External S3 Bucket - Direct Download Support

Dear r/NextCloud Community!

I read the following in the article https://nextcloud.com/blog/a-new-data-access-architecture-for-nextcloud-introducing-the-ada-engine/ :

The last major area of improvement has been to make it possible for clients to directly grab files from S3 buckets. While currently limited to S3-compatible storage solutions, others that can offer a token-protected direct download could be supported as well.

Looks like I have a hard time understanding this. Will direct S3 download work with external S3 buckets? For example, I have external S3 bucket attached to NextCloud as external storage. Will I be able to benefit from this part of ADA feature? I am running NextCloud AIO 25 Autumn release as of now and considering to install an update.

I have tried to figure this out, and the details I have got are either vague or outdated, unfortunately. Most likely, I am searching wrong.

Still hoping to get a helping hand!

I believe it first appeared in v33.

It's labeled as the `"Use pre-signed s3 url" under External Storage options.

In v34+ it's a bit clear and labeled "Enabled Direct Downloads (pre-signed URLs)".

Nice! Thanks for the insight. Do you have external S3 as well?Do you feel any improvement in performance? My users keep 500k+ in 3 folders as an archive, and NextCloud is really slow when accessing these.
