Jeff Layton talks to Valerie(周嘉玲 ) Aurora, file system developer and open source evangelist, about a wide range of subjects including her background in file systems, ChunkFS, the Union file system and how the developer ecosystem can chip in.
JL From your vantage point what do you see for the future of file systems for Linux beyond perhaps btrfs and ext4?
VA Wow! I hadn’t even thought about beyond the upcoming generation of file systems - I’m just glad there is one at all, since it wasn’t at all obvious there would be back in 2006. With regard to local file systems, I think btrfs is flexible enough to handle any projected hardware changes for the next decade, both in performance and capacity - in other words, SSDs and truly enormous quantities of storage. I also think we may see more flash-based devices exporting access to the hardware directly as the SSD market commoditizes, in which case LogFS and NILFS become even more interesting, perhaps as part of an open source layer that can integrate tightly with other Linux file systems. On the parallel, distributed file system front, I’m keeping an eye on . The architect, Sage Weil, really knows his stuff and spent several years getting the design right. On the single-writer/many-reader optimization side of distributed file systems, is super awesome if you can get over the requirement for btrfs as the local file system (and you should).
