DecimalAggregates

Related Doc: package optimizer

object DecimalAggregates extends Rule[LogicalPlan]

Speeds up aggregates on fixed-precision decimals by executing them on unscaled Long values.

This uses the same rules for increasing the precision and scale of the output as org.apache.spark.sql.catalyst.analysis.HiveTypeCoercion.DecimalPrecision.
