Some common data that need to be accessed by both AggregationExecutor and AggregationExecutorImpl.

Fields

src: Srccontext: EvalContextschema: Vec<FieldType>
[−]

The schema of the aggregation executor. It consists of aggregate result columns and group by columns.

each_aggr_fn: Vec<Box<dyn AggrFunction>>
[−]

The aggregate function.

each_aggr_cardinality: Vec<usize>
[−]

The (output result) cardinality of each aggregate function.

each_aggr_exprs: Vec<RpnExpression>
[−]

The (input) expression of each aggregate function.

all_result_column_types: Vec<EvalType>
[−]

The eval type of the result columns of all aggregate functions. One aggregate function may have multiple result columns.
