Struct PhysicalVectorSimilarityScan

pub struct PhysicalVectorSimilarityScan {
    pub index_name: String,
    pub index_id: u64,

Expand description

Physical operator for vector similarity search using an HNSW index.

Searches the VectorIndexTable for the top-K nearest neighbours and looks up the corresponding rows from the NodeTable to produce output columns including a distance column.
