What is it?

NebulaGraph is a graph database designed to store and query large volumes of connected data, such as social relationships, recommendation graphs, and knowledge graphs. It uses a storage and computing separated architecture, so storage and query capacity can be scaled out by adding nodes.

The database uses the RAFT protocol for strong data consistency and supports role-based access control. Queries are written in an OpenCypher-compatible language, and the project includes several graph analytics algorithms.

The project offers a downloadable build, a cloud option on AWS, and a set of ecosystem tools for management and monitoring. Its documentation covers installation, a quick start, and contribution guidelines.
