public class FlinkAggregateProjectMergeRule
extends org.apache.calcite.rel.rules.AggregateProjectMergeRule

Extends calcite's AggregateProjectMergeRule, modification: consider the timeAttribute field when analyzing interesting fields for the LogicalWindowAggregate node while normal Aggregate node needn't.

FLINK modifications are at lines

1. Should be removed after legacy groupWindowAggregate was removed: Lines 85 ~ 105, Lines 136 ~ 156
