返回CoprocessorIterator的com.pingcap.tikv.operation.iterator中的方法

限定符和类型	方法和说明
static CoprocessorIterator<Handle>	CoprocessorIterator.getHandleIterator(TiDAGRequest req, List<org.tikv.common.util.RangeSplitter.RegionTask> regionTasks, ClientSession clientSession) Build a DAGIterator from TiDAGRequest and region tasks to get handles When we use getHandleIterator, we must be preforming a IndexScan.
static CoprocessorIterator<Row>	CoprocessorIterator.getRowIterator(TiDAGRequest req, List<org.tikv.common.util.RangeSplitter.RegionTask> regionTasks, ClientSession clientSession) Build a DAGIterator from TiDAGRequest and region tasks to get rows When we are preforming a scan request using coveringIndex, IndexScan should be used to read index rows.
static CoprocessorIterator<TiChunk>	CoprocessorIterator.getTiChunkIterator(TiDAGRequest req, List<org.tikv.common.util.RangeSplitter.RegionTask> regionTasks, ClientSession clientSession, int numOfRows) Build a DAGIterator from TiDAGRequest and region tasks to get rows When we are preforming a scan request using coveringIndex, IndexScan should be used to read index rows.
