lsmdb

A persistent, crash-safe key-value storage engine built from scratch in Rust on an LSM-Tree architecture. Implements a Write-Ahead Log, Bloom Filters, LRU block cache, and a custom arena-allocated SkipList MemTable. Published on crates.io as a library and CLI binary.

I built this to understand how storage engines fail under pressure. That understanding directly informs how I reason about data tier architecture and I/O latency in production infrastructure.
