org.apache.flink.compiler.dataproperties.LocalProperties.filterByNodesConstantSet()
Filters these properties by what can be preserved through a user function's constant fields set. @param node The optimizer node that potentially modifies the properties. @param input The input of the node which is relevant. @return True, if the resulting properties are non trivial.

      gProps = dps.computeGlobalProperties(gProps);
      lProps = dps.computeLocalProperties(lProps);
      
      // filter by the user code field copies
      gProps = gProps.filterByNodesConstantSet(this, 0);
      lProps = lProps.filterByNodesConstantSet(this, 0);
      
      // apply
      node.initProperties(gProps, lProps);
      node.updatePropertiesWithUniqueSets(getUniqueFields());
      target.add(node);
