P: Catalogs should not include LUT to manage catalog size

Hello,

I've been using a RNI profile for a couple years now and these last couple months I've (re)edited a lot of my keepers using it. The problem is that the catalog size has easily doubled or tripled because of that. I guess it's the profile that's causing it: it has a custom color table inside and so when I save the external .XMP associated with a RAW file, it is around 240kb, compared to the 10kb or less of a Lr profile sidecar. That adds 1mb for each 4 images I edit, 1gb for each 4000 processed images.

I don't know how Lr works in the insides, but it looks like instead of linking the image file to a profile file, it embeds or write the profile for each image, every time, resulting in bigger and bigger catalog files.

Is there any workaround or do I just sit and watch my catalog grow? It currently is 7,5gb after deleting History.

Thanks!
