説明
Problem Statement
Lance rust dataset has the capability of querying over vector space, via Scannner::nearest(..), we should expose this to DuckDB via its extension mechanism.
For example, a potential implementation could be a duckdb table function lance_nearest
SELECT id, col
FROM lance_nearest("table", "vector_column", "query", top_k)
WHERE city = 'SF' and day = "02-03-2023"
