Summary for a persistent-session relation delta update.

Fields

input_delta_count: usize

Number of relation delta entries supplied by the caller before coalescing.

changed_relations: usize

Number of changed relation names in the delta batch.

changed_relation_names: Vec<String>

Changed relation names after coalescing.

insert_rows: u64

Total inserted rows across all changed relations.

delete_rows: u64

Total deleted rows across all changed relations.

has_deletes: bool

True when at least one relation supplied delete rows.

affected_sccs: usize

Number of SCCs whose dependency closure was affected.

recomputed_sccs: usize

Number of affected SCCs that were cleared and fully recomputed.

incremental_sccs: usize

Number of affected SCCs updated without clearing prior output.

coalesced_insert_rows: u64

Net insert rows after batch coalescing and insert/delete cancellation.

coalesced_delete_rows: u64

Net delete rows after batch coalescing and insert/delete cancellation.

canceled_rows: u64

Rows canceled because an insert and delete for the same relation matched in the batch.

planner_telemetry: DeltaPlannerTelemetry

Planner-grade cache, fallback, and speedup telemetry.

debug_trace: Vec<String>

Metadata-only debug trace for the delta recompute.
