The article introduces Bε-trees, a write-optimized variant of B-trees designed to reduce write amplification by deferring and batching updates. It serves as the theoretical foundation for the GEFS (Good Enough File System), aiming to make B-tree-based file systems more efficient for write-heavy workloads.
Background
Bε-trees are a class of write-optimized tree structures that combine elements of B-trees and log-structured merge (LSM) trees to minimize write amplification while maintaining reasonable read performance.
