yup, just confirming the alternatives you proposed Bennett

@fenos @inian
Quick question to be confirmed, does it mean upload("same_url_as_before") now will automatically burst the cache? If someone else access the resource via same_url_as_before without any versioning param, and still benefit from the cache and get latest data if cache burst from our side.
It's very common people wouldn't include a param when accessing a public resource, if people have to keep up with the version control/param to the lastest, then we completely give up the benefit of CDN.
Assume we have the url with the latest versioning from the server, it will just create a double round trip issue (need to wait for the url version from the server and then call grab data via that url), this will be more slow.

Hey @bennettdams,

There are a few ways to do this.

• Cache bust by adding the version parameter to your Supabase URL. By changing the version tag there, you can bust the CDN cache.
• You can set a shorter cacheControl header when you upload, so that the CDN checks for a new asset every max-age seconds. By default this is set to one hour, and you can set a shorter time there
• You can also bypass the cache by renaming the file itself instead of adding a version query parameter to the URL

We are looking to build a smarter cache here (eg. clearing the cache for the URL automatically when you use upsert), but that's not in the immediate roadmap.

@inian Thanks! Just to be sure: You didn't list a new option in your comment that I hadn't already mentioned in my post, right?

That would be a really good feature to avoid workarounds to bust the cache on file update! +1

This is now been implemented by the Smart-CDN caching

The smart CDN is restricted to only paid users so...🥲
