Fields

create_sql: String

Parse-able SQL that defines this table.

global_id: GlobalId

GlobalId used to reference this index from outside the catalog, e.g. compute.

on: GlobalId

The GlobalId this Index is on.

keys: Arc<[MirScalarExpr]>

Keys of the index.

conn_id: Option<ConnectionId>

If created in the TEMPORARY schema, the ConnectionId for that session.

resolved_ids: ResolvedIds

Other catalog objects referenced by this index, e.g. the object we’re indexing.

cluster_id: ClusterId

Cluster this index is installed on.

custom_logical_compaction_window: Option<CompactionWindow>

Custom compaction window, e.g. set via ALTER RETAIN HISTORY.

is_retained_metrics_object: bool

Whether the table’s logical compaction window is controlled by the ‘metrics_retention’ session variable.
