A distributed, scalable, lightning-fast graph database
NebulaGraph is an open-source graph database capable of hosting super large-scale graphs with dozens of billions of vertices (nodes) and trillions of edges, with milliseconds of latency.
Trusted and contributed by users, the NebulaGraph community comes with a rich open-source ecosystem. And it has been widely used for social media, recommendation systems, knowledge graphs, security, capital flows, AI, etc, see our users.
Compared with other graph database solutions, NebulaGraph has the following advantages:
- Symmetrically distributed
- Storage and computing separation
- Horizontal scalability
- Strong data consistency by RAFT protocol
- OpenCypher-compatible query language
- Role-based access control for higher-level security
NebulaGraph used to be split into three repositories: Nebula-Graph, Nebula-Storage, and Nebula-Common for versions between v2.0.0 and v2.5.x, which will be archived.
The one and only codebase of NebulaGraph is now github.com/vesoft-inc/nebula, as it's back to mono-repo since v2.6.0.
Please check the latest release via the documentation: https://docs.nebula-graph.io/.
