Struct tidb_query_executors::util::aggr_executor::Entities [−][src]
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.
