🔬 Log-Structured Merge-Tree (LSM) & Write-Amplification Research

BadgerDB (dgraph-io/badger): An influential key-value store built around the concepts of the academic paper “WiscKey: Separating Keys from Values in SSD-conscious Storage”. It research-validates how moving heavy values into a dedicated log while keeping small keys in an LSM-Tree minimizes write amplification and extends SSD lifespans.

It integrates RocksDB directly with physical Zoned Namespaces (ZNS) on modern NVMe SSDs, bypassing the Linux file system entirely to test how atomic hardware zone allocations improve NoSQL write performance.
