Not really. This is more like SQLite or DuckDB for vector databases (on disk.) Chroma is more like redis for vector databases (in memory.)

We have seen similar products in the olap space, as well, ie. Clickhouse local.

Chroma used DuckDB at some point, might not be the case anymore though

Doesn't DuckDB already do vector search?

They do have an extension for vector similarity search (https://duckdb.org/docs/extensions/vss).

But Milvius might propose more features, as they have been in this specific space for longer.
