Parent article: Filesystem support for block sizes larger than the page size

Depends how much state, across how many files, but (if I understand correctly) I'm sure object based databases could benefit.

I would want to update part of a file (maybe two or three blocks, across a several-meg (or more) file) and the ability to rewrite just the blocks of interest, then flush a new inode or whatever, changing just those block pointers, would be wonderful.

Maybe we already have that. Maybe it's too complicated (as in multiple people trying to update the same file at the same time ...)

Cheers,
Wol
