SortBasedAggregationIterator

class SortBasedAggregationIterator extends AggregationIterator

An iterator used to evaluate AggregateFunction. It assumes the input rows have been sorted by values of groupingKeyAttributes.

    The distinct modes of AggregateExpressions.

    The distinct modes of AggregateExpressions. Right now, we can handle the following mode:

    • Partial-only: all AggregateExpressions have the mode of Partial;
    • PartialMerge-only: all AggregateExpressions have the mode of PartialMerge);
    • Final-only: all AggregateExpressions have the mode of Final;
    • Final-Complete: some AggregateExpressions have the mode of Final and others have the mode of Complete;
    • Complete-only: nonCompleteAggregateExpressions is empty and we have AggregateExpressions with mode Complete in completeAggregateExpressions; and
    • Grouping-only: there is no AggregateExpression.
