P: Allow Catalog to be stored on a networked drive.

I wonder if it would be possible to implemented localized "cloud-lets". i.e. take advantage of Carousel/Cloud software technology fitted for local net.

Yes, I know, and I'm honestly trying not to be too negative here, but Carousel will never be the solution to this problem. I shot 6 GB of images this afternoon, 6 GB yesterday, and 30 GB on Thursday. I need a solution that allows me to work from my laptop or my desktop across my LAN. Uploading all that data to a cloud services to work from is simply not feasible.

Remember, I said "It's the start..."

Yikes. Carousel doesn't even come close to addressing the needs of this feature request. It's jpg only and it's a separate program. Either of those are deal breakers. Together....

Yes, that's my experience too. Performance isn't very good, eventhough I am using a N network. Plugging in the external drive helps a lot, but having the files on an internal hard drive... (esp. if it is fast...). Only do it if you really have to, and you could try to (automatically?) sync the catalog file (+ thumbnails perhaps), just make sure the location of the catalog as well as the location of the photos stays the same on both computers. And yeah, having the files on the computer you usually work with helps too, since otherwise the loading of the RAW files will take a while too (depending on the network of course, with a 1 Gbit connection it might not be that much of an issue anymore).

Have you guys looked at Adobe Carousel? It's the start of multi-user, multi-computer, multi-device workflow.

feature request for this site: ability to "gold-star" comments as well as original replies 😉

SQLite makes use of frequent, small I/O operations, and the performance of those can get killed by network latency (time to send a single packet). Wireless networks, even N networks, have much higher latency than wired networks, and thus I'd bet good money that LR catalog performance would suffer over an N network. Wifi N is reasonably good at video streaming, because packet latency doesn't matter, only total throughput (bandwidth).

Photshop Elements (since v6) also uses SQLite for its catalogs, and I tried an experiment running it over a 100Mb Wifi network. Performance was horrible.

Thank you! - I wonder how it would be with a good solid "n"-type wi-fi connection (designed for wireless HD video streaming...) - dunno how quick those are for frequent little tidbits, like misc quick-accesses to catalog...
