getSupportedEncodings
Description copied from interface:Prel
Supported 'encodings' of a Prel indicates what are the acceptable modes of SelectionVector of its child Prel- Specified by:
getSupportedEncodings
in interfacePrel
-
getEncoding
FilterPrel adds an SV2 (TWO_BYTE mode SelectionVector).- Specified by:
getEncoding
in interfacePrel
-
needsFinalColumnReordering
public boolean needsFinalColumnReordering()- Specified by:
needsFinalColumnReordering
in interfacePrel
-
prepareForLateralUnnestPipeline
Description copied from interface:Prel
If the operator is in Lateral/Unnest pipeline, then it generates a new operator which knows how to process the rows accordingly during execution. eg: TopNPrel -> SortPrel and LimitPrel Other operators like FilterPrel, ProjectPrel etc will add an implicit row id to the output.- Specified by:
prepareForLateralUnnestPipeline
in interfacePrel
