P: AI blob storage size should be limited and automatically cleaned up (like previews)

[thomas5CED]

As discussed in the other thread, LrC 14.4 will store AI denoise/super resolution data in .lrcat-data. This storage seems to be permanent: once AI denoise is enabled for a photo the blob will be stored indefinitely.

The proposal is to limit the amount of AI blobs stored in .lrcat-data by some threshold size and automatically clean up old blobs. If a user opens a photo with a deleted blob again, it needs to be recomputed by running AI denoise again. So this basically trades storage space for additional processing.

I know that this means that opening a photo with a missing blob the first time will result in a significant delay. Users might still want this behavior. Standard size preview generation could use the non-AI-enhanced version of the photo since AI enhancements (except adaptive color profile) are probably not visible on small previews anyway.

This would make AI blobs work the same way was preview storage works.

I like the idea of managing denoise data in the catalog like previews, giving users the option of pruning older, unused denoise data to save on catalog-folder space, at the expense of having to Update AI Settings if you want to export or edit the photo. This would help people who keep their catalogs on internal laptop drives with limited space.

(By "denoise" I mean everything in the Develop > Detail panel -- Denoise, Raw Details, and Super Resolution.)

"once AI denoise is enabled for a photo the blob will be stored indefinitely."

If you remove the photo from the catalog, the denoise data will disappear after you do File > Optimize Catalog.

Alternatively, if you clear the Develop History step for Denoise on a photo, the denoise data will disappear after doing File > Optimize Catalog.

A good one would be an option to remove Denoise data from lrcat-data files upon request. Often, if not always, we don't need to save this data forever, as it's easy to regenerate it.

Backups are a pain in the ass now. My lrcat-data file is about 100GB of denoise data that I don't need anymore, and I can't delete. Precious SSD/HD space is also lost.

Please Adobe!! Do something.

Thanks

We need something to manage the absurd size of lrcat-data files. We're using Denoise, but we don't need to archive it forever, it's something that can easily be (batch or not) regenerated if needed. Backups are gigantic now (mine is way above 100GB!!) and precious SSD/HD space is wasted. We need an option to batch remove Denoise data from folders, selection, catalogs, whatever. Simply going back in history and delete everything after denoise is NOT an option if you have done something to images (and always is the case) after the Denoise, and it's not really possible on hundreds, thousands or even (in my case) 200,000 and more photos. Adobe! Please help!!
