Class BeamAggregateProjectMergeRule

  • All Implemented Interfaces:
    org.apache.beam.vendor.calcite.v1_40_0.org.apache.calcite.rel.rules.TransformationRule
    public class BeamAggregateProjectMergeRule
extends org.apache.beam.vendor.calcite.v1_40_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.
