public final class DeduplicateAggs
extends ReplaceAggregateAggExpressionWithEval
implements OptimizerRules.CoordinatorOnly

This rule handles duplicate aggregate functions to avoid duplicate compute stats a = min(x), b = min(x), c = count(*), d = count() by g becomes stats a = min(x), c = count(*) by g | eval b = a, d = c | keep a, b, c, d, g
