LiteStash (Rust)

High-performance key-value store using SQLite static lock sharding.

This is the native Rust client for the LiteStash database. It acts as a high-performance Host that drives the litestash-engine storage appliance via a strictly typed MessagePack protocol.

⚠️ Status: Pre-Alpha / Namespace Reservation This crate is currently being architected. The API below is provisional.

Architecture

LiteStash uses Application-Side Static Lock Sharding.

1. The Client (Rust) determines the routing topology (hashing keys to specific shard files).
2. The Engine (Python/Native Binary) manages the ACID persistence via SQLAlchemy/SQLite.
3. The Bridge communicates via Standard I/O using binary MessagePack frames.

Installation

cargo add litestash
