Expand description

Query-global IVF-TQ work shared by every segment: one probe route, one set of TQ LUTs, and one ⟨q̂, centroid⟩ scalar per probed cluster.

Fields§

§quantizer_version: u64§fingerprint: u64

TQ codec fingerprint (carried as codebook_version on disk).

§request_fingerprint: u64§cluster_ids: Arc<[u32]>
