org.apache.calcite.rel.rules.AggregateExtractProjectRule

org.apache.flink.table.plan.rules.logical.ExtendedAggregateExtractProjectRule

public class ExtendedAggregateExtractProjectRule
extends org.apache.calcite.rel.rules.AggregateExtractProjectRule

Rule to extract a Project from a LogicalAggregate, a LogicalWindowAggregate or a TableAggregate and push it down towards the input.

Note: Most of the logic in this rule is same with AggregateExtractProjectRule. The difference is this rule has also taken the LogicalWindowAggregate and TableAggregate into consideration. Furthermore, this rule also creates trivial Projects unless the input node is already a Project.
