NebulaGraph is a high-performance distributed graph database built for extreme scale. While primarily focused on graph workloads, it's increasingly used in AI applications that require both graph relationships and modern data processing capabilities.
Tencent Cloud Security team tests showed that while Neo4j outperformed NebulaGraph slightly with smaller datasets, NebulaGraph proved significantly faster with larger datasets. For three graph queries, NebulaGraph shows clearly better performance compared to Neo4j and HugeGraph.
While not a traditional vector database, NebulaGraph is used in AI applications requiring graph-based reasoning and can be combined with vector databases for hybrid AI systems.
Provides clients for multiple languages and integrates with data processing frameworks. Growing ecosystem for AI applications.
