[digiKam-users] Digikam in low latency networks

[woenx]

Ok, yes, before you tell me, I know Digikam is not meant to be used with
network storage units.

Anyway, I just wanted to check of anyone else has experienced this. I am out
of my country for a few months. I have Digikam 6.0 in my computer, with
local databases (in a m.2 ssd drive) and I can access my picture collection
remotely (either using sshfs or though a VPN).

The internet speed between the two hosts is not great, but not terrible
either (~50mbps). However, digikam takes ages to scan the collection for new
files. Something that over a local network should take less than 5 minutes,
it can take more than 12 hours over internet.

I realised that it is likely not a problem of the internet speed, but of the
latency, which is ~100ms in this case.

Is there any way to circumvent this problem and make it usable over an
internet connection?

It is allowable to have the photos stored on a drive connected over a
network connection. What is very heavily discouraged is using an sqlite
database over a network connection.

But your database is local, so this is OK.

That's quite a problem.

Turn off 'Scan for new files on startup'?

Well, yes, I could disable the scanning for new pictures, but that would
defeat the purpose, since I have a shared photo library with my family and I
use Digikam to check for new pictures that they may have uploaded to the
shared storage.

(Btw, what about a possible feature to display the last 100 or 200 imported
pictures?)

What would be really nice is if Digikam could use a file-watcher to look for additional photos, so that new albums or folders could be added/scanned without having to scan the entire collection. I have 20k pictures on my laptop, and 400k on the NAS, and to run even a local scan to add 10 new photos on the laptop takes nearly half an hour.
