UnisonDB addresses the challenge of unifying data persistence and real-time streaming for Edge AI and Edge Computing. It targets developers building reactive, local-first distributed systems, offering a log-native database that enables near-instant replication and low-latency responsiveness across numerous edge nodes without complex external pipelines.

How It Works

UnisonDB is a log-native, multi-model database that fuses storage and streaming. It utilizes a B+Tree engine (BoltDB/LMDB) for durable, queryable data and Write-Ahead Logging (WAL) for high-throughput ingest and efficient streaming replication. Every write becomes a durable stream, enabling sub-second fan-out to hundreds of nodes and simplifying distributed application architectures.

Quick Start & Requirements

• Install/Run: Clone the repository, build with go build -o unisondb ./cmd/unisondb, and run ./unisondb --config config.toml replicator. An example HTTP API PUT request is provided.
• Prerequisites: Go toolchain for building. Development section mentions mkcert for local TLS certificate generation.
• Links: Official repository: https://github.com/ankur-anand/unisondb. Documentation includes Getting Started, Configuration, Architecture, API Reference, and Deployment guides.

Highlighted Details

• Multi-Modal Storage: Supports Key-Value, Wide-Column, and Large Objects (LOB).
• WAL-Based Streaming Replication: Achieves sub-second fan-out to 100+ edge replicas, with multi-hop relaying scaling to 10,000+ nodes within seconds.
• Real-Time Notifications: ZeroMQ-based side-car provides sub-millisecond latency change notifications.
• Edge-First Design: Optimized for local-first and distributed edge computing scenarios.
• Performance Claims: Propagates updates across 10,000+ nodes within seconds, even at high write loads, without external brokers.
