Database File System
ozy writes "With all the fuss about searching and Spotlight and WinFS, check out the Database File System a completely different interface for your files, implemented in KDE. There is actually a request for developers to join a project to implement this under GNOME and leave how we use the desktop today behind."
Nobody is sugesting to use such database FS for entire system. Only for specific data (f.e. user documents) - not entire system (binaries, libraries etc.) where such performance matters. Well in fact it will improve performance since right now applications that need such indexing (best examples are apps for organizing music (like iTunes) or digital pictures colections (like Adobe Photo Album or Google Picasa)) do it themselves which probably is not the fastest way and is not unified across the system. Now for *some* applications such view on files that lets you query for specific files/objects operating on query results rather as directories of files have much benefit. But it is only for organizing data, and in limited scope (as I've said - digital music, photography, probably some other fields). I don't really belive that this would seed up searching for office documents over LAN or smth. - when somebodys documents are in mess DB-FS won't change anything as the documents probably lack metadata, proper naming anyway.
For those of you that have not yet looked at the Mac OS X (Tiger) preview and WWDC web cast, the new spotlight technology built into the next version of Mac OS X looks very much like a fully integrated database file system. And it's incredibly fast. Go check it out!. Note: QuickTime required. Mplayer may work for us Linux heads but I haven't tried it.
