That's not surprising though, as DBs usually work best when given raw storage - the features of the filesystem are being duplicated by the DB and thus doing almost twice the work. What seems particularly interesting about Bcachefs is how much it seems to be using database concepts to implement a general filesystem. Ultimately, it seems inevitable that filesystems and databases will converge as they're both supposed to manage data.
