Kuzu don't support incremental indexing on the vectors. The vector index is completely separate and decoupled from the graph.

I.e: You have to re-index all of the vectors when you make an update to them.

Firstly congratulations on your effort.

How does the graph component of your database perform compared to Kuzu? Do you have any benchmarks.

For RAG I've tried Qdrant, Meilisearch, and Kuzu. At the moment I wouldn't consider HelixDB because of HelixQL. Wondering why you didn't use OpenCypher?

At the moment you have this system which is aimed to support AI/LLM systems but by creating HelixQL you do not have an AI coding friendly query language.

With OpenCypher even older cheap models can generate queries. Or maybe some GraphQL layer.
