Episode notes
Columnar Design Powers Large Single‑Node Graphs
- Kuzu is an embeddable, columnar graph database built from academic research and OLAP principles.
- It combines columnar storage, vectorization, factorization, and novel join algorithms to scale to billions of nodes on one machine.
Scalability Focused On Single‑Node Growth
- Kuzu defines scalability as seamless growth on a single machine by pushing operations to disk and using temporary files for intermediate results.
- This lets users handle hundreds of gigabytes to terabytes and billions of edges without changing workflows.
Combine Vector And Graph Retrieval
- Combine vector and graph retrieval to give LLMs better context in RAG systems.
- Use Kuzu's built‑in vector index alongside its graph retrieval for richer AI retrieval layers.
