Re: Changes in SQL backend design

Hello Jan,

Sorry for the delay; but reading the thread "Severe performance issues with
large directories" I just remembered that the backend has a little bit of a
problem with big directories - storage overhead.

Do you see any way to split directories into a series of blocks (like files
are done), and when changing only a few of the files using pointers to the
unmodified blocks of the old directory?

I don't propose a real delta design - that was too slow, IIRC.
Just re-use of directory blocks; that shouldn't bring any performance issues.

Is there some way to do that? Perhaps multiple "." entries in a directory,
which just point to other parts?

Regards,

Phil
