RegionTaskExec

case class RegionTaskExec(child: SparkPlan, output: Seq[Attribute], dagRequest: TiDAGRequest, tiConf: TiConfiguration, ts: TiTimestamp, session: TiSession, sparkSession: SparkSession) extends SparkPlan with UnaryExecNode with Product with Serializable

RegionTaskExec is used for issuing requests which are generated based on handles retrieved from HandleRDDExec aggregated by a SortAggregateExec with org.apache.spark.sql.catalyst.expressions.aggregate.CollectHandles as aggregate function.

RegionTaskExec will downgrade a index scan plan to table scan plan if handles retrieved from one region exceed spark.tispark.plan.downgrade.index_threshold in your spark config.

Refer to code in com.pingcap.tispark.TiDBRelation and CoprocessorRDD for further details.
