Fields

group_by_columns: Vec<String>

Raw stored column names build_group_key reads from each scanned row.

group_by_output_names: Vec<String>

Issue #1763: SELECT OUTPUT name per grouped dimension (parallel to group_by_columns); finalize_group emits the value under this name so it equals the metadata column name (both from select_naming). Alias when projected with one, else the column name.

aggregates: Vec<AggregateComputation>
