pub fn aggregate_expressions(
aggr_expr: &[Arc<AggregateFunctionExpr>],
mode: &AggregateMode,
col_idx_base: usize,
) -> Result<Vec<Vec<Arc<dyn PhysicalExpr>>>, DataFusionError>Expand description
Returns physical expressions for arguments to evaluate against a batch.
The expressions are different depending on mode:
- Partial: AggregateFunctionExpr::expressions
- Final: columns of
AggregateFunctionExpr::state_fields()
