Class RuntimeFilterRecordBatch

java.lang.Object

org.apache.drill.exec.record.AbstractRecordBatch<T>

All Implemented Interfaces:

AutoCloseable, Iterable<VectorWrapper<?>>, CloseableRecordBatch, RecordBatch, VectorAccessible

public class RuntimeFilterRecordBatch
extends AbstractSingleRecordBatch<RuntimeFilterPOP>

A RuntimeFilterRecordBatch steps over the ScanBatch. If the ScanBatch participates in the HashJoinBatch and can be applied by a RuntimeFilter, it will generate a filtered SV2, otherwise will generate a same recordCount-originalRecordCount SV2 which will not affect the Query's performance ,but just do a memory transfer by the later RemovingRecordBatch op.
