Fields

name: String

graph index name (e.g., “news”)

dim: u32

vector dimensionality

m: u32

HNSW M parameter

m_max0: u32

HNSW max neighbors at layer 0

ef_construction: u32

HNSW ef_construction

ef_search: u32

HNSW ef_search

metric: String

“l2”, “cosine”, “ip”

edge_segment_duration: u64

time segment for edge partitioning (ms)

backend: String

“disk_hnsw” or “spfresh” (default: “spfresh”)

default_decay_half_life_ms: u64

Per-graph default recency half-life (ms) for graph_rag_search recency decay. 0 = use the server ~180d constant. A GraphRagSearch sending decay_half_life_ms == 0 resolves to this persisted value when set.

quantizer: String

In-list vector quantizer: “sq8”, “pq”, or “rabitq”. “” = backend default (disk_hnsw -> sq8, spfresh -> pq), which is byte-identical to pre-field behavior. Part of the graph’s schema identity: a re-create with a different quantizer is rejected (change it via an explicit rebuild).

shared_sub_plus1: u32

P5b: shared-CF sub-index id (+1 encoding: 0 = dedicated CF, N = sub N-1) so the field is optional without proto3 optional syntax.

cf_id_hint: u32

The metadata-registry cf_id this graph is registered under. A data node creates its physical CF at exactly this id, keeping the node-local physical id space and the cluster-wide metadata space identical — a replicated write batch names its CF by number, so letting each node pick its own would wedge apply or land rows in the wrong column family.

The gateway reserves the id (MetadataOp::ReserveCfId) before fanning out, so this is authoritative rather than advisory. 0 means the reservation could not be obtained; the node then allocates locally and the applier’s id translation covers the difference.
