TigerVector: Supporting Vector Search in Graph Databases for Advanced RAGs
Summary: TigerVector integrates vector search with TigerGraph's MPP, extends vertex embeddings, and adds an index framework. GSQL adds vector type expressions for hybrid queries; results show performance vs Neo4j/Neptune/Milvus in TigerGraph v4.2 (Dec 2024). (summarized by gpt-5-nano on Feb 09 2026)
