Metadata about a collection for query planning.
Fields§
§name: String§engine: EngineType§columns: Vec<ColumnInfo>§primary_key: Option<String>§has_auto_tier: bool§indexes: Vec<IndexSpec>Secondary indexes available for planner rewrites. Populated by the
catalog adapter from StoredCollection.indexes. Building entries
are included so the planner can see them but MUST be skipped when
choosing an index lookup — only Ready indexes back query rewrites.
bitemporal: boolWhen true, this collection stores every write as an immutable
version keyed by system_from_ms. Enables FOR SYSTEM_TIME AS OF
and FOR VALID_TIME queries. Only meaningful for document engines
today; other engines ignore this flag.
primary: PrimaryEnginePrimary engine hint from the catalog.
vector_primary: Option<VectorPrimaryConfig>Vector-primary configuration. Some only when
primary == PrimaryEngine::Vector.
