I'm curious what advantages there are in building compression into the database itself, rather than using filesystem-based compression.
I see ZFS articles[1] discuss how enabling compression improves performance with ZFS; for Linux, Btrfs has compression features as well[2]; and on Windows NTFS seems to too.
