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: bool

When 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: PrimaryEngine

Primary engine hint from the catalog.

vector_primary: Option<VectorPrimaryConfig>

Vector-primary configuration. Some only when primary == PrimaryEngine::Vector.

partition_strategy: PartitionStrategy

How this collection’s rows are distributed across vShards.

Authoritative per-collection partition metadata. Future routing layers read this instead of inferring distribution from engine type.
