NebulaGraph has been widely used for social media, recommendation systems, knowledge graphs, security, capital flows, AI, etc. See [our users](https://nebula-graph.io/cases). The following lists some of **NebulaGraph** features: * 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 * Different types of graph analytics algorithms The following figure shows the architecture of the **NebulaGraph** core.  Learn more on [NebulaGraph website](https://nebula-graph.io/). <!-- ## Notice of Release NebulaGraph used to be split into three repositories: [Nebula-Graph](https://github.com/vesoft-inc/nebula-graph), [Nebula-Storage,](https://github.com/vesoft-inc/nebula-storage) and [Nebula-Common](https://github.com/vesoft-inc/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](https://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/. NebulaGraph 1.x is not actively maintained. Please move to NebulaGraph 2.x. <br/> The data format, rpc protocols, clients, etc. are not compatible between NebulaGraph v1.x and v2.x, but we do offer [upgrade guide](https://docs.nebula-graph.io/2.5.0/4.deployment-and-installation/3.upgrade-nebula-graph/upgrade-nebula-graph-to-250/). To use the stable release, see [NebulaGraph 1.0](https://github.com/vesoft-inc/nebula). ## Roadmap See our [Roadmap](https://github.com/vesoft-inc/nebula/wiki/Nebula-Graph-Roadmap-2020) for what's coming soon in **NebulaGraph**. --> ## Quick start Read the [getting started](https://docs.nebula-graph.io/3.8.0/2.quick-start/1.quick-start-workflow/) docs for a quick start. ## Using NebulaGraph NebulaGraph is a distributed graph database with multiple components.
