Overview
NebulaGraph is a graph database written in C++ that separates storage from compute and scales horizontally. It uses the Raft protocol for strong consistency, accepts an OpenCypher-compatible query language, and has role-based access control. The README points to its docs for install and quick start.
Who it is for: Engineers self-hosting a distributed graph store for large connected datasets
Strengths
- Storage and compute are separate, so each layer scales horizontally on its own
- Raft consensus gives strong data consistency across replicas
- OpenCypher-compatible query language
- Apache-2.0 license allows use as a SaaS backend
Weaknesses
- Multi-component distributed deployment is heavier than single-binary databases
- README lists build from source or AWS cloud; no Docker or compose files detected
- Last release is 2024-05-17, though commits continue
- Not an AI or LLM tool itself, so fit for AI starters is indirect
What it needs
- no GPU
- Docker
