Type Members

1. case class CoprocessorRDD(output: Seq[Attribute], tiRdds: List[TiRDD]) extends SparkPlan with LeafExecNode with Product with Serializable

2. case class HandleRDDExec(tiHandleRDDs: List[TiHandleRDD]) extends SparkPlan with LeafExecNode with Product with Serializable

   HandleRDDExec is used for scanning handles from TiKV as a LeafExecNode in index plan.

3. 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.
