CoalesceShufflePartitions

case class CoalesceShufflePartitions(session: SparkSession) extends Rule[SparkPlan] with AQEShuffleReadRule with Product with Serializable

A rule to coalesce the shuffle partitions based on the map output statistics, which can avoid many small reduce tasks that hurt performance.
