[Feature] Separate thumbs storage location by quality

I have searched the existing feature requests, both open and closed, to make sure this is not a duplicate request.

• Yes

The feature

We now have 3 qualities of thumbs:

• thumbnail
• preview
• fullsize

Users may want to use flash storage for some but not all of these files. For example, on my system, the thumbnail WEBPs take 3 GB, while the preview JPEGs take 60 GB. Moving the thumbnails to an SSD would greatly improve the timeline experience.

Proposed solution: migrate thumbs to 3 subfolders:

• thumbs/thumbnail/<user UUIDs>
• thumbs/preview/<user UUIDs>
• thumbs/fullsize/<user UUIDs>

In this way users can mount varying storage to the subfolders and mix flash and HDD storage. This shouldn't be a breaking change, and we can use the Storage Migration job.

This is great!

I would love for this to be implemented to allow my unsaid server to upload thumbnails much quicker to the mobile app while I'm not home.

This PR doesn't separate preview and fullsize thumbs 👎

[mmomjian]

There has been extensive discussion on discord. at this time the sizes are not stable enough to split beyond thumbs

Yes, that is on purpose. First, I'm not sure why you'd want preview and fullsize separated. But ignoring that point, it's actually because the devs haven't decided on finalizing those items.
