Dwaal

Dwaal is a lightweight, local key-value store for Node.js that enables shared, persisted data across multiple processes on the same machine. It uses Unix sockets for inter-process communication and elects a leader process to manage an in-memory map, with lazy atomic writes (every ~500ms) to disk. Version 0.2.0 is the current stable release; it requires Node >=6.0.0 and is suitable for small-scale, local coordination tasks. Unlike Redis or SQLite, Dwaal is process-embedded and does not require a separate server.
