A distributed, scalable, lightning-fast graph database

What is Nebula Graph?

Nebula Graph 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.

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
  • OpenCypher-compatible query language
  • Role-based access control for higher level security

The Nebula Graph team is glad to announce the Nebula Graph 2.0.0 GA. This is a brand new start with several important updates, and more of them are on the way. Welcome to join us.

Contributing

Contributions are warmly welcomed and greatly appreciated. And here are a few ways you can contribute:

Licensing

Nebula Graph is under Apache 2.0 license, so you can freely download, modify, and deploy the source code to meet your needs. You can also freely deploy Nebula Graph as a back-end service to support your SaaS deployment.

In order to prevent cloud providers monetizing from the project without contributing back, we added Commons Clause 1.0 to the project. As mentioned above, we fully commit to the open source community. We would love to hear your thoughts on the licensing model and are willing to make it more suitable for the community.
