Architecturevector-rag / parallel graph traversal vector DB
DetailsEpsilla leverages parallel graph traversal algorithms pioneered by its founding team (ex-TigerGraph engineers) to achieve claimed 10x faster vector search over comparable HNSW implementations. The open-source core provides low-latency ANN search across billions of vectors; the cloud service adds an AI agent builder with knowledge-base connectors. Supports hybrid search with metadata filtering.
