BetrFS: A Right-Optimized Write-Optimized File System
Microsoft Research
A Microsoft Research talk on BetrFS, a file system built on B-epsilon trees, a write-optimized data structure. It covers WODS such as LSM-trees, how to design a file system around them, and benchmark wins over ext4 and xfs.
HN points to it as a solid, if long, introduction to B-epsilon trees and why BetrFS is built the way it is.
