Response with detailed collection configuration.

Fields

name: String

Collection name.

dimension: usize

Vector dimension (0 for metadata-only collections).

metric: String

Distance metric.

storage_mode: String

Storage mode (full, sq8, binary, pq).

point_count: usize

Number of points in the collection.

metadata_only: bool

Whether this is a metadata-only collection.

graph_schema: Option<Value>

Graph schema (if this is a graph collection).

embedding_dimension: Option<usize>

Embedding dimension for graph node vectors.

schema_version: u32

On-disk schema version. Increments when the persisted config.json format changes in a way older VelesDB versions cannot safely read.

pq_rescore_oversampling: Option<u32>

PQ rescore oversampling factor. See CollectionConfig for the semantics of None, Some(0), and Some(n > 0).

hnsw_params: Option<Value>

Persisted HNSW parameters (M, ef_construction, etc.) when customised at create time. None means the defaults inferred from the collection dimension are in use.

deferred_indexing: Option<Value>

Deferred indexing configuration (US-366) — None when the feature is disabled for this collection.

async_index_builder: Option<Value>

Async index builder configuration (Issue #488) — None when the feature is disabled for this collection.
