A distributed, scalable, lightning-fast graph database
Please note that this repo is only for Nebula Graph v1.*.*.
From v2.*.*, which was already GA in 2021 April, Nebula Graph's core codebases are nebula-graph, nebula-common and nebula-storage, it's recommended to start from the repo: nebula-graph.
Nebula Graph is an open-source graph database capable of hosting super large-scale graphs with billions of vertices (nodes) and trillions of edges, with milliseconds of latency. It delivers enterprise-grade high performance to simplify the most complex data sets imaginable into meaningful and useful information.
Below is the architecture of Nebula Graph:
Compared with other graph database solutions, Nebula Graph has the following advantages:
- Symmetrically distributed
- Storage and computing separation
- Horizontal scalability
- Strong data consistency by RAFT protocol
- SQL-like query language
- Role-based access control for higher level security
