public class BeamAggregateProjectMergeRule
extends org.apache.beam.vendor.calcite.v1_28_0.org.apache.calcite.rel.rules.AggregateProjectMergeRule

This rule is essentially a wrapper around Calcite's AggregateProjectMergeRule. In the case when an underlying IO supports project push-down it is more efficient to not merge Project with an Aggregate, leaving it for the BeamIOPUshDownRule.
