Pages is merging into Workers, but Pages likely exists for a long time as there’s a lot that uses it I would suspect. To help you choose, there’s a matrix here: https://developers.cloudflare.com/workers/static-assets/compatibility-matrix/ (but there’s no time period for merging etc known yet)

Yup, but still - my point was just that “workers execute before cache” that used to always be true now has a nuance

So if I am starting a Svelte project, for instance, I should use Workers and the https://github.com/sveltejs/kit/tree/main/packages/adapter-cloudflare-workers instead of the adapter-cloudflare, which is for Pages with Functions.

But I’d say that’s a good idea (CF docs: https://developers.cloudflare.com/workers/frameworks/framework-guides/svelte/). Keep in mind it is in beta, so maybe some bugs, but as betas go, it’s probably pretty stable.

Chaika•9/30/24, 6:35 PM

not normal cache, it'd just be kv. Still correct to say there's no cache before Workers

AAshley That I do not know 😅

Harold Anderson•9/30/24, 6:36 PM

Thank you. Svelte 5 is a total rewrite of Svelte 4 but is supposed to be backward compatible. However, Svelte 4 is being gently discouraged. Just trying to avoid writing obsolete code from day 1.

AshleyOP•9/30/24, 6:42 PM

I think you can argue this both ways. If we look at how things were before - there was no cache, all requests hit the worker - that’s not quite true now. There is another mechanism now, with static assets, that means your worker won’t be hit. Whether it’s KV or otherwise is an implementation detail, imo.

Chaika•9/30/24, 6:43 PM

You can say not all requests will result in worker invocations sure, still no cache though

Chaika•9/30/24, 6:44 PM

if you wanted to be more specific you could say no cache of worker results but ehh the fact KV internally talks to cache service is an implementation detail

AshleyOP•9/30/24, 6:51 PM

That’s fair, I think this is probably a Cloudflare-specific case where it’s a little cloudy (excuse the pun) - as if I was storing something in KV as part of my Worker, I’d say KV is caching, same as Redis in a non-CF architecture. But with CF having so many caching mechanisms, perhaps it’s better to be explicit and say KV rather than cache for Static Asset workers - thanks for the chat, fun to discuss these things

Chaika•9/30/24, 6:55 PM

I mean to me the root of it is just that even if you use kv in your worker you can't cache your worker result and avoid an invocation. Static Assets are entirely free, kv cache hit or not

AshleyOP•9/30/24, 6:58 PM

I agree, but it's not the same as it was before - before it was all workers, every single request, and that's just the distinction that I think is important/needs to be clear. KV, imo, is a form of cache, so I think it's fair to say that for static assets, they are not invoking your worker, and they are (potentially) being returned from cache (which is KV, so you can't control the cache unlike other cache products). What I was getting at with the cache stuff is within Cloudflare specifically there's a lot of heavy-lifting done by the word cache (tiered, reserve etc.) versus in general software engineering, it's a pretty generic term (e.g. you could cache in memory and you're caching, in say a Rails app)

Chaika•9/30/24, 6:59 PM

yea it's def not same as before. With Pages you could even cache function results (or double cache static) on custom domain if you wanted as well which was interesting

AshleyOP•9/30/24, 7:00 PM

I think there used to be a diagram somewhere but I can't find it that explained all the caches, where they sit, and the order of execution - maybe it was on a blog. If someone has an up-to-date version of that, that'd be mega handy (including this new stuff with static assets workers)

AAshley I think there used to be a diagram somewhere but I can't find it that explained ...

Chaika•9/30/24, 7:00 PM

explained all the caches?

Chaika•9/30/24, 7:01 PM

There's general request flow chart but I've never seen anything about all the caches I don't think

AshleyOP•9/30/24, 7:01 PM

Maybe I dreamt it

Chaika•9/30/24, 7:01 PM

really not that many anyway unless you want to try to get deep into dns cache/workers being kept warm/etc

AshleyOP•9/30/24, 7:02 PM

Do you have a link to that general request flow chart by chance?

Chaika•9/30/24, 7:02 PM

right side of specific dash pages like waf if you have big enough of a screen

AshleyOP•9/30/24, 7:03 PM

Thank you

Chaika•9/30/24, 7:03 PM

https://blog.cloudflare.com/building-cloudflare-on-cloudflare/ there is some other diagrams from blogs like

Chaika•9/30/24, 7:05 PM

oh actually there is flow charts for the tiered caches https://blog.cloudflare.com/introducing-cache-reserve/, if you want to include all of the different types of the normal http caches it gets more complex, like
Local -> Tiered Cache Middle -> Tiered Cache Upper -> Cache Reserve -> Origin
and then if you want to get really complex I believe Cache Reserve lives in Pingora while local (and maybe tiered cache too?) just live in other more local services, one of the reasons why cache api is local only afaik

AshleyOP•9/30/24, 7:07 PM

This is awesome, thank you!

Chaika•9/30/24, 7:10 PM

yea there is a lot of layers of http cache, and the rest is more messy. KV is local/tiered. Workers Cache API is just local. R2 Custom Domains just local too, probably same thing for Pages Custom Domains but I've never checked

Chaika•9/30/24, 7:12 PM

yea might just be a general cf for saas thing

DiamondDragon•9/30/24, 7:21 PM

any chance someone can take a look at this? it was reported before and a fix was deployed so not sure why i am experiencing this issue

Cyb3r-Jak3•10/1/24, 1:08 AM

You can not.
From https://developers.cloudflare.com/workers/platform/limits/#simultaneous-open-connections

Simultaneous Open Connections are measured from the top-level request, meaning any connections open from Workers sharing resources (for example, Workers triggered via Service bindings) will share the simultaneous open connection limit.

Isaac McFadyen•10/1/24, 1:21 AM

I believe (not completely sure but highly likely) that the limit is Cloudflare-wide, meaning it's an underlying limit that is built into the Workers runtime and not a limit that can be easily increased per customer.

Isaac McFadyen•10/1/24, 3:08 AM

Unless you have an Enterprise contract that specially permits them, containerized apps aren't currently available for Workers.

Isaac McFadyen•10/1/24, 3:09 AM

The blog post was more a "here's this internal thing we're testing out now that might eventually come to external customers" and less "you can deploy containers to Workers right now"

BC17•10/1/24, 9:55 AM

Feel I've searched and there's different responses and levels of understanding on cache reserve and tiered caching, especially when workers are considered so I just want to clarify

If I am serving a SSR site with workers and static assets, would the following occur;

I cache HTML via origin headers (Astro.header.set) on a short TTL, 15 minutes for example. Would tiered caching ever be utilised here if it was switched on?
If I switch on cache reserve, would the static assets served from the public and _astro directories ever be served from it?

The cache reserve is so we can persist assets across deployments due to stale HTML referencing old assets - maybe this is less so an issue, but feel we seem to get stung by all hosts in this department so having some sort of persistent storage between deployments is useful
