A high performance distributed Graph Database

Primary LanguageC++

Nebula

Nebula is a distributed, scalable, lighting-fast graph database. It is the only solution in the world capable to host graphs with dozens of billions of vertices (nodes) and trillions of edges, while still provides millisecond latency.

Nebula's goal is to provide reading, writing, and computing with high concurrency, low latency for super large scale graphs. Nebula is an open source project and we are looking forward to working with the community to popularize and promote the graph database.

As a graph database, Nebula has these features

  • Symmetrically distributed
  • Highly scalable
  • Fault tolerant
  • Strong data consistency
  • SQL-like query language

How can I contribute

As the team behind Nebula, we fully commit to the community and all-in to the open source project. All the core features are and will be implemented in the open source repository.

We also encourage the community to involve the project. There are a few ways you can contribute:

  • You can download and try Nebula, and provide us feedbacks
  • You can submit your feature requirements and bug reports
  • You can perfectionate documentations
  • You can fix bugs or implement features. More details on how to build the project and submit the Pull Requests click how-to-contribute.

Licensing

Nebula is under Apache 2.0 license, so you can freely download, modify, deploy the source code to meet your needs. You can also freely deploy Nebula 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 Common 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.
