CollectHandles

case class CollectHandles(child: Expression, mutableAggBufferOffset: Int = 0, inputAggBufferOffset: Int = 0) extends ImperativeAggregate with Product with Serializable

An aggregation function that are expressed in terms of imperative initialize(), update(), and merge() functions which operate on Row-based aggregation buffers.

This CollectHandles is used for collecting handles from TiKV to a list and serves as an aggregation function used in org.apache.spark.sql.execution.RegionTaskExec
