Microsoft Research · Talk · 1 h 1 min · 2016 · YouTube title: BetrFS: A Right-Optimized Write-Optimized File System
Why it's here
HN points to it as a solid, if long, introduction to B-epsilon trees and why BetrFS is built the way it is.
What it covers
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.
