Actually, I would take that as an reason not to have database
directories.
If the number of files becomes a concern, we would need some kind of a
hashing algorithm to disperse them appropriately. The database
directory would just get in the way without really adding anything. Is
1000 per files as a directory limit still the rule of thumb for a limit?
A single TB sized db would start to run into those types of limits.
