the account.

Aah, that's actually interesting idea. Currently hashes are rather random. But could make them kinda
