Struct HNSWPQIndexParam

pub struct HNSWPQIndexParam {
    pub m: u32,
    pub ef_construction: u32,
    pub nsq: u32,
    pub sample_rate: f64,
}

Fields

m: u32

range [4, 128], neighboring nodes are connected to each node in the HNSW index graph

ef_construction: u32

range [8, 1024], the number of temporary neighbor nodes used during build index

nsq: u32

range [1, dim] the number of quantization subspaces, pq quantization correlation coefficient, and requires NSQ | dim. The larger the NSQ, the finer the quantization

sample_rate: f64

range [0.0f, 1.0f] the sampling rate of k-means and the total number of pq samples, 10000 + (rowCount - 10000)*sampleRate
