What NebulaGraph is

NebulaGraph is a distributed graph database for storing and querying complex connected data. It is designed for scalability and performance, and NebulaGraph says it can handle graphs with trillions of edges and vertices. It supports nGQL and openCypher compatibility; native ISO-GQL support is available in Enterprise v5.0. Native vector search combines graph structures with unstructured data. Deployment choices include on-premises, public cloud and hybrid environments, and NebulaGraph Cloud can run clusters on Microsoft Azure, AWS and Google Cloud Platform. Java, Python, C++ and Go clients, plus Spark and Flink connectors, are listed among its ecosystem tools. NebulaGraph Studio is a browser-based tool for schema creation, data import, query writing and graph exploration. Cloud security features include Private Link and role-based access to graph spaces; availability uses Raft-based redundant backups across server rooms in the same city. Snapshots support point-in-time restoration. The free Apache 2.0 open-source edition covers a subset of core features. A 14-day Cloud trial includes one instance with 2 vCPUs, 4 GB RAM and 10 GB storage, without requiring payment information.
