Uses of TiDAGRequest in org.tikv.common

Methods in org.tikv.common with parameters of type TiDAGRequest

Modifier and Type	Method and Description
Iterator<Long>	Snapshot.indexHandleRead(TiDAGRequest dagRequest, List<RangeSplitter.RegionTask> tasks) Below is lower level API for env like Spark which already did key range split Perform handle scan
