As i said, i don't use exif metadata, i use only .xmp sidecars.
I have no exif metadata. If i have to import images with exif metadata,
i delete them with exiftool before.
I tried to use sidecars for read-only on each computer, no change. May
be I'm wrong: "normally", database on computer 'B' has to know that some
.xmp have changed for XCF files (same issue with .mp4), but it doesn't
happen.
  I fear that I have to use only one mariadb database and only one
images folder, for two computers, on an external drive.
I should like to avoid this solution...
