[Discuss] EXT2 Maximum number of directories?

[Noel Burton-Krahn]

Just a thought:  If you want to use something like a filesystem with 1000's 
of files as a database, have you considered implementing your own filesystem 
driver with a database backend?

FUSE (http://fuse.sourceforge.net/) lets you write user-space filesystem 
drivers.  You can even implement a filesystem driver in Python. I'm thinking 
you could implement  a filesystem that stores your 1000's of files in a 
single SQLite db.  How about that?  It would be very fast, have low overhead 
per file, and still have nice filesystem-like semantics.

RelFS (http://relfs.sourceforge.net/) looks like something along those 
lines.
