I don't have any other real use case for bucket per org other than easy bucket mirroring, backup and maybe migration from shared hosting to on premises.

I didn't think of using different prefixes for different media usages. We for example would then use thumbnail/originating_file_uuid.png and poster/originating_file_uuid.png.

How would you handle uploaded media then?

Something to the effect of my_app/profile_images/org_id/user_id/uuid_thumb.png uuid_large.png uuid_original.png can work.

Then in your app, you can have a way of specifying which version of the file you'd like to reference, for example:

`user.avatar.large -> '<path>/uuid_large.png'`

Not sure if that helps?

The problem with that is that the originally uploaded filename is lost. At least without storing it in a separate database.

I could shorten the key by moving the sha512sum from the url to a CHECKSUM file.

org/file_uuid/original/original_filename.png CHECKSUM org/file_uuid/thumb/160x90.png 48x48.png org/file_uuid/poster/1k.png 2k.png org/file_uuid/other/

Correct, I have no need for the original filename in most cases. If I did want this info, for example if I was building a file browser type thing (ala dropbox), then sure I'd keep that in the db.

Personally I'm uploading directly from the browser to S3 using presigned URL's. All files get uploaded to a /tmp directory in my bucket. This bucket is configured so that all files in /tmp are deleted after 1 day (to remove any unsaved uploads). When a form is submitted, I pass the key to the temporary file in the form (via e.g <input type="hidden" name="s3_key">) and create the associated database record. I then move the file from its temporary location to its permanent one upon saving said record.

Feel free to email me to continue this discussion - email address is on my profile.

Sure, but that's a tradeoff nearly every website accepts because they just need the image itself. If you do want to preserve the original filename, is there a reason for not just keeping it in a database?

I'd like to have these systems as decoupled as possible or at least have some meaningful information without a dependency on an external datastore. This might be just me being paranoid and overthinking it but after having to deal with a nasty monolith of an application for the last couple of years and finally convincing the rest that we need to change if we want to be able to expand I want to do it right.
