Enum IvfRoutingMode 

pub enum IvfRoutingMode {
    Auto,
    Flat,
    TwoLevel,
    Hnsw,
}

How an IVF coarse codebook is searched.

This is shared by floating-point and packed-binary dense fields. It only controls centroid routing; vector encoding and the distance metric remain properties of the concrete dense index.

Variants

Auto

Select flat routing for small codebooks and HNSW routing for large codebooks where scanning every centroid would dominate query latency.

Flat

Score every leaf centroid exactly.

TwoLevel

Use a two-level, beam-routed hierarchy over the leaf centroids.

Hnsw

Use an HNSW graph over the global leaf centroids.
