Specific characteristics

Nebula Graph is a truly distributed, linearly scalable, lightning-fast graph database, while still providing millisecond latency, high availability and data security. Key features include:

  1. Open source. We are continuing to collaborate with the community to prepare, populorize the graph database. 
  2. High performance. Nebula Graph provides low latency read and write, while still maintaining high throughput. Nebula Graph has published its benchmark report based on the LDBC social networking dataset for k-hop read performance in terms of latency and throughput. See the report for details.
  3. SQL-like query language. Nebula Grap's SQL-like query language, nGQL, is easy to understand and powerful enough to meet complex business needs.
  4. Highly secured graph database. Nebula Graph only allows authenticated access via role-based access control.
  5. Horizontal and vertical scalability. With a shared-nothing distributed architecture, Nebula Graph offers linear scalability.
  6. Extensible. Nebula Graph supports multiple storage engine types and multiple computing frameworks.
  7. Production ready. Large Internet companies like JD Digit (NASDAQ:JD), Meituan (3690.HK), and Xiaohongshu (RED) have deployed Nebula Graph in production environments. They chose Nebula Graph for some common reasons.
  8. Highly available. With horizontal scalability and a snapshot feature, Nebula Graph guarantees high availability even in case of failures.
Competitive advantages

Nebula Graph boasts the world's only graph database solution that is able to host graphs with dozens of billions of vertices and trillions of edges, while still providing millisecond latency, high availability and data security.

Typical application scenarios
