Class RuntimeFilterRecordBatch
java.lang.Object
org.apache.drill.exec.record.AbstractRecordBatch<RuntimeFilterPOP>
org.apache.drill.exec.record.AbstractUnaryRecordBatch<RuntimeFilterPOP>
org.apache.drill.exec.record.AbstractSingleRecordBatch<RuntimeFilterPOP>
org.apache.drill.exec.physical.impl.filter.RuntimeFilterRecordBatch
- All Implemented Interfaces:
AutoCloseable,Iterable<VectorWrapper<?>>,CloseableRecordBatch,RecordBatch,VectorAccessible
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.
