I know that nowadays we all got huge hard disk drives, but what about a “single instance filter”?
The idea came when I was explaining to my bosses about BFS (and was talking about storage in general) and they loved the idea of a database-like filesystem and all the possibilities.
Ok, ok, media files tend to be substancially different and big, so it wouldn’t be very handy (at least, not at a first sight), but for a huge ammount of small files, source-code editing and other uses (er… file servers) and so would be nice. Again: I know that Haiku isn’t meant to be a server OS neither a development box, but well… it’s a topic, so let’s discuss it
As an option (selectable, maybe), would be interesting to have something similar to this? Not exactly a FS filter (add-on or simmilar), maybe a part of the BFS driver or even another idea.
I was thinking about the implementation… it might be something like this:
- Equal files. Just create anoter reference to it. Independent attributes and so. The main idea, nothing complicated;
- Slightly different files. Two option then: create a copy of the file or just a image with the differences or yet another crazy squeme that someone more clever than might think.
The problem is that this process introduces some wait while manipulating files and BFS is known to be fast and this gap could compromise system responsiveness to applications that need the hard disk contantly or other situations. Well, something to the programming team 8)
Maybe I’m thinking some insanities here but… what you say?
